(c) In human six ribs are vertebrochondral

(d) Human ribs are bicephalic

How many of the above statements are incorrect?​

Answer 1

Answer:

The appendicular skeleton includes all of the limb bones, plus the bones that unite each limb with the axial skeleton (Figure 1). The bones that attach each upper limb to the axial skeleton form the pectoral girdle (shoulder girdle). This consists of two bones, the scapula and clavicle (Figure 2). The clavicle (collarbone) is an S-shaped bone located on the anterior side of the shoulder. It is attached on its medial end to the sternum of the thoracic cage, which is part of the axial skeleton. The lateral end of the clavicle articulates (joins) with the scapula just above the shoulder joint. You can easily palpate, or feel with your fingers, the entire length of your clavicle.
