Question 8: Most people have 24 ribs. (True/False) | Question 9: All are the part of sternum except: Clavicle, Manubrium, Xiphoid process, Body.

Answer

For Question 8, the answer is True. The vast majority of humans have 12 pairs of ribs, totaling 24. While anatomical variations like a cervical rib (an extra rib above the first rib) or the absence of the 12th rib can occur, 24 remains the standard count for the human rib cage. For Question 9, the answer is Clavicle. The sternum (breastbone) is composed of three distinct anatomical parts: the manubrium (the upper portion), the body (the middle and largest portion), and the xiphoid process (the small, cartilaginous lower tip). The clavicle, or collarbone, is a separate bone that articulates with the manubrium at the sternoclavicular joint but is considered part of the pectoral girdle, not a structural part of the sternum itself.
