Introduction:

Pectoral girdle also called the shoulder girdle connects our arms and is found in the appendicular skeleton. The upper limb is joined with the axial skeleton by the pectoral girdle. It is form of two bones- clavicle and scapula. Its main function is to provide full motion and support to our shoulders.

Answer to Problem 1PL

Correct answer:

The correct answer is option (a) pectoral gridle.

Explanation of Solution

Explanation/justification for the correct answer:

Option (a) pectoral gridle. Scapula is also known as the wing bone or the shoulder blade. The flat bone is found in the thoracic cavity and is the point of attachment for intrinsic, extrinsic and rotating muscles. The upper arm bone is connected to the collar bone by the scapula.

Clavicle, the collar bone acts as a strut between shoulder blade and the sternum. Scapula connects the upper arm bone with the collar bone. Hence, it is the correct answer.

Explanation for incorrect answer:

Option (b) pelvic gridle- Pelvic gridle is composed of fused bones- the ischium, Ilium and pubis. Hence, it is an incorrect answer.

Option (c) upper limb- There are 30 bones in the upper limb. It is divided into three regions - the arm, forearm and wrist joints. Hence, it is an incorrect answer.

Option (d) axial skeleton- It is a part of the main skeleton and consist of the head and trunk bones of the vertebrate. Hence, it is an incorrect answer.

Conclusion

The correct option is (a) as the pectoral gridle is composed of scapula and clavicle.
