Answer 1

Hi,

As this is a very long and exhaustive list, answering few of them below.

Muscle	Origin	Insertion	action
Pectoralis major (C)	The pectoralis major consists of two heads. One of the heads is called the clavicular head, which originates on the inside part of the clavicle (collarbone). The other head is called the sternal head, and it originates from three different areas, which include: Outside border of the sternum (breast plate), Costal cartilages of the top six ribs (cartilage extensions at the front of each rib), Aponeurosis of the external oblique muscle (fibrous tissue of the external oblique)	Both the clavicular and sternal heads of the pectoralis major muscle have the same two points of insertion. These two points of insertion are both located on the humerus, which is the long bone of the upper arm.	to move the humerus or upper arm
Pectoralis minor (C)	from the front surfaces of the third, fourth, and fifth ribs on each side of the rib cage	From these three locations, the muscle extends up the chest and inserts on the coracoid process of the scapula (shoulder blade).	to move the scapula or shoulder blade
Serratus anterior (C)	The serratus anterior is a muscle that is located on each side of the chest. Specifically, this muscle begins from the rib cage, extends diagonally upward, and attaches to the scapula (shoulder blade.)	The serratus anterior causes several different actions of the scapula and upper extremities of the body.	When you move your arm up to the front of the body, the serratus anterior muscle pulls the scapula forward, giving the arm more mobility and movement in this direction.
Muscle	Origin	Insertion	action
Deltoid (A)	Since the deltoid muscle is divided into three different sections, this muscle has multiple points of origin.	The lateral (outside) portion of the clavicle, which is also known as the collarbone.The acromion process and the spine of the scapula (shoulder blade).Spine of the scapula	the deltoid muscle is responsible for many different actions of the arm around the shoulder joint
Triceps brachii (A)	The triceps brachii is the muscle that runs down the back of the humerus, which is the long bone of the upper arm, and ends at the top of the ulna, which is the long bone of the forearm.	The muscle fibers from all three heads converge together and insert onto the olecranon process, the round prominence at the back and top of the ulna.	The primary function of the triceps brachii is to extend the forearm. Forearm extension involves the straightening of the arm at the elbow joint.
