Anterior interosseous artery

boundaries in the cubital fossa

medial: pronator teres

lateral: brachioradialis

superior: line between medial and lateral epicondyles

roof: bicippital aponeruosis

floor: brachialis and supinator

contents of the cubital fossa

median nerve

brachial artery (+ulnar and radial arteries)

biceps brachii tendon

what does the brachial artery split into and where

ulnar and radial arteries at the cubital fossa

median nerve enters the forearm

at the cubital fossa

what muscle splits the median nerve

pronator teres

what does the median nerve split into

anterior interosseuous nerve

palmar branch

which nerve supplies the deep anterior forearm muscles

anterior interosseous (median)

how does the ulnar nerve branch in the forearm

dorsal branch

palmar branch

how does the ulnar nerve enter the forearm

at the medial epicondyle

all muscles in the anterior forearm are supplied by the median nerve besides _

flexor carpi ulnaris

half of Flexor Digitorum Profundus

which forearm muscle is innervated by 2 nerves

flexor digitorum profundus

deep branch

superficial branch

what is unique about the brachioradialis

flexes the wrist despite being in the posterior compartment

numbness in pinky and part of the ring finger

fibrous capsule of the elbow function

provides stability

ulnar collateral ligament and radial collateral ligament functions

stabilizing the elbow during movement

annular ligament of the radius function

prevents the radius from moving during supination/pronation
