Verified step by step guidance

Step 1: Understand the anatomy of the flexor carpi radialis muscle. It is one of the muscles in the anterior compartment of the forearm, responsible for flexion and abduction of the wrist.

Step 2: Recall the concept of muscle insertion. The insertion point is where the muscle attaches to the bone that moves during contraction. For the flexor carpi radialis, this is relevant to wrist movement.

Step 3: Analyze the options provided. The bases of the second and third metacarpal bones are located in the hand and are associated with wrist movement, which aligns with the function of the flexor carpi radialis.

Step 4: Eliminate incorrect options. The medial epicondyle of the humerus is the origin of the flexor carpi radialis, not its insertion. The olecranon process of the ulna and the pisiform and hook of hamate are unrelated to the insertion of this muscle.

Step 5: Conclude that the correct insertion point of the flexor carpi radialis muscle is the bases of the second and third metacarpal bones, as this matches its functional role in wrist movement.
