138 SPECIAL ANATOMY. 



c. Constrictor pharyngis superior. Inf. attach. : 1. Mucous 

 membrane of pharynx. 2. M. stylo-pharyngeus witli horizontal 

 fibres ; terminating on the thyroid cartilage covered by Constr. 

 inf. Superior attach.: \. Proc. pterygoideus-hamulus and ala 

 internet (therefore, pterygo-pharyngeus). 2. M. buccinator 

 (bucco-pharyngeus}. 3. Linea obliq. maxill. inf. (therefore, 

 mylo-pharyngeus). 4. M. genio glossus (therefore, genio- and 

 glosso-pharyngeus). Use: to press the posterior walls of the 

 pharynx together and to contract it. 



Nerves : glosso-pharyngeus and vagus. 



197. 6. Stylo-pharyngeus (s. levator pharyngis"). 



Pos. : oblique from above, downwards and inwards, between 

 m. stylo-hyoid and digastricm (behind) and m. stylo-glossus 

 (before). Externally lie, m. stylogloss., carotis externa and 

 par 'Otis ; internally, carotis intern, and V. jugular, int.; along 

 the outer side, n. glosso-pharyngeus. Or. : round, from Proc. 

 styloideus (inner surface). Ins. : between the fibres of mm. con- 

 strictor sup. and med., the last of which covers it. Use: to 

 raise and widen the pharynx above the hyoid bone. 



Nerves : glosso-pharyngeus. 



198. 7. Levator palati mollis (s. peristaphylinus internus 



s. petro-salpingo-staphylinus). 



Pos.: obliquely inwards, forwards, and downwards on the ala 

 interna of Proc. pterygoideus. Or. : the petrous bone (apex) 

 and cartilaginous portion of tuba Eustachii. Ins. : between the 

 layers of the soft palate, behind m. pharyngo-palatinus. Use : 

 to draw the velum pendulum palati upwards towards the poste- 

 rior nasal openings, by which these are contracted, and the pas- 

 sage of the fauces widened. 



199. 8. Circumjlexus s. tensor palati mollis (s. perista- 

 phylinus externus, spheno-salpingo-staphylinus). 



Pos. : close to the outer side of the last, separated by the ala 

 interna Proc. pteryg.; the tendon passes away below the Ha- 

 mul. Proc. pterygoid. inwards, at a right angle. Or. : Proc. 

 spinosus of sphenoid bone, tuba Eustachii (cartilage). Ins. : 

 before the last, with a thinner aponeurosis. Use : both draw the 

 velum-palati in a transverse direction, outwards. Whether it 

 serves this purpose, or for widening the posterior nasal openings 

 and the tuba Eustachii, is doubtful. 



200. 9. Jlzygos uvulx (s. palato-staphylinus [s. levatores 



uvuls.~]) 

 Pos. : vertical in the uvula, below the last. Or. : spina
