The subscapularis is a muscle located at the front of the shoulder, part of the rotator cuff group. It originates from the subscapular fossa of the scapula and inserts into the lesser tubercle of the humerus. This muscle primarily functions to medially rotate the arm and stabilize the shoulder joint. Its proper function is essential for a range of movements involving the upper limb.
What else can I help you with?
Is the pectoratealis major anterior or posterior to subscapularis muscle?
The pectoralis major muscle is anterior to the subscapularis muscle. The pectoralis major is located on the front of the chest, while the subscapularis is situated on the anterior surface of the scapula, towards the back of the thoracic cavity. Thus, in relation to the subscapularis, the pectoralis major is positioned in front.

Where does subscapularis insert?
the lesser tubercle of the humerus
Is the pectoralis major muscle anterior or posterior to the subscapularis muscles?
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.

What muscles internally rotate shoulder?

What movement occurs when the subscapularis contracts concentrically?
When the subscapularis muscle contracts concentrically, it performs internal rotation of the shoulder joint. This movement involves rotating the arm inward toward the midline of the body.
What is the prime mover for shoulder internal rotation?
The prime mover for shoulder internal rotation is the subscapularis muscle, which is one of the four muscles that make up the rotator cuff. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. Contraction of the subscapularis muscle causes internal rotation of the shoulder joint.
