4. Enlist two bones of the shoulder girdle. 5. Enlist three bones which fuses to form the coxal bone. 6. Enlist two bones of forearm.

Answer

The answers to the questions based on human skeletal anatomy are as follows: 4. The two bones that make up the shoulder girdle (also known as the pectoral girdle) on each side are the clavicle (collarbone) and the scapula (shoulder blade). 5. The coxal bone (hip bone or pelvic bone) is formed by the fusion of three distinct bones during development: the ilium (the large, superior wing-like portion), the ischium (the posterior-inferior part on which we sit), and the pubis (the anterior-inferior portion). 6. The forearm contains two long bones: the radius (located on the lateral side, same side as the thumb) and the ulna (located on the medial side, same side as the little finger).
