Verified step by step guidance

Step 1: Understand the anatomy of the biceps brachii muscle. The biceps brachii is a two-headed muscle located in the upper arm. It plays a key role in flexing the elbow and supinating the forearm.

Step 2: Review the concept of muscle insertion points. The insertion point is the site where the muscle attaches to the bone it moves during contraction. For the biceps brachii, this attachment is crucial for its function.

Step 3: Identify the insertion point of the biceps brachii. The biceps brachii inserts at the radial tuberosity, which is a bony prominence on the radius bone in the forearm. This allows the muscle to flex the elbow and supinate the forearm effectively.

Step 4: Compare the other options provided in the question. The greater trochanter is part of the femur and unrelated to the biceps brachii. The olecranon process is part of the ulna and serves as the insertion point for the triceps brachii. The coracoid process is part of the scapula and serves as the origin point for the short head of the biceps brachii, not the insertion.

Step 5: Conclude that the radial tuberosity is the correct insertion point for the biceps brachii muscle, based on its anatomical location and function.
