What's up Doc?

A mashup of medschool, cases and all sorts of rare and beautiful medical things

Fortunately, after a brief skirmish, I seem to have gained the upper hand in the battle against my internal organs, at least until they learn to read and find out the mean stuff I’ve said about them.

– chewing

– muscles involved      – masseter      – temporalis      – medial pterygoids      – lateral pterygoids

– muscles that close the mouth      – temporalis      – masseter      – medial pterygoids

– muscles that open the mouth       – lateral pterygoids

– muscles involved in retraction       – temporalis

I See Fireworks

The foveola lies within the macula of the primate eye, a region near the center of the retina. It is a small, central pit composed of closely packed cone cells — the cells responsible for color vision — and supporting Muller cells that help maintain the cone cells’ structure and functional stability. Nowhere else are cone receptors longer, slimmer and more densely grouped, giving this region the potential for highest visual acuity in the eye.

Stages of peptic ulcer:

I - erosion - the lesion affects only the mucosa

II - acute ulcer - the lesion affects mucosa and submucosa

III - chronic ulcer - the lesion affects mucosa, submucosa, the muscular layer and the subserosal layer  IV - penetrating/perforating ulcer - the entire stomach wall is affected and there is a communication with other abdominal organs or the peritoneal cavity

Human granulocytes as seen under a microscope. They look very similar, and yet, each has its own unique build and function.

CENTOR score is a simple and easy way to assess the likelihood of a bacterial throat infection. Some places use the age modifier, some don’t. But the important thing is, once you know what you are looking for, it makes the job easier. 

Absence of cough

Tonsillar exudates

History of fever

Tender anterior cervical adenopathy

For a score of 4 or 5, it’s best to give antibiotics empirically, until the throat cultures come back.

64 Codons

Codons, Codon usage bias, Code dictionary, Genetic code, 64 Codons, Wobble hypothesis

A codon is a small section of the genetic material that codes for an amino acid. There are total 64 codons that either code for an amino acid or a stop codon. The image depicting different codons is referred to as codon dictionary. Just like we speak in different languages, our cells use these codons.

Brain Anatomy

Cerebellum - located at the back of the brain beneath the occipital lobes 

Functions: 

Fine tunes motor activity or movement

Assists in maintaining posture, sense of balance or equilibrium, by controlling the tone of muscles and the position of limbs 

Important in one’s ability to perform rapid and repetitive actions

Frontal Lobe -  largest of the four lobes 

Functions:

Motor skills such as voluntary movement, speech, intellectual and behavioral functions

Plays an important part in memory, intelligence, concentration, temper and personality

Occipital Lobe - located at the back of the brain 

Functions:

Enable humans to receive and process visual information

Influence how humans process colors and shapes

Temporal Lobe - located on each side of the brain at about ear level

Functions:

Involved in visual memory and helps humans recognize objects and peoples’ faces

Verbal memory and helps humans remember and understand language

Allows humans to interpret other people’s emotions and reactions.

Parietal Lobe - 

Functions: positioned above the temporal lobe and behind the frontal lobe

interpret simultaneously, signals received from other areas of the brain such as vision, hearing, motor, sensory and memory

Ever had issues picturing the ventricular system of the brain? 

These are some nice illustrations that I find very helpful because it gives me an idea of how it all looks 3D
