The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the medial pterygoid muscle and the medial surface of the ramus of the mandible .
The pterygomandibular ligaments are marked with arrows. Note that in this mouth the lower wisdom teeth have been removed, slightly changing the shape of the pterygomandibular ligaments that usually curve and attach to the mandible around them. The pterygomandibular raphe is a tendinous band [2] [3] formed by the buccopharyngeal fascia.

The posterior (back) part of this line, near the alveolar margin, gives attachment to a small part of the superior pharyngeal constrictor muscle, and to the pterygomandibular raphe. Function [ edit ]
Human anatomy is the scientific study of the morphology of the adult human. It is subdivided into gross anatomy and microscopic anatomy . Gross anatomy (also called topographical anatomy, regional anatomy, or anthropotomy) is the study of anatomical structures that can be seen by unaided vision.
The buccopharyngeal fascia is a thin lamina given off from the pretracheal fascia. [citation needed] It is the portion of the pretracheal fascia situated posterior and lateral to the pharynx.

Two constants, found in nearly all insect wings, are the claval (a flexion line) and jugal folds (or fold line), forming variable and unsatisfactory boundaries. Wing folding can be very complicated, with transverse folding occurring in the hindwings of Dermaptera and Coleoptera, and in some insects, the anal area can be folded like a fan.
