Is the coronoid fossa on the lateral and posterior side of the humerus?
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.
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
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.
Does the humerus has a coronoid fossa?
yes
The coronoid process articulates with what depression on the distal end of the humerus?
Coronoid fossa
Name the depression on the ulna into which the humerus inserts?
coronoid process
Name a muscle that is a synergistic to the biceps brachii during elbow flexing?
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
What bony landmark of the anterior humerus articulates with the ulna?
TROCHLEA
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 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 primary action of the anterior deltoid?
Elevation of the humerus and slight medial roataion of the shoulder. The anterior deltiod is a semi-weak muscle.
What muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
What muscle originates from the sternum and inserts onto the proximal end of the humerus?
Only pectoralis major seems like that.
