Verified step by step guidance

Understand the anatomy of the ulnar nerve: The ulnar nerve is one of the major nerves of the upper limb, originating from the brachial plexus and traveling down the arm to the hand. It is responsible for motor and sensory innervation to specific muscles and skin areas.

Identify the anatomical regions mentioned in the question: The options provided are 'Deltoid tuberosity,' 'Cubital tunnel,' 'Anatomical snuffbox,' and 'Carpal tunnel.' Each of these regions corresponds to a specific location in the upper limb.

Focus on the elbow region: The question specifies the anatomical region the ulnar nerve passes through at the elbow. This narrows the focus to structures located near the elbow joint.

Analyze the cubital tunnel: The cubital tunnel is a passageway located on the medial side of the elbow, formed by the medial epicondyle of the humerus, the olecranon of the ulna, and a ligament connecting these structures. The ulnar nerve passes through this tunnel as it travels from the upper arm to the forearm.

Eliminate incorrect options: The 'Deltoid tuberosity' is located on the humerus and is unrelated to the elbow. The 'Anatomical snuffbox' is a depression on the lateral side of the wrist, and the 'Carpal tunnel' is a passageway in the wrist for the median nerve, not the ulnar nerve. Therefore, the correct answer is the 'Cubital tunnel.'
