Question

Coracoid is component of
(A) Fore limb
(B) Skull
(C) Pectoral girdle
(D) Pelvic girdle

Answer 1

Hint: The coracoid process takes place in the scapula. It acts along with the acromion process, helps in stabilizing the joint in the shoulder regions. The coracoid is the hook like structure that joins with the acromion for the movement of arms and the shoulders.

Complete answer:
Three processes take place in the pectoral girdle. It includes the acromion process and the coracoid process. These processes take place in the shoulder. The coracoid connects the parts of the sternum with the shoulder joint. It functions with the humerus and the clavicle. It is a thick curved part which is connected to the neck part of the body.
The pectoral girdle is also known as shoulder girdle which connects the bone along the body axis to the upper limbs of the body. There are two pectoral girdles in the body. The bones that are present in the pectoral girdle are clavicle and the scapula. The scapula is located at the back of the shoulder and it is triangular in cross section. This coracoid present in the scapula joins many muscles in this region. This scapula is divided into medial border, lateral border and the superior border.

Hence the correct answer is option(C)
Note: The pectoral girdles are used to maintain the structural support to the shoulder and the neck bones. They are also helpful in the movement of the arm and the shoulder muscle by the coracoid and acromion process. These girdles are not joined and function independently.
