Final answer:
The long head of the biceps tendon passes through the bicipital groove. Additionally, the triceps brachii extends the forearm and the wrist flexors originate from the medial epicondyle of the humerus.
Step-by-step explanation:
The structure that passes through the bicipital groove is c) The long head of the biceps tendon.
