What else can I help you with?
A muscle that inserts on the greater tubercle of the humerus is most likely involved in what?
lateral rotation
What bone do the muscles of the rotator cuff originate?
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
The muscle you are referring to is the subscapularis muscle. It originates on the subscapular fossa of the scapula and inserts on the lesser tubercle of the humerus. It is responsible for medial rotation of the shoulder joint.
What muscle has an attachment on the superior facet of greater tubercle of humerus?
The supraspinatus muscle has an attachment on the superior facet of the greater tubercle of the humerus. It plays a key role in initiating shoulder abduction and stabilizing the shoulder joint.
What large muscle originates along the sternum and inserts onto the humerus?
You have the pectoralis major muscle in the chest wall. It arise from the sternum and the clavicle. It is inserted on the lateral part of the bicipital groove.
What muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
What does the latissimus dorsi insert to?
on the intertubercular groove of the humerus just lateral to pectoralis major
What muscle originates on scapula and proximal humerus and inserts on olecranon process?
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
What is the large broad sheet of muscle that originates along the thoracic and lumbar vertebra and inserts upon the humerus?
Latissimus dorsi
What muscle originates on the distal anterior humerus and inserts onto the coronoid process of the ulna to cause arm reflexion?
The brachialis muscle originates on the distal anterior humerus and insert at the coronoid process. The function of the brachialis is flexion at the elbow.
What part of the humerus forms the lateral contour of the shoulder?
The greater tuberosity of the humerus forms the lateral contour of the shoulder. The supraspinatus muscle attaches at the greater tuberosity.
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.
