    1 Genio-hyoid: inferior genial tubercle on posterior surface of inferior maxilla near symphysis(T)—middle of body of hyoid bone(F) (ist and 2nd cervical). [Raises and draws forward hyoid.] \ LINGUAL REGION. Genio-hyo-glossus: superior genial tubercle on posterior surface of inferior maxjlla near symphysis(t)—body of hyoid bone(F) (posterior fibres): inferior surface of tongue from root to tip(F) (anterior fibres) (Hypoglossal). [Raises tongue and hyoid bone, draws tongue forwards and protrudes it to opposite side.] 4 Hyo-glossus: side of body, from all great cornu of hyoid and from smaller cornu(F)—back and side of tongue(F) (Hypo- glossal). [Depresses sides of tongue, making surface convex laterally.] Parts beneath hyo-glossus : inferior lingualis, genio-hyo-glossKS and middle constrictor muscles, lingual vessels, stylo-hyoid ligament, glosso-pharyngeal nerve. S^ Stylo-glossus: external surface of apex of styloid process and stylo-maxillary ligament(A)—dorsum and tip of tongue(F) (Hypoglossal). [Draws tongue upwards and backwards, makes superior surface concave laterally.] PHARYNGEAL REGION. Inferior constrictor: side of cricoid cartilage; oblique line on thyroid and surface behind it, inferior cornu of thyroid cartiiage(F) — fibrous raphe in posterior median line of pharynx(F) (Pharyngeal plexus, External laryngeal. Re- current laryngeal). [Squeezes food towards oesophagus in swallowing, jj Middle constrictor : great and small cornua of hyoid bone, stylo-hyoid ligament(F)—fibrous raphe in posterior median line of pharynx(F) (Pharyngeal plexus). [Squeezes food towards oesophagus in swallowing,] Superior laryngeal vessels and internal laryngeal nerve pass between this muscle and the inferior, near origin. Superior constrictor: lower 3rd of posterior margin of in- ternal pterygoid plate, hamular process, pterygo-maxillary ligament, posterior part of mylo-hyoid ridge of inferior maxilla, mucous membrane of mouth and side of tongue(F) —fibrous raphe in posterior median line of pharynx(F), and pharyngeal spine on basilar process(F) (Pharyngeal plexus).
