Question

When making an incision on the surface of the forearm from the center of the antecubital fossa to the point between the fourth and fifth digits, which of the following arteries would be raised?

a. Radial artery
b. Ulnar artery
c. Brachial artery
d. Axillary artery

Answer 1

The ulnar artery would be raised when making an incision from the antecubital fossa to the area between the fourth and fifth digits of the forearm.

Step-by-step explanation:

When making an incision on the surface of the forearm from the center of the antecubital fossa to the point between the fourth and fifth digits, the artery that would be raised is the ulnar artery. The brachial artery, after exiting the axillary region and supplying much of the brachial region, bifurcates at the coronoid fossa into the radial and ulnar arteries. These two arteries travel down the forearm parallel to their respective bones and extend into the wrist and hand, forming the palmar arches that supply blood to the digits. In following the path of such an incision on the forearm, it is evident that the ulnar artery, which runs alongside the ulna (the medial bone of the forearm) and towards the ulnar side of the hand, would be the vessel encountered.
