Question

Anatomy Tutorial: Nerves of the Upper Limb

Answer 1

note: my professor is asking us to memorize this diagram so this tutorial will only be covering positions + names, not functions of these nerves



i've flipped the original diagram for teaching purposes

Answer 2

will start off with the five cervial nerves and one thoracic nerve involved in the brachial plexus (C4, C5, C6, C7, C8, T1) + the scapular nerves

Answer 3

for this diagram only, label the brachial plexus with a bracket and divide into the superior middle and inferior trunks

Answer 4

next four labels: musculocutaneous, median, ulnar nerves on the left side, whereas the radial nerve encompasses the whole upper arm on the right side

Answer 5

descending to the forearm, between the elbow and wrist, identify where the interosseus membrane would be

top part gets the anterior antebrachial interosseus nerve and the lower end gets the anterior interosseus nerve. easy to remember --> the antebrachial one is closer to the antebrachium

Answer 6

sandwiched in between them are the ulnar nerve and median nerve. they're in reverse order of the previous instance so be careful.

Answer 7

unfortunately these next two are kind of hard to remember but here we go

lateral antebrachial cutaneous nerve
superficial branch of the radial nerve

Answer 8

fortunately the last three are v. simple
