Topic: Superior pharyngeal constrictor muscle

	Morphological study of the superior pharyngeal constrictor muscle
		Objectives: To clarify the details morphology of the superior pharyngeal constrictor muscle in humans during ingestion movement, we examined the macroscopic characteristics of the pterygopharyngeal, buccopharyngeal, mylopharyngeal and glossopharyngeal parts of the muscle.
		Results: The superior pharyngeal constrictor muscle at the pterygopharyngeal part originated between the pterygoid hamulus of the sphenoid bone and the posterior margin of the medial pterygoid plate to form the most superior area of the pharyngeal wall.
		Morphology of the origin of the muscle at the mylopharyngeal part could be divided into two types: type I, tip of the origin of the muscle on the mylohyoid line; and type II, tip of the origin of the muscle away from the mylohyoid line.

		Tensor veli palatini: This muscle arises from the scaphoid fossa, spine of the sphenoid, and the cartilaginous portion of the eustachian tube.
		The ostium is bordered anteriorly by the salpingopalatine fold and posteriorly by the cartilaginous torus tubarius.
		Posterior to the torus tubarius is the pharyngeal recess.

		The superior pharyngeal constrictor muscle [cross-section] attaches to the lower part of the posterior border of the medial pterygoid plate, to the pterygomandibular raphe, to the highest part of the mylohyoid line on the inner surface of the mandible, and to the root of the tongue between the genioglossus and hyoglossus muscles.
		The inferior portion of the superior constrictor muscle is overlapped superficially by the fibers of the middle pharyngeal constrictor muscle.
		The superior and lateral aspect of the pharyngeal wall is devoid of muscle fibers and is formed only by a thickening of the pharyngobasilar fascia.

	Mastication - Wikipedia, the free encyclopedia
		Mastication is chiefly possible thanks to powerful muscles, masseter and temporalis, as well as smaller muscles that allow fine control.
		Chewing food is a complex technique, muscles need to be powerful enough to break tough portions of food, yet have enough dexterity to not injure the tongue, and to clear the mouth completely.
		Temporalis is a muscle attached to the temporal fossa (on the side of the skull) and connects to the coronoid process of the mandible.

	Parapharyngeal Space Neoplasms
		The inferior limit of the PPS is represented by the junction of the posterior belly of the digastric muscle and the greater cornu of the hyoid bone.
		The lateral wall of the PPS is formed by, from anterior to posterior, the medial pterygoid fascia, ramus of the mandible, retromandibular portion of the deep lobe of the parotid, and the posterior belly of the digastric muscle.
		Ectopic rests of salivary tissue may be located lateral to the superior pharyngeal constrictor muscle or may arise medial to the muscle from the mucosa of the pharynx.

	Thickness and histologic and histochemical properties of the superior pharyngeal constrictor muscle in velocardiofacial ...
		Thickness and histologic and histochemical properties of the superior pharyngeal constrictor muscle in velocardiofacial syndrome.
		The histologic and histochemical properties of the SPC muscle in 9 VCFS patients (6 male and 3 female; age range, 4-12 years) were compared with SPC muscle in 3 adult cadavers without VCFS (all male; age range, 80-86 years) using specimens obtained during pharyngeal flap surgery.
		The SPC muscle contained a significantly greater proportion of type 1 fibers in patients with VCFS (27.7%) than in adults without VCFS (17.9%), and the diameter of the type 1 fibers was significantly smaller in patients with VCFS (21.6 micro m) than in adults without VCFS (26.6 micro m).

	Physiology of the Swallow
		The pharyngeal phase of the swallow is involuntary.
		The velum is raised, primarily by the levator and tensor veli palatini muscles.
		The elevation of the larynx may pull the muscle upward, causing it to open by stretching it and therefore causing it to relax.

	The Voice & Swallowing Center
		Medial contraction of the lateral pharyngeal wall musculature in combination with slight anterior movement of the posterior pharyngeal wall creates Passavant's ridge, which is a ridge of tissue against which the velum is approximated during the first portion of the pharyngeal phase of swallowing (21, 22).
		This anterior movement of the larynx combined with the contraction of the middle and inferior constrictor muscles strips the food bolus inferiorly, ushering in the final portion of the pharyngeal phase which is entry of the food bolus into the cervical esophagus.
		The brainstem is responsible for the involuntary (pharyngeal and esophageal) phases of swallowing.

		The external laryngeal nerve, smaller than the internal, descends posterior to the sternothyroid with the superior thyroid artery but on a deeper plane; it lies at first on the inferior pharyngeal constrictor and then, piercing it, curves round the inferior thyroid tubercle to reach and supply the cricothyroid.
		It also supplies the pharyngeal plexus and inferior constrictor; behind the common carotid artery it connects with the superior cardiac nerve and superior cervical sympathetic ganglion.
		Near its beginning the facial vein connects with the superior ophthalmic directly and via the supraorbital; it is thus connected to the cavernous sinus.

	Dysphagia
		Lateral pharyngeal pouches are transient or persistent protrusions of the upper lateral pharyngeal wall in an area of weakness of the unsupported thyrohyoid membrane.
		The Mendelsohn maneuver is performed by voluntarily elevating the larynx during the swallow, which tucks the laryngeal inlet anteriorly and opens the PE segments, thereby facilitating the swallow.
		Patients with unilateral pharyngeal paralysis can turn their head towards the paralyzed side, which diverts the bolus down the functioning side of the pharynx.
