pharyngeal aponeurosis

Laterally it is continuous with the pharyngeal aponeurosis.

The pharyngeal aponeurosis (or pharyngobasilar fascia, or fibrous coat), is situated between the mucous and muscular layers.

The pharyngeal aponeurosis is attached to the entire length of the posterior edge of the medial plate, and the Constrictor pharyngis superior takes origin from its lower third.

In the pharynx, the sinus of Morgagni is the enclosed space between the upper border of the superior pharyngeal constrictor muscle, the base of the skull and the pharyngeal aponeurosis.
