The triceps brachii muscle is the muscle that attaches on the olecranon process of the ulna. The triceps brachii muscle extends the elbow joint.
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
The Coracoid process of the ulna is a triangular projection with a rough surface. The Coracoid process is the insertion site for the brachialis muscle.
The depression on the ulna into which the humerus inserts is called the trochlear notch. This forms the hinge joint known as the elbow joint.

The triceps muscle is the primary muscle used in a cable extension.
Triceps Brachii - it is the only muscle fleshing out the posterior humerus; its three heads arise from the shoulder girdle and proximal humerus, and it inserts into the olecranon process of the ulna. It is a powerful prime mover of elbow extension.triceps brachii
The triceps and the brachialis both attach to the ulna.
The Coracoid process of the ulna is a triangular projection with a rough surface. The Coracoid process is the insertion site for the brachialis muscle.
