The arm will return to its original position
Damage to the pectoralis major muscle can result in weakness or loss of movement in the shoulder, such as difficulty with arm adduction (bringing the arm towards the body) and medial rotation (turning the arm inwards). It can also cause pain and dysfunction in the chest and shoulder area.
Do you mean flexion and (abd)uction?? If so, the prime mover would be the deltoid muscle with many smaller muscles assisting. If you are in fact meaning flexion and adduction, the prime mover would be the pectoralis major and the latissimus dorsi with many smaller muscles assisting.
No, the pectoralis major and pectoralis minor are not antagonistic muscles. They are both located in the chest region and work together to perform movements like shoulder adduction and internal rotation. Antagonistic muscles work in opposition to each other.
The pectoralis major muscle is anterior to the subscapularis muscles, as it lies in front of the shoulder joint and rib cage. The subscapularis muscles are located on the posterior aspect of the shoulder blade and assist in internal rotation of the arm.
The pectoralis major muscle is responsible for movements of the shoulder joint, such as flexion, adduction, and medial rotation of the arm. It also helps in stabilizing the shoulder joint during various activities like pushing, pulling, and lifting objects.
Pectoralis moves the shoulder joint. It has a sternal and clavicular end , it helps in shoulder joint adduction, cross arm adduction and overhead. Adduction movement means bringing the shoulder towards midline
Yes, the pectoralis major is responsible for movements like arm flexion and horizontal adduction of the shoulder. In contrast, the pectoralis minor is involved in stabilizing the scapula by drawing it forward and downward.
The pectoralis major and pectoralis minor are two muscles located in the chest of mammals. The pectoralis major is a large, thick muscle responsible for the movement of the shoulder joint, aiding in actions such as flexion, adduction, and internal rotation of the arm. The pectoralis minor is smaller and lies underneath the pectoralis major, primarily functioning to stabilize the scapula and assist in movements such as scapular protraction and depression. Together, these muscles play crucial roles in upper limb movement and shoulder stability.
I do not have a pectoralis muscle, as I am an artificial intelligence virtual assistant. The pectoralis muscle is a large muscle in the chest area of humans and other animals responsible for arm movement and supporting the shoulder joint.

Because shoulder horizontal adduction is performed when the arm is horizontal position (i.e., the elbow is level with shoulder) and adduction is movement toward the center of the body, shoulder horizontal adduction is performed primarily by pectoralis major and anterior deltoid, with an assist by latissimus dorsi.
The pectoralis major is a large chest muscle that is responsible for flexing, adducting, and internally rotating the arm at the shoulder joint. It also helps to stabilize the shoulder joint during movement.
The muscle that flexes and adducts the arm at the shoulder, working alongside the pectoralis major, is the latissimus dorsi.
The inner pectoral muscle, also known as the pectoralis minor, helps to stabilize and move the shoulder blade, allowing for proper movement of the shoulder joint.
