Q

what deep muscle is it?

extensor pollicis longus

Q

what deep muscle is it?

A

abductor pollicis longus

Q

what deep muscle is it?

A

extensor pollicis brevis

Q

what deep muscle is it?

A

supinator muscle

Q

what is the name of the branch of the radial nerve that passes in between the heads of the supinator m?

A

deep branch

when the nerve emerges in the posterior compartment it is the posterior interosseous nerve

Q

what branches does the radial nerve divide into as it enters the lateral aspect of the cubital fossa?

A

superficial branch(runs under brachioradialis)

deep branch
