Lecture 16 Flashcards
short notes on the proximal aspect forearm
most major blood vessels and nerves pass between arm and forearm through cubital fossa
Short notes on the distally aspect forearm
structures pass between forearm and hand through carpal tunnel
Short notes on the anterior compartment
Muscles that flex wrist and digits and pronate the hand
innervated mostly by median nerve also ulnar nerve
short notes on the posterior compartment
muscles that extend the wrist and digits and supinate the hand
innervated by radial nerve
