How Do You Spell MUSCULUS THYREOHYOIDEUS?

1. The musculus thyreohyoideus, commonly known as the thyrohyoid muscle, is a small intrinsic muscle positioned in the neck region. It is located near the anterior surface of the larynx, specifically connecting the thyroid cartilage (which forms the front part of the voice box) and the hyoid bone (a U-shaped bone located just above the thyroid cartilage).

   The thyrohyoid muscle consists of a thin and flat band-like structure that extends from the thyroid cartilage above to the hyoid bone below. It is primarily responsible for the movement and stabilization of the larynx. When contracted, it elevates and tilts the larynx, assisting in the swallowing process.

   Additionally, the thyrohyoid muscle plays a role in voice production. It cooperates with other muscles involved in vocalization to control the pitch and tension of the vocal cords. By adjusting the position of the larynx, it helps regulate vocal tone and pitch during speech or singing.

   The innervation of the thyrohyoid muscle is supplied by the ansa cervicalis, a part of the cervical plexus. This nerve network originates from the ventral rami (branches) of spinal nerves C1-C3.

   Overall, the musculus thyreohyoideus serves essential functions in both swallowing and vocalization, contributing to the proper functioning of the larynx and assisting in clear speech production.

2. Apparently a continuation of the sternothyreoideus; origin, oblique line of thyroid cartilage; insertion, body of hyoid bone; action, approximates hyoid bone to the larynx; nerve supply, upper cervical through ansa hypoglossi.
