Abstract
In a study of the anatomy of this region it is usual to consider thyropharyngeus and cricopharyngeus muscles as the two parts of the inferior constrictor of the pharynx, although there is doubt whether the upper part of this muscle plays any part in the mechanism of the cricopharyngeal sphincter. The thyropharyngeus muscle arises from the oblique line of the thyroid cartilage, from a strip of the surface behind this line and from a fine tendinous band which is thrown across the cricothyroid muscle from the inferior thyroid tubercle to the cricoid cartilage. In addition, there is a small slip of muscle arising from the inferior cornu of the thyroid. Its fibres spread backwards and medially to be inserted with the muscle of the opposite side into a fibrous raphe in the midline of the posterior wall of the pharynx. The lower fibres are thinned out and lack the support of the underlying middle and superior constrictor muscles below the level of the vocal cords.
