Ans;A. Coracoid process at the top of the scapula.
The muscle represented by an arrow in the picture above is biceps brachii.
- The biceps is a muscle in the upper arm with two heads, called the short head and the long head, which converge into a single mass.
- It is one of the three muscles in the anterior compartment of the arm.
- Both heads of the biceps arise from the scapula in the shoulder, and the muscle attaches to the radius (bone), in the forearm.
- Specifically, the short head of the biceps originates from the coracoid process at the top of the scapula.
- The long head originates from the supraglenoid tubercle just above the shoulder joint.
