MUSCULUS CERATOCRICOIDEUS Meaning and
Definition
-
Musculus ceratocricoideus refers to the cricothyroid muscle, which is an intrinsic muscle found in the neck responsible for controlling the position and tension of the vocal cords. It is composed of two parts: the pars recta and the pars oblique. The pars recta, or straight part, arises from the anterior surface of the cricoid cartilage and inserts into the inferior margin of the thyroid cartilage. The pars oblique, or oblique part, originates from the lateral aspect of the cricoid cartilage and inserts into the inferior horn of the thyroid cartilage.
The main function of the musculus ceratocricoideus is to lengthen and tense the vocal cords. This action helps to increase the pitch of the voice during speech and singing. By contracting, the cricothyroid muscle increases the distance between the cricoid and thyroid cartilages, stretching the vocal cords and tightening them. This elongation results in a higher tension, causing the vocal cords to vibrate more rapidly, producing higher-pitched sounds.
The musculus ceratocricoideus is innervated by the external branch of the superior laryngeal nerve, derived from the vagus nerve (cranial nerve X). Damage or dysfunction of this muscle may lead to voice abnormalities and difficulties in vocal cord control. Disorders affecting the cricothyroid muscle can cause hoarseness, voice fatigue, and changes in pitch range.
In summary, the musculus ceratocricoideus, or cricothyroid muscle, is an intrinsic neck muscle involved in adjusting the tension and position of the vocal cords, affecting vocal pitch during phonation.
