	Pharynx - Wikipedia, the free encyclopedia
		Pharynx is the part of the neck and throat just behind the mouth and nose.
		It is situated immediately posterior to the mouth and nasal cavity, and is cranial to the esophagus, larynx, and trachea.
		Because both food and air pass through the pharynx, special adaptations are necessary to prevent choking or aspiration when food or liquid is swallowed.

		It is a musculomembranous tube, somewhat conical in form, with the base upward, and the apex downward, extending from the under surface of the skull to the level of the cricoid cartilage in front, and that of the sixth cervical vertebra behind.
		As soon as the bolus of food is received in the pharynx, the elevator muscles relax, the pharynx descends, and the Constrictores contract upon the bolus, and convey it downward into the esophagus.
		In the nasal part of the pharynx it is covered by columnar ciliated epithelium; in the oral and laryngeal portions the epithelium is stratified squamous.

		The oral pharynx communicates with the naso-pharynx by the pharyngeal isthmus behind the free edge of the soft palate.
		Above and in front it is continuous with the cavity of the mouth, and the demarcation between the two is a ridge of mucous membrane on each side running from the soft palate to the side of the tongue, and caused by the projection of the palato-glossus muscle.
		Below this the pharynx narrows rapidly until the level of the lower border of the cricoid cartitape in front and of the sixth cervical vertebra behind is reached; here it passes into the oesophagus, having reached a total length of about five inches.

		The constrictors of the pharynx have their fixed points in the anterior larynx, where they are attached to bones or cartilages, whereas they expand posteriorly, overlap one another from inferior to superior, and end in a median tendinous raphe in the posterior midline.
		The pharyngeal ridge is an elevation or bar on the posterior wall of the pharynx inferior to the level of the soft palate; it is produced during swallowing by transverse muscle fibers.
		The epiglottis is attached by ligaments to the hyoid bone, to the posterior aspect of the tongue, to the sides of the pharynx, and to the thyroid cartilage.

		The PHARYNX is a fibromuscular tube which extends from the base of the skull to the lower border of the cricoid cartilage (at which point it becomes the esophagus).
		Portions of the pharynx lie posterior to the nasal cavity (nasal pharynx), oral cavity (oral pharynx) and larynx (laryngeal pharynx).
		First, the larynx is raised, along with the pharynx, by the contraction of the longitudinal muscles of the pharynx.

		PHARYNX [pharynx], area of the gastrointestinal and respiratory tracts which lies between the mouth and the esophagus.
		At its upper end, it is continuous with the mouth and nasal passages, and connects with the ears via the Eustachian tubes.
		In humans, the pharynx is particularly important as an instrument of speech: it functions with the various parts of the mouth to articulate the initial sounds produced in the larynx.

		The nematode pharynx has been used widely as the basis for the taxonomy of these animals, because nuclei, organized in well-defined and constant arrays were easily visualized by light microscopists.
		Somatic sensory input to the pharynx is primarily through a set of anterior sensilla, the inner labials.
		To act as a rescue mechanism, the proprioreceptive endings of I1 would have to detect the open state of the pharynx and by means of the connection to M2 stimulate the isthmus to contract and pass food back to the terminal bulb.

		The walls of the pharynx contain muscles that play a major role in swallowing, gagging, and vomiting, and also are important for phonation, respiration, coughing, and sneezing.
		The muscles of the pharynx are the superior (SPC), middle (MPC), and inferior (IPC) pharyngeal constrictors and the paired stylopharyngeus, salpingopharyngeus, and palatopharyngeus muscles.
		The motor nerves to the pharynx combine to form the pharyngeal plexus which in turn supplies the terminal motor branches to pharyngeal structures.
