THYROARYTENOID Meaning and
Definition
-
The thyroarytenoid is a term used in medical anatomy to refer to a pair of muscles located within the larynx or voice box. It is also commonly known as the vocalis muscles. Comprised of two separate but closely related muscle components, these muscles extend vertically within the larynx on each side, and are responsible for modulating vocal pitch, tensing the vocal cords, and controlling voice production.
The thyroarytenoid muscles are important for vocalization as they regulate the length and tension of the vocal folds, which directly impacts the quality and pitch of the voice. These muscles are primarily under voluntary control and are activated during speech, singing, and other phonation activities.
The thyroarytenoid muscles are innervated by the recurrent laryngeal branch of the vagus nerve, specifically the external branch of the superior laryngeal nerve. This nerve supply allows for the voluntary control necessary for precise vocal adjustments.
In terms of function, the thyroarytenoid muscles work in tandem with other laryngeal muscles to coordinate phonation and vocalization. Their contraction causes the vocal cords to shorten and thicken, resulting in lower vocal pitch, while their relaxation allows for higher vocal pitch and vibratory flexibility.

2. "Aryteno-": This prefix is derived from the Greek word "arytenes", meaning "ladle-shaped". It refers to the arytenoid cartilages, which are small, ladle-shaped structures located in the larynx.
