Question

Scapula is the part of
A. Skull
B. Pelvic Girdle
C. Pectoral Girdle
D. Vertebral column

Answer 1

Hint: Pectoral Girdle helps in the articulation of the bones of forelimbs with the axial skeleton. Clavicle and scapula contained in Pectoral Girdle. The flat bones are called scapula situated in the dorsal part of the thorax situated between the second and the seventh ribs. A long bone with two curvatures is called Clavicle.

Complete answer:
> Option C: Pectoral girdle:
- Clavicles and a scapula are a part of the Pectoral Girdle.
- The triangular flat body of the scapula has a slightly elevated ridge called the spine, diagonally across on the dorsal surface.

> Option A: Skull:
- There are eight flat bones in the cranium, they are articulated immovably with the help of fibrous connective tissue forming sutures.
- The facial region has 14 skeletal elements.

> Option B: Pelvic Girdle:
- Pelvic girdle helps in articulating the bones of the hind limbs with the axial skeleton.
- Each half of the pelvic girdle consists of one coxal bone, which is formed by the fusion of three bones-ilium, ischium and pubis.

> Option D: Vertebral column:
- Vertebrae is formed by a series of 26 bones.
- It extends from the base of the occipital bone of the skull to the entire length of the trunk.
- Vertebral column forms the main framework of the body which articulates with the skull, Pectoral Girdle, pelvic Girdle and serves as the point of attachment of ribs and musculature of the back.

Hence, the correct answer is option (C).

Note: Bones and cartilage constitutes our skeletal system. Scapula is a large triangular flat bone. A long bone with two curvatures called Clavicle. The scapula body has a slightly elevated ridge called the spine like flat, dorsal and triangular body which projects as a flat, expanded process called the acromion. Pectoral girdle helps in the articulation of the bones of forelimbs with the axial skeleton.
