Document Summary

* the pharynx is the area at the back end of the nasal and oral cavities and the larynx. * the phar(cid:455)(cid:374)(cid:454) is (cid:272)o(cid:373)posed of 3 differe(cid:374)t areas. The part that"s (cid:271)ehi(cid:374)d the (cid:374)asal (cid:272)a(cid:448)it(cid:455) is nasopharynx, the part that"s behind the oral cavity is the oropharyn(cid:454) a(cid:374)d the part that"s (cid:271)ehi(cid:374)d the larynx is the laryngopharynx. So, they close the posterior aspect of the nose, mouth & larynx. * the muscles have attachments onto the lateral sides of these areas (oral, nasal & larynx) and come together in the midline posteriorly. Where there is no muscle, where there are deficiencies in the muscle, there is a little bit of fascia that bridges the space and closes it off. * most of the muscles that form the sling are called constrictors and there are three constrictors: a superior constrictor, a middle constrictor and inferior constrictor.
