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 ...
Type A is found in 56% of females and 66% of males. There is a well-defined "facet". It has a tight capsule and ligaments with either a concavity or a small groin directed from posterior superior to anterior inferior. Horizontal translational movement is about 3.0 mm, vertical gliding about 2.5 mm with great movement horizontally than vertically.
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. [1]
The two halves of the cartilage that make out the outer surfaces extend obliquely to cover the sides of the trachea. The posterior edge of each half articulates with the cricoid cartilage inferiorly at a joint called the cricothyroid joint. The most posterior part of the cartilage also has two projections upwards and downwards.

The cricoarytenoid joint allows for rotation and gliding motion. [1] The extent of rotation is significant, while the extent of gliding is limited.

The arytenoids are paired cartilages with a medial and a lateral process each. The medial process is called the vocal process because it is the attachment for the vocal ligament. The lateral process is the attachment of one of the major intrinsic muscles of the vocal folds and consequently named the muscular process. [1]
