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.

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
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
Name the depression on the ulna into which the humerus inserts?
Trochlear notch
The coronoid process articulates with what depression on the distal end of the humerus?
The depression in the scapula can be either one of four different structures; the supraspinatus fossa, the infraspinatus fossa, the subscapular fossa, or the glenoid fossa. The problem is that none of these articulate with the ulna. The bone you are probably looking for is the humerus, and it articulates with the last one I mentioned, the glenoid fossa.
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 muscle flexes the elbow but neither originates nor inserts on the humerus?
The biceps brachii muscle.
What is the primary action of the deltoids?
Elevation of the humerus and slight medial roataion of the shoulder. The anterior deltiod is a semi-weak muscle.
What is the large broad sheet of muscle that originates along the thoracic and lumbar vertebrae and inserts upon the humerus?
Latissimus dorsi
