🩺 Clinical points & high yield info about the appendix - read below 👇🏼 @rev.med 🧠 Keep learning with us! Tap the link in bio & follow us @rev.med ✅ Overview  The large intestine consist of several parts including the cecum. Attached to the posteromedial end of the cecum is a narrow tube referred to as the Appendix! The appendix has no vital function and it is supported by the mesoappendix, which is a fold that suspends it from the terminal ileum. @rev.med ✅ Clock Face Positions *Pre-ileal: Anterior to the terminal ileum at 1 or 2 o’clock *Post-ileal: Posterior to the terminal ileum at 1 or 2 o’clock *Sub-ileal: Parallel with the terminal ileum at 3 o’clock *Pelvic: Descending over the pelvic brim at 5 o’clock *Subcecal: Below the cecum at 6 o’clock *Paracecal: alongside the lateral border of the cecum at 10 o’clock *Retrocecal: behind the cecum at 11 o’clock (also known as the most common position of the appendix) @rev.med ✅ High Yield Facts Embryonic origin: derived from midgut (so we will see superior mesenteric vessels) *Arterial supply: appendicular artery - from ileocolic artery - from superior mesenteric artery.  *Venous drainage: appendicular vein  *Innervation: Ilecolic branch of the superior mesenteric plexus (travels with the ilecolic artery) *Lymphatic drainage: lymph drains from the appendix into the lymph nodes within the mesoappendix & into ilecolic lymph nodes (which surround the ilecolic artery) @rev.med @rev.med #appendix #REVMED #REVupyourbrain #revmedicine https://www.instagram.com/p/Cfb4PybOtxn/?igshid=NGJjMDIxMWI=

Are you invited to the Knee anastomosis party? Everyones going, see the invite list below... ⤵️ @rev.med    💭 This is one of the best diagrams to use when studying the knee anastomosis. Spend time understanding and seeing the true beauty of its simplicity. Follow along for more 👉🏽 @rev.med   ✅ Overview    The anastomosis around the knee is a network of arterial supply that provides collateral circulation. It’s situated around the patella & around the lower end of the femur & upper end of the tibia. It is an important anastomosis because it compensates for the narrowing of the popliteal artery during prolonged flexion of the knee.    In these diagrams, we look at the right knee with both an anterior and a posterior view. The first artery we have is the base of this anastomosis, known as the Popliteal artery. This artery gives off the 5 genicular branches. @rev.med    ✅ Genicular Branches     The lower limb is supplied by the femoral artery. This artery lies in the femoral triangle and it goes through the adductor canal. It then enters the posterior aspect of the knee after passing through the adductor hiatus of the adductor magnus muscle.     The femoral artery becomes the popliteal artery and goes through a space known as the popliteal fossa, a diamond shaped space on the posterior aspect of the knee. Popliteal artery gives off the lateral superior genicular & medial superior genicular arteries, the lateral inferior genicular & medial inferior genicular arteries. It also gives off the middle genicular branch (supplying the cruciate ligaments of the knee joint). @rev.med    The genicular branches enter into the anterior aspect of the knee joint and form an anastomosis in front of the patella bone.   ✅ More Party People    Femoral artery in the adductor canal gives off the descending genicular branch which divides into superficial and deep branches. The superficial branch goes off with the saphenous nerve and the deep branch descends down and contributes to the anastomosis.     ❗️*Notes continued in the comments*❗️  @rev.med @rev.med https://www.instagram.com/p/Cetdd5lKjhT/?igshid=NGJjMDIxMWI=

Mnemonics to help you learn the Femoral Triangle👇🏼 @rev.med 💭 I promise you nothing is as chaotic as it seems. Nothing is worth diminishing your health. Nothing is worth poisoning yourself into stress, anxiety, and fear. ✅ Overview This lesson walks you through the right anterior thigh showcasing the Femoral Triangle and its content. We’d like for you to always think the ‘Navy Sails’ when labeling the femoral triangle. For the borders recall the mnemonic ‘SAIL’ and for the content inside you’ll use the mnemonic ‘NAVEL’. Let’s see them here: ✅ Mnemonic The borders of the Femoral Triangle are made up the superior border which is the ‘Inguinal Ligament (IL)’, the medial border which is the ‘Adductor longus muscle (A)’, and the lateral border which is the ‘Sartorius muscle (S)’. @rev.med S A I L ⛵️ S: Sartorius muscle - medial border of the sartorius muscle. A: Adductor longus muscle - medial border of this muscle forms the border and the rest of this muscle forms part of the floor of the triangle. IL: Inguinal ligament - which is a ligament that runs from the anterior superior iliac spine to the pubic tubercle. @rev.med The content of the Femoral Triangle contains some of the major neurovascular structures of the lower limb. This mnemonic is used from Lateral to Medial in order. N A V E L ⚓️ N: Femoral nerve - it innervates the anterior compartment of the thigh, and provides sensory branches to the leg and foot. A: Femoral artery - its responsible for the majority of the arterial supply to the lower limb. V: Femoral vein and the great saphenous vein which drains into the femoral vein within the triangle. E: Empty Space - nothing special here L: Lymph vessels and deep inguinal lymph nodes are found here 🧠 Clinical stuff? We’ll discuss in another post. That femoral canal has a lot to teach us. @rev.med @rev.med https://www.instagram.com/p/CewCQtROtQJ/?igshid=NGJjMDIxMWI=

In front of the flexor tendons and middle of the metacarpal bones. It is superficial to long flexor tendons of the digits and deep to palmar aponeurosis.  ⁣⁣@rev.med⁣    *Palmar digital artery: branches off the superficial palmar arch and runs on the ulnar side of the little finger.    *Common palmar digital arteries: there are 3 palmar digital arteries which branch off the superficial palmar arch and run in the webs between fingers. They split into two proper palmar digital arteries that supply adjacent fingers.    *Proper palmar digitals: From the common palmar digitals and run along the sides of the fingers, but not the thumb.⁣⁣⁣⁣    *Superficial palmar branch: Off the radial artery and superficial to the thenar muscles.    👉🏼 Palmar Deep part   *Radial artery: passes into the wrist and hand along the roof of the anatomical snuffbox and then dorsally around the scaphoid and trapezium bone. Passes between 2 heads of 1st dorsal interosseous muscle and then between 2 heads of adductor pollicis to enter into deep palm & form the deep palmar arch. @rev.med    *Princeps pollicis artery: Starts at the radial artery at the palm & descends past 1st metacarpal to proximal phalanx of the thumb.⁣⁣    *Radialis indicis artery: from the radial artery & runs along the lateral side of index finger.⁣⁣⁣⁣    *Deep palmar arch: Continuation of radial artery which anastomoses with the deep branch of ulnar artery.

🤓 We have 4 main curvatures of our Spine! Swipe & read on ⤵️ @rev.med 🧠 Save this post! You might need it later when studying and be sure to follow along @rev.med ✅ Overview The adult vertebral column does not form a straight line, but instead has 4 curvatures along its length. These curves increase the vertebral column’s strength, flexibility, and ability to absorb shock. When the load on the spine is increased, by carrying a heavy backpack for example, the curvatures increase in depth (become more curved) to accommodate the extra weight! They then spring back when the weight is removed. @rev.med The four adult curvatures are classified as either primary or secondary curvatures. Primary curves are retained from the original fetal curvature, while secondary curvatures develop after birth. ✅ Primary curvatures  Thoracic and sacral curvatures are concave anteriorly and are referred to as kyphoses, believe it or not they actually appear during the fetal development time. These two curvatures are considered the primary curvatures. @rev.med ✅ Secondary curvatures  Secondary are the cervical and lumbar curvatures which concave posteriorly and convex anteriorly, referred to as lordoses. They are highlighted to support the head and the upright position of the human posture.  Important about the Lumbar curvature is that it comes into play when an infant begins to present the upright posture when standing or walking. Lumbar curvature is more pronounced in women and ends at the lumbosacral angle (L5 & Sacrum level). @rev.med Sacral curvature differs in men and women in that women sacral curvature is reduced so that the coccyx protrudes less into the pelvic outlet.   🤓 We’ll speak more about the Clinical Conditions soon, such as: Osteoporosis, compression/wedge fracture, chance fracture, axial burst fracture, curvature abnormalities such as Kyphosis (hunchback) - Lordosis - Scoliosis and MORE!

Don't miss out - be sure to follow @rev.med    ✅ Overview    *The radius and ulna are the bones of the forearm. The forearm is the region of the upper limb that extends from the elbow to the wrist.  *The radius bone supports the lateral (thumb) side of the forearm and the ulna bone supports the medial (little finger, pinky) side.   *At the elbow, the radius and ulna articulate with the trochlea and capitulum of the humerus bone. @rev.med    ✅ Movement     *The junction between the humerus and radius is a hinge joint, which permits flexion and extension movements (front to back) of the elbow.  *At the wrist, the radius articulates with the proximal row of carpal bones to form an ellipsoidal joint.  *The junction between the humerus and radius is a hinge joint, which permits flexion and extension movements (front to back) of the elbow.  *At the wrist, the radius articulates with the proximal row of carpal bones to form an ellipsoidal joint.  *This junction permits the wrist to move in two planes, flexion and extension (front to back) and abduction and adduction (side to side).  *The forearm bones also articulate with each other. Proximally, the head of the radius forms a joint with the radial notch of the ulna, and distally, the head of the ulna forms a joint with the ulnar notch of the radius.  *These pivot joints allow the radius to rotate around the ulna, which turns the palm of the hand (pronation and supination). @rev.med    ✅ Also     *An interosseous membrane spans the distance between the medial edge of the radius and the lateral edge of the ulna.  *This thin sheet of connective tissue separates the forearm into anterior and posterior compartments. It also transfers tension from the radius to the ulna and serves as an attachment point for some of the muscles that move the wrist and hand. @rev.med⁣⁣  @rev.med    #Bones #REVmed #REVupyourbrain #revmedicine https://www.instagram.com/p/CSmfSCxrjK2/?utm_medium=tumblr

Swipe & label the diagram. Place your answers below in the comments👇🏿@rev.med    🧠 Share this post and test your friends - studying together is a great method to become better friends 😉     ✅ Overview     The Cerebrum, Cerebellum and brainstem are all drained by veins which empty into the dural venous sinuses.     Within the dura mater - the dural venous sinuses lie between the periosteal & meningeal layers. The scalp, face and CNS are all drained into this system of sinuses. These sinuses are unique however as they do not contain valves! @rev.med    ✅ Venous Sinuses    These valveless veins are 11 in total. The straight, superior, and inferior sagittal sinuses are found in the falx cerebri of the dura mater. They meet at the confluence of sinuses.    The straight sinus is a continuation of the great cerebral vein of Galen and the inferior sagittal sinus. From the confluence, the transverse sinus continues bi-laterally and curves into the sigmoid sinus to meet the opening of the internal jugular vein.⁣⁣ @rev.med  ⁣⁣  The cavernous sinus drains the ophthalmic veins and can be found on either side of the sella turcica. From here, the blood returns to the internal jugular vein via the superior or inferior petrosal sinuses.   ⁣⁣  👀 Critical stuff to know! Sketch out just the sinuses on a paper and label it, repeat till you get it!     Much more coming soon, stay focused, keep at it, and don’t give up no matter what!    @rev.med  @rev.med    #venoussinuses #REVMED #REVupyourbrain #revmedicine https://www.instagram.com/p/CSe4BTLLWos/?utm_medium=tumblr

Remember these important structures to score some points on exam day.  *T1 Apex of the lungs *T2 Sternoclavicular joint *T3 Top of the arch of the aorta *T4/T5 Bifurcation of the trachea; sternal angle *T5 Top of the heart *T6 Center of the roots of the lungs *T8 Inferior vena cava opening in the diaphragm; ventricles of the heart *T9 Inferior angle of the scapula, xiphoid process, inferior extent of the lungs anteriorly at the mid-clavicular line *T10 Esophageal opening in the diaphragm, inferior extent of lungs posteriorly *T12 Aortic opening in the diaphragm, posterior extent of parietal pleura @rev.med *L3 Attachment of the crura of the diaphragm 🧠 Mental Check-in S = Stop Stop what you are doing: Press the pause button on your thoughts and actions. T = Take Take a few deep breaths to center yourself and bring yourself fully into the present moment. O = Observe Observe what is going on with your: Body What physical sensations are you aware of (touch, sight, hearing, taste, smell)? Emotions What are you feeling right now? Mind What assumptions are your making about your feelings? What is the story you’re telling yourself about why you are having them? P = Proceed Proceed with whatever you were doing, making a conscious, intentional choice to incorporate what you just learned. Hope this helps you center your self and begin the studying process! @rev.med @rev.med #heart #REVMED #REVupyourbrain #revmedicine https://www.instagram.com/p/CSZm7rULB6N/?utm_medium=tumblr

Extremely HIGH YIELD Neuro notes👇🏼Read on and share 🧠 @rev.med    Make sure to save this post so you have it when you study! Be sure to follow us for more Neuro Anatomy @rev.med   👀 Please be sure to read these notes - we have literally made it so effectively simple!   ✅ 3 Major white matter column systems     Think of the tracts found in these columns as highways & dirt roads. The Dorsal Column system is a highway, and the Anterior & Lateral Column systems are like dirt roads. Its because the dorsal column is heavily myelinated and fast, and antero-lateral column is poorly myelinated. So the advanced system (the dorsal column) is faster because cars go faster on a highway.  ⁣⁣⁣⁣  Dorsal Column (Dorsal Funiculus) ⁣⁣⁣⁣  *Only ascending tracts. ⁣⁣⁣⁣  *Advanced & Modern sensations⁣⁣⁣⁣  *Highway - high velocity⁣⁣⁣⁣  *Fine touch⁣⁣⁣⁣  *2-point discrimination⁣⁣⁣⁣  *Fast⁣⁣⁣⁣ & More accuracy⁣⁣⁣⁣  *Proprioception - sense of position⁣⁣⁣⁣  *Better localized sensations from specific areas - highway lanes are consistent @rev.med    Anterior & Lateral Column systems  *Both ascending and descending tracts⁣⁣⁣⁣  *Primitive & Old School sensations  *Dirt Roads - low velocity  *Crude touch  *Pain⁣⁣⁣⁣ & Temperature  *Less accuracy ⁣⁣⁣⁣& Slower  *Sexual sensation  * Poorly localized sensations - dirt road lanes vary    ✅ Table to know    Ascending Tracts    *Dorsal Column - Vibration, proprioception, two-point discrimination  *Spinocerebellar (Anterior & Posterior) - Proprioception in joints and muscles  *Spinothalamic:   —Lateral spinothalamic tract - Pain and temperature  —Anterior (ventral) spinothalamic tract - Pressure and crude touch @rev.med    Descending Tracts    *Corticospinal (Anterior & Lateral) - Voluntary, discrete, skilled motor activities   *Reticulospinal (Medial & Lateral) - Regulation to voluntary movements and reflexes  *Tectospinal - Postural movements from visual stimuli   *Vestibulospinal - Inhibition of flexor and promotion of extensor muscle activity   *Rubrospinal - Promotion of flexor and inhibition of extensor muscle activity    @rev.med  @rev.med    #spinalcord #REVMED #REVupyourbrain #revmedicine https://www.instagram.com/p/CSR4aR_LKR0/?utm_medium=tumblr
