MUSCULUS GENIOHYOIDEUS Meaning and
Definition
-
The musculus geniohyoideus, commonly referred to as the geniohyoid muscle, is a small and delicate muscle located in the anterior region of the neck. It encompasses the geniohyoid portion of the anterior throat and plays an important role in certain physiological activities.
Anatomically, the geniohyoid muscle is a bilateral muscle, meaning it is present on both sides of the neck. It originates from the inferior mental spine of the mandible, which is a prominent bony ridge located on the inner surface of the lower jawbone. It then extends downwards and backwards to attach to the body of the hyoid bone. The hyoid bone is a U-shaped bone situated in the anterior part of the neck, just above the thyroid cartilage.
The primary function of the musculus geniohyoideus is to elevate and stabilize the hyoid bone. It accomplishes this by contracting and pulling the hyoid bone superiorly, thereby assisting in an array of important actions such as swallowing, tongue movements, and speech production. Additionally, it contributes to the forward movement of the tongue, providing support and maintaining the correct positioning of the tongue during various activities involving tongue motion.
While smaller compared to other neck muscles, the musculus geniohyoideus is an integral part of the intricate musculature of the neck, working in coordination with other muscles to facilitate the proper functioning of vital processes.
