The cubital fossa is a triangular depression located on the anterior aspect of the elbow joint.

Here is the answer to question 7:

The cubital fossa is a triangular depression located on the anterior aspect of the elbow joint.

Its components (boundaries and contents) are:

• Superior boundary: An imaginary line connecting the medial and lateral epicondyles of the humerus.
• Medial boundary: The pronator teres muscle.
• Lateral boundary: The brachioradialis muscle.
• Floor: The brachialis and supinator muscles.
• Roof: Skin, superficial fascia (containing the median cubital vein, medial and lateral cutaneous nerves of the forearm), and deep fascia (bicipital aponeurosis).

The main contents of the cubital fossa, from medial to lateral, are:

• Median nerve
• Brachial artery (which typically bifurcates into the radial and ulnar arteries within the fossa)
• Biceps brachii tendon
• Radial nerve (which typically bifurcates into superficial and deep branches within the fossa)
