Question

The shoulder blade is made of:
A Clavicle
B Humerus
C Ilium
D Scapula

Answer 1

Hint: The shoulder region is formed by Clavicle, Humerus, and Scapula. The humerus and clavicle are on the ventral side of the body whereas the scapula is on the dorsal side of the body.

Complete step by step answer:
Scapula is placed on the posterior aspect (back side) of the thoracic cage. The scapula is placed on the posterior side of the body. The shoulder blade is made up of scapula. The scapula extends from the second to the seventh ribs.
Clavicle: The clavicle is a long bone. It supports the shoulder so that the arm can swing clearly away from the trunk.
Ilium is a bone of the pelvic girdle. It is fused together with ischium and pubis to form pubic bone.
Humerus: The humerus is the bone of the arm. It is the longest bone of the upper limb. It has an upper end, a lower end, and a shaft.

Hence the correct answer is option(A)

Note: There are a total of 206 bones in the human body.
Axial skeleton (Skull and torso) Mainly the bones which are at the center of the body: 80 bones
Appendicular skeleton (upper limb and lower limb): 126 bones
