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.
No, the coronoid fossa is on the lateral and anterior aspect of the humerus. It receives the coronoid process of the ulna during flexion of the elbow.
The subscapularis muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus. Its function is to rotate the head of the humerus medially.
Brachialis - attaches from the anterior proximal humerus to the coronoid process of the ulna - strong flexor of the elbowBrachioradialis - attaches from the lateral supracondylar ridge of the humerus to the distal styloid of the radius - weak flexor of the elbow
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.
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.
Elevation of the humerus and slight medial roataion of the shoulder. The anterior deltiod is a semi-weak muscle.
The biceps brachii muscle.
Only pectoralis major seems like that.
