Therefore, it is extremely important in upper body extremity movement and can cause significant pain to patients presenting with radial tunnel syndrome. [4] Unlike carpal tunnel syndrome, radial tunnel syndrome does not present tingling or numbness, since the posterior interosseous nerve mainly affects motor function. [5]
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 cover the buccinator muscle [ 1 ] (though another source describes it as continuous with the fascia covering the buccinator muscle).
[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 (medial to the pharyngotympanic tube), the (posterior border of the) medial pterygoid plate, and the pterygomandibular raphe. It ...
Its posterior border gives attachment to the superior pharyngeal constrictor muscle. [3] Its anterior border attaches to the posterior edge of the buccinator muscle. [3] The pterygomandibular raphe is the common meeting point of the superior pharyngeal constrictor muscle and the buccinator muscle. This common attachment makes the raphe a ...
Passing laterally and downward behind the palatine tonsil, the palatopharyngeus joins the stylopharyngeus and is inserted with that muscle into the posterior border of the thyroid cartilage, some of its fibers being lost on the side of the pharynx and others passing across the middle line posteriorly to decussate with the muscle of the opposite ...
The interval between the upper border of the muscle and the base of the skull is closed by the pharyngeal aponeurosis, and is known as the sinus of Morgagni. [2] There is an interval between superior pharyngeal constrictor and middle pharyngeal constrictor, this space contains glossopharyngeal nerve, lingual nerve and the stylopharyngeus muscle ...
The danger space serves as an important pathway for complicated infections of the posterior pharynx to enter the chest and spinal column. Anterior to the parapharyngeal space is the masticator space which contains the lower dental row, muscles of mastication, the inferior alveolar nerve as well as branches of cranial nerve V.
The posterior pharyngeal part is the part closest to the throat, roughly one-third of its length. These parts differ in terms of their embryological development and nerve supply. The anterior tongue is, at its apex, thin and narrow. It is directed forward against the lingual surfaces of the lower incisor teeth.
