Cubital Fossa

• laterally, brachioradialis muscle
• medially, pronator teres muscle
• superiorly, an imaginary line from the medial and lateral epicondyles.

This circumscribed region contains the median cubital vein, brachial artery and median nerve. Their relationships with each other is important clinically since the median cubital vein is most often used for intravenous injections. Missed injections could be dangerous to the underlying structures.

We will take a look at this region from superficial to deep.
