Verified step by step guidance

Step 1: Understand the anatomy of the brachialis muscle. The brachialis is a muscle located in the upper arm, deep to the biceps brachii. Its primary function is to flex the elbow joint.

Step 2: Review the concept of muscle insertion. The insertion of a muscle is the point where the muscle attaches to the bone that moves during contraction. For the brachialis, this attachment is on the forearm.

Step 3: Analyze the options provided. The coronoid process of the ulna, olecranon process of the ulna, greater tubercle of the humerus, and radial tuberosity are all anatomical landmarks. Determine which one is associated with the brachialis muscle's insertion.

Step 4: Recall that the brachialis muscle inserts specifically on the coronoid process of the ulna. This allows it to flex the elbow by pulling on the ulna during contraction.

Step 5: Eliminate the incorrect options. The olecranon process of the ulna is associated with the triceps brachii, the greater tubercle of the humerus is a site for rotator cuff muscle attachment, and the radial tuberosity is the insertion point for the biceps brachii.
