Last revision before my limbs exam in progress. Colouring and the flashcards are really helpful ☺️🤓
Song of the day
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
