Question

From medial to lateral what is the correct structure order of antecubital fossa: brachial artery, Median and radial nerves?

Answer 1

The correct order of structures in the antecubital fossa from medial to lateral is the median nerve, brachial artery, and radial nerve.

Step-by-step explanation:

The correct structure order of the antecubital fossa, from medial to lateral, is median nerve, brachial artery, and radial nerve.

The median nerve is the most medial structure in the antecubital fossa. It runs alongside the brachial artery and gives off branches that innervate the muscles in the forearm and hand.

The brachial artery is located more centrally compared to the radial nerve. It supplies oxygenated blood to the forearm muscles.

The radial nerve is the most lateral structure in the antecubital fossa. It runs alongside the brachial artery and innervates the posterior muscles of the forearm.
