Tetrapod appendage. In their general plan, pectoral and pelvic appendages are alike; the diagram applies to either. The corresponding names of pectoral and pelvic parts are placed opposite one another, pectoral at the left and pelvic at the right of the part or region. The number of phalanges in each digit is highly variable. In many cases, two small bones or cartilages appear in the position of the centrale. External to the girdle, the tetrapod appendage (Fig. 124) consists of a longitudinal series of three major segments; in the pectoral limb a brachium (upper arm of man), an antebrachium (forearm of man), and a manus (hand); in the pelvic limb a femur (thigh), a cms (shank), and a pes (foot). The proximal segment of each limb contains one long bone, the humerus (pectoral) or femur (pelvic); the middle segment contains two parallel long bones, the radius and ulna (pectoral), or the tibia and fibula (pelvic). In the manus there are three regions—a carpus (wrist) consisting of a group of 9 or possibly 10 compactly arranged small bones, a metacarpal region.
