Muscle, Geniohyoid (M. Geniohyoideus, Pna, Bna, Jna)

Muscle, geniohyoid

The hyoid-mental muscle (lat. Musculus geniohyoideus) is a paired muscle of the head and neck, located on the lateral surface of the neck. This muscle is involved in the movement of the tongue and hyoid bone, as well as in maintaining the position of the tongue in the mouth.

The muscle layer of the muscle, submandibular-mental, consists of striated muscle tissue and has the shape of a triangle. It starts from the hyoid bone and attaches to the hyoid process of the lower jaw. The muscle fibers of this muscle pass towards the lateral wall of the pharynx.

The function of the geniosubmandibular muscle is to lower the tongue down and forward, as well as maintaining it in this position. In addition, this muscle plays an important role in maintaining the normal position of the tongue in the oral cavity.

With pathology of the muscles, the hyoid-mental muscles, various speech disorders may occur due to difficulty moving the tongue. In some cases, this can lead to difficulty swallowing and breathing.

Thus, the submandibular hyoid muscle is an important muscle in the human body that plays an important role in various functions related to the movement of the tongue and maintaining its position in the oral cavity.
