Term
proximal humerus
Definition

head connects to glenoid

 

surgical neck is proximal border of shaft, site of fractures

 

Greater and lesser tubercle separated by intertubecular groove

Term
radial groove of humerus
Definition
depression in humerus for radial nerve and deep brachial artery
Term
trochlea
Definition
articulates with trochlear notch of the ulna
Term
capitulum of the humerus
Definition
articulates with radius
Term
compartments of the arm
Definition

there are two:

anterior contains the flexor muscles and the musculocutaneus and ulnar nerves

 

posterior contains the extensor muscles and radial nerve

Term
biceps brachii
Definition

flexes and supinates elbow/forearm

short head connects to coracoid

long head connects to supraglenoid

 

bicipital aponeurosis connects to radial tuberosity

 

musculotaneus nerve

brachial artery

Term
Brachialis muscle
Definition

workhorse of elbow flexors

 

deep to biceps

 

attached to humerus and ulna

 

musculoteneous nerve

 

brachial and radial recurrent arteries

Term
coracobrachialis
Definition

flexes and adducts arm, holds up humerus

 

musculocutaneous nerve

 

brachial artery

Term
triceps brachii
Definition

extensor of elbow

 

Three heads:

long connects to infraglenoid tubercle

lateral- connects superior to radial groove

medial- connects inferior to radial groove

all attach at the other end to the posterior ulna and olecranon

 

radial nerve

 

 

Term
anconeus
Definition
locks elbow when extended
Term
brachial artery
Definition

branches below elbow into ulnar & radial terminal branches

 

branches:

profunda brachii (aka deep artery of the arm): largest, giving rise to middle and radial collaterals

superior and inferior ulnar collaterals
