Axillary artery
QuestionChoice
The median nerve is located medial to the brachial artery at this level and it passes between the two heads of the pronator teres muscle to leave the cubital fossa.

b
Median nerve
QuestionChoice
The profunda brachii artery is the first and largest branch of the brachial. It runs on the posterior surface of the humerus with the radial nerve and passes between the medial and long heads of the triceps brachii muscle. It then travels in the spiral groove of the humerus. The image is showing the cubital fossa, which is located at the anterior aspect of the elbow joint, between the arm and forearm. This fossa does not contain the profunda brachii artery.

d
Profunda brachii artery
QuestionChoice
The image shows the cubital fossa of the right arm and the brachial artery is located lateral to the median nerve at this level. It bifurcates into the radial and ulnar arteries at the apex of the cubital fossa. The structures lateral to medial in the cubital fossa can be remembered with the mnemonic "TAN" - **t**endon (biceps tendon), **a**rtery (brachial artery) and **n**erve (median nerve).

*[N.B. the median nerve originally travels lateral to the brachial artery, before crossing anteriorly, to lie medial to the brachial artery]*

Brachial artery
QuestionChoice
The brachial artery divides into the radial and ulnar arteries at the inferior aspect of the cubital fossa, at the level of the radial head. The radial artery then travels along the radial aspect of the anterior compartment of the forearm. It lies beneath the brachioradialis.
