Pectoral Girdle\tThe pectoral girdle is formed of two identical halves.\tEach half of the girdle consists of the following bones — scapula and clavicle.\tScapula:\tThe scapula is also called the shoulder bone.\tIt is the flat, triangular bone located at the back of the thorax.\tIt has a slightly elevated ridge called the spine.\tThe spine projects as a flat, expanded process called the acromion.\tBelow the acromion is a cup-shaped cavity called the glenoid cavity.\tThe glenoid cavity articulates with the humerus of the forelimbs.\tClavicle:It is also called collar bone.It is a rod-shaped bone extending between the neck and the shoulder.\t\tPelvic Girdle\tIt is made of two coxal bones.\tEach coxal bone comprises three bones—ilium, ischium and pubis.\tAt the point where all the three bones fuse is a depression called the acetabulum. The head of the femur articulates with the acetabulum.A line of fusion called the pubic symphysis is observed where the two halves meet
