Question

what is pectoral ? how is it connected with upper limb?​

Answer 1

Answer: A pectoral girdle, also referred to as the shoulder girdle, connects your upper limbs to the bones along the axis of your body. You have two pectoral girdles in your body. The pectoral girdle consists of the two bones that make up your shoulder: clavicle, or collarbone.

The upper extremity or arm is a functional unit of the upper body. It consists of three sections, the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles.
