Infraspinatus Muscle: The infraspinatus muscle is a thick triangular muscle, which occupies the most part of the infraspinatus fossa. It is one of the four muscles of the rotator cuff, the main function of the infraspinatus is to externally rotate...

The teres major is a muscle of the upper limb. The teres major attaches to the scapula and the humerus. It is a thick but marginally flattened muscle. The teres major is situated superior to the latissimus dorsi and avails...

Coracobrachialis: The coracobrachialis muscle is the smallest of the three muscles that attach to the coracoid process of the scapula. The coracobrachialis is situated at the upper and medial part of the arm. The coracobrachialis lies deep to the biceps...

Brachialis: The brachialis is a muscle in the upper arm that flexes elbow joint. It lies deeper in the biceps brachii and a synergist action that assists the biceps brachii in flexing at the elbow. The brachialis muscle forms the...

Biceps Brachii: Biceps Brachii is a two-headed muscle. The majority of the muscle mass is located anteriorly to the humerus, it has no annexation(attachment) to the bone itself. The tendon of biceps brachii enters the forearm, a connective tissue sheet...

The triceps brachii muscle "three-headed muscle of the arm" is the large muscle on the Posterior Compartment of the upper limb. Triceps Brachii muscle is principally responsible for extension of the elbow joint. Attachments of the triceps brachii muscle Origin:...

The upper arm is between the shoulder and elbow joint. It contains four muscles in two compartments- Anterior compartment Posterior compartment Anterior compartment of the arm Biceps brachii Brachialis Coracobrachialis Nerve Supply: All muscle of the Anterior compartment innervated by...

Heart Anatomy: The heart is a muscular organ that pumps blood into the blood vessels of the circulatory system. Blood provides the body with oxygen and nutrients, as well as aids in the removal of metabolic wastes. The heart is...
