The pterygomandibular raphe (pterygomandibular fold[1] or pterygomandibular ligament) is a thin [2] tendinous band of buccopharyngeal fascia. It is attached superiorly to the pterygoid hamulus of the medial pterygoid plate, and inferiorly to the posterior end of the mylohyoid line of the mandible. It gives attachment to the buccinator muscle ...
The superior pharyngeal constrictor muscle is a quadrilateral muscle of the pharynx. It is the uppermost and thinnest of the three pharyngeal constrictors. [citation needed] The muscle is divided into four parts according to its four distincts origins: a pterygopharyngeal, buccopharyngeal, mylopharyngeal, and a glossopharyngeal part.
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 lateral pterygoid muscle and the medial surface of the ramus of the mandible. The pterygomandibular space is one of the four ...
Sagittal section of skull. (Sphenoid is in yellow, and pterygoid hamulus labeled at bottom center.) The pterygoid hamulus is a hook-like process at the lower extremity of the medial pterygoid plate of the sphenoid bone of the skull. It is the superior origin of the pterygomandibular raphe, and the levator veli palatini muscle.
The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
Pharyngeal raphe. Muscles of the pharynx, viewed from behind, together with the associated vessels and nerves. (Pharyngeal raphe not labeled, but region is visible.) The pharyngeal raphe is a raphe that serves as the posterior attachment for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor ...
The pharyngobasilar fascia is a fascia of the pharynx. [1] It is situated between the mucous and muscular layers of the pharynx. [citation needed] It is formed as a thickening of the pharyngeal mucosa superior to the superior pharyngeal constrictor muscle. It attaches to the basilar part of occipital bone, the petrous part of the temporal bone ...
It is the portion of the pretracheal fascia situated posterior and lateral to the pharynx. It encloses the entire superior part of the alimentary canal. [3] The buccopharyngeal fascia envelops the superior pharyngeal constrictor muscles. [4][1] It extends anteriorly from the constrictor pharyngis superior [4] over the pterygomandibular raphe to ...
