2023年11月3日 · Pronator teres muscle arises by two heads named after their origin sites. The humeral head (superficial head) originates from the medial supracondylar ridge of humerus, located superior to the medial epicondyle of humerus …

2024年5月28日 · The muscle belly of the pronator teres lies deep the brachioradialis muscle in the anterior compartment’s superficial layer, while its proximal part is underneath the flexor digitorum superficialis. The muscle is located laterally from and directly beside the …

The pronator teres is a muscle (located mainly in the forearm) that, along with the pronator quadratus, serves to pronate the forearm (turning it so that the palm faces posteriorly when from the anatomical position).

The pronator teres muscle is a long, round muscle that is located on the anterior aspect of the forearm. This muscle has two different points of origin: the humeral head and the ulnar head. [1] The humeral head is larger and more superficial.

2023年5月1日 · Acting synergistically with the pronator quadratus, the pronator teres pulls the radius medially, which causes the radial head to rotate around the proximal ulna. This pronation movement brings the hand from an upward palm position (supination) to …

2025年1月21日 · Location. The pronator teres is located in the forearm. It spans from the inner (medial) aspect of the elbow, crossing over to the middle portion of the forearm, where it inserts into the radius bone. This positioning allows it to effectively rotate the forearm and hand from a palm-up to a palm-down position.

It is located: - anterior (superficial) to the flexor digitorum superficialis muscle and ulnar artery; - posterior (deep) to the brachioradialis muscle (at its distal end); - lateral to the flexor carpi radialis muscle.

2021年2月28日 · Pronator teres, as the name suggests primarily functions to pronate the forearm, turning the hand posteriorly. It is assisted by its distal counterpart within the deep compartment of the anterior forearm muscles – the pronator quadratus.

It is located laterally in the most superficial layer of the anterior muscles of the forearm. The distal anterior surface of the pronator teres is covered by the brachioradialis muscle [1] [2]. The pronator teres muscle gets its name due to is shape and action.

The Pronator teres has two heads of origin—humeral and ulnar. The humeral head, the larger and more superficial, arises immediately above the medial epicondyle, and from the tendon common to the origin of the other muscles; also from the intermuscular septum between it and the Flexor carpi radialis and from the antibrachial fascia.
