HUMERUS 

Upper end

Head articulates with glenoid cavity

2 necks: anatomical & surgical neck

Anatomical 

separates head from greater & lesser tubercles 

Surgical 

 separates upper end & shaft 

has the axillary nerve & circumflex humeral vessels 

2 tuberosities (Mnemonic for insertions: SIT-S)

Greater tuberosity - insertion of

Supraspinatus muscle 

Infraspinatus muscle 

Teres minor muscle

Lesser tuberosity - insertion of:

Subscapularis muscle 

Bicipital groove 

Contains tendon of long head of biceps 

has 3 lips: (Mnemonic: lady between 2 majors)

Medial lip: Teres major insertion 

Floor: Latissmus dorsi insertion 

Lateral lip: Pectoralis major insertion 

Spiral groove 

Lies posteriorly on the shaft 

Related to radial nerve (winds around it between medial & lateral head of triceps) 

Lower end 

Trochlea -- articulates with ulna 

Capitulum -- articulates with radius 

Medial epicondyle more prominent than lateral epicondyle 

3 fossa: olecranon (posteriorly), radial & coronoid (anteriorly) 

FRACTURES OF HUMERUS - NERVES AFFECTED:

Surgical neck -- injury to axillary nerve --effect: flattened shoulder (deltoid muscle) 

Middle of shaft (spiral groove) -- injury to radial nerve -- effect: wrist drop 

Posterior to medial epicondyle -- injury to ulnar nerve -- effect: claw hand 

Supracondylar fracture -- injury to median nerve

So when non-medical people say "I know this like the back of my hand" do they mean that they don't know anything at all about that topic? Cuz honey trust me you don't know what's in the back of your hand
