Its fibers pass backward and lateralward, to be inserted into the base and anterior surface of the arytenoid cartilage.


The lower and deeper fibers of the muscle can be differentiated as a triangular band which is inserted into the vocal process of the arytenoid cartilage, and into the adjacent portion of its anterior surface; it is termed the Vocalis, and lies parallel with the vocal ligament, to which it is adherent.

Larynx (1661 words)
The cricothyroid muscle lies anterior and external to the larynx and was identified in the study of the muscular triangle of the neck.
The deep upper part of this muscle is the vocalis muscle.
This muscle rotates the arytenoid cartilages laterally (abduct), causing the vocal cords to separate from one another, opening the rima glottidis.
XI. Splanchnology. 1a. The Larynx. Gray, Henry. 1918. Anatomy of the Human Body. (4530 words)
In front, in the angle formed by the junction of the laminæ, are attached the stem of the epiglottis, the ventricular and vocal ligaments, the Thyreoarytænoidei, Thyreoepiglottici and Vocales muscles, and the thyroepiglottic ligament.
959, 960) is a broad, thin, muscle which lies parallel with and lateral to the vocal fold, and supports the wall of the ventricle and its appendix.
