Infraspinatus Muscle

The infraspinatus is a thick triangular muscle, which occupies most of the infraspinous fossa. It is among the four Rotator Cuff muscles acting as the mechanical link between the posterosuperior and anterior parts of the rotator cuff. Origin of Infraspinatus Muscle Infraspinatus muscle originates from the medial two-thirds of

Pronator Teres

The pronator teres muscle is found on the palmar side of the forearm, below the elbow. It is assisted by the pronator quadratus to perform its major role i.e, to rotate the forearm palm-down. This position is also referred to as pronation. Origin of Pronator Teres Muscle The pronator teres muscle originates

Teres minor

Teres minor is among the four muscles that contribute to the making of the Rotator Cuff. Its shape is long and narrow and sometimes it may blend into infraspinatus. The primary function of teres minor is to keep the humerus steady in the glenoid fossa in the

Flexor Pollicis Longus

The flexor pollicis longus muscle starts from the surrounding half of the anterior side of the interosseous membrane along with the anterior side of the radius. Through upper two-third of the anterior side of the radius under the anterior oblique line and attaching part of the interosseous

Abductor Pollicis Longus

The abductor pollicis longus muscle emerges via the associated interosseous membrane and the proximal posterior sides of the radius as well as the ulna. Abductor pollicis longus arises in between the extensor digitorum along with extensor carpi radialis brevis muscles within the distal forearm, in order to create
