胸骨舌骨筋 - Musculus sternohyoideus

説明

Origin: Manubrium of sternum

Insertion: Hyoid bone

Nerve: External laryngeal branch of the vagus

Action: Tension and elongation of the vocal folds (has minor adductory effect)

Description:
The Sternohyoideus (Sternohyoid muscle) is a thin, narrow muscle, which arises from the posterior surface of the medial end of the clavicle, the posterior sternoclavicular ligament, and the upper and posterior part of the manubrium sterni. Passing upward and medialward, it is inserted, by short, tendinous fibers, into the lower border of the body of the hyoid bone. Below, this muscle is separated from its fellow by a considerable interval; but the two muscles come into contact with one another in the middle of their course, and from this upward, lie side by side. It sometimes presents, immediately above its origin, a transverse tendinous inscription.
