Answer 34

The radial half of the forearm.

Question 35

Path of the ulnar artery

Answer 35

It branches off of the brachial artery, then travels down the anterior ulnar shaft. It enters the hand at the hypothenar eminence.

Muscles supplied by the ulnar artery

Answer 36

The ulnar half of the forearm.

Question 37
