Step-by-step solution
The pectoral and pelvic girdle bones help in the articulation of the upper and the lower limbs respectively with the axial skeleton.Each half of the pectoral girdle consists of a clavicle and a scapula. The acromion is a slightly elevated ridge in the scapula that projects as a flat, expanded process and articulates with the clavicle. The acetabulum is a cavity at the point of fusion of the ilium, ischium and pubis in the coxal bone and articulates with the thigh bone .The human body consists of 206 bones in total.
