VISCERAL ANATOMY. 



the mucous lining of the pharynx, Eustachian tube, tympanum and mastoid 

 cells; also with that of the frontal ,<* ethmoid al and sphenoidal sinuses/ the 

 antrum, nasal duct, and the conjunctiva. It is covered with columnar epithe- 

 lium, ciliated throughout most of its extent, provided with mucous glands, and in 

 FlG _ its deeper layer with the 



d Olfactory Cells of Schultze, 



spindle - shaped, epi- 

 thelial structures grouped 

 around and between the 

 columnar epithelial cells, 

 and joined together by 

 their anastomosing pro- 

 cesses, to form an intri- 

 cate plexus on which the 

 terminal fibres of the ol- 

 . factory nerve are sup- 

 posed to be distributed. 



Name the Arteries of the Nose. They are the 

 Lateralis Nasi, branch of the facial, to the alae of the nose. 

 Nasal of the Septum* from the superior coronary artery, to the septum. 

 Nasal, branches of the ophthalmic and infra- orbital, to the dorsum and sides 



of the nose. 



Name the Arteries of the Nasal Fossae. They are the 

 Anterior and Posterior Ethmoidal, from the ophthalmic. 

 Spheno-palatine, branch of the internal maxillary. 

 Alveolar, branch of the internal maxillary, to the antrum. 



What Nerves supply the Nose ? Branches from the facial, infra- 

 orbital and infra-trochlear, and a filament from the nasal branch of the 

 ophthalmic nerve. 



What Nerves supply the Nasal Fossae ? They are the 

 Olfactory or ist Cranial,* over the upper third of the septum nasi, and over 



the superior and middle turbinated bones. 



Nasal Branch of the Ophthalmic, g to the septum and outer walls. 

 Anterior Dental Branch of the Superior Maxillary, j to the inferior meatus 



of the nose and the inferior turbinated bone. 

 Spheno-palatine Ganglion, sends branches to the septum and the superior 



turbinated bone, the Superior Nasal Br. to the same parts, the Naso- 



palatine to the middle of the septum, and the Anterior Palatine to the 



middle and lower turbinated bones.
