The cricothyroid ligament is composed of two parts: the median cricothyroid ligament along the midline (a thickening of the cricothyroid membrane). It is a flat band of white connective tissue that connects the front parts of the contiguous margins of the cricoid and thyroid cartilages. It is a thick and strong ligament, narrow above and broad ...
The cricothyroid joint (or articulation) is a joint connecting the cricoid cartilage and the thyroid cartilage. It plays a key role in adjusting human voice pitch by changing the tension of the vocal cords .
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.

Its middle thicker part is termed the median thyrohyoid ligament. [1] Its lateral thinner portions are pierced by the superior laryngeal vessels and the internal branch of the superior laryngeal nerve. [1] Its anterior surface is in relation with the thyrohyoid muscle, sternohyoid muscle, and omohyoid muscles, and with the body of the hyoid bone.

The cricotracheal ligament connects (the inferior border of) the cricoid cartilage superiorly, and the first tracheal cartilage ring inferiorly. It is continuous with the tracheal perichondrium [1] and resembles the fibrous membrane which connects the cartilaginous rings of the trachea to each other. [citation needed] Cricotracheal ligament
The procedure was first described in 1805 by Félix Vicq-d'Azyr, a French surgeon and anatomist. [3] A cricothyrotomy is generally performed by making a vertical incision on the skin of the throat just below the laryngeal prominence (Adam's apple), then making a horizontal incision in the cricothyroid membrane which lies deep to this point.
