Definitions of CONSTRICTORES PHARYNGIS
Sort: Oldest first
Constrictors of the Pharynx, Sphincter Gulae. Muscular expansions which assist in forming the parietes of the pharynx. Three of these are generally admitted. 1. The Constrictor Pharyngis inferior, Cricopharyngeus and Thyro-pharyngeus,and Thyro-pharngeus, (F.) Cricothyro-pharyngien. It is broad, very thin, quadrilateral seated superficially, extending form the thyroid and cricoid cartilages as far as the middle of the pharynx, and uniting, on the median line, with that of the opposite side. 2. The Constrictor Pharyngis Medius, Hyo-pharyngeus and Chondro-pharyngeus, Syndesmo -pharyngeus (F.) Hyoglosso-basi-pharyngien. occupies the middle part of the pharynx. It is a triangular, and attached anterioly to the great and little cornu of the os hyoides; to the stylohoid ligament; and terminates, posteriorly, by joining its fellow of the opposite side. 3. The Constrictor Pharyngis superior, Cephalo-pharyngeus, Glosso-pharyngeus, Mylo-pharyngeus, Pterygo-pharyngeus, (F.) Pterygo-syndesmo-staphili-pharyngien,is quadilateral, and extends from the internal ala of the pterygoid process from the inter- maxillary ligament, from the internal oblique line of the jaw, and from the base of the tongue to the posterior part of the pharynx. The constrictors of the pharynx contract it. They can like wise approximate the ends to each other. Chaussier considers those and the stylopharyngeus as but one muscle, and includes all under this last name.
