Dissection of nasal fossae, nasal pharynx, and palate
Relation of nasal septum to sphenoid sinus and hypophysis; right palatine nerves; palatine arches, left lateral view
The cartilage and bones of the nasal septum have been cut away so that the mucous membrane which covered the right side of the septum is exposed. The sphenoid sinus has been widely opened and a window cut in its bony roof to expose the hypophysis. The left internal carotid artery has been retracted posteriorly.
1 . Upper pointer: Medial wall of orbit Lower pointer: Anterior ethmoidal foramen
2 . Bony roof of ethmoidal cell
3 . Olfactory bulb (visible through window in ethmoidal air cell)
4 . Olfactory nerve (I) (enclosed in fibrous sheaths; upper pointer indicates filaments which pass to left lateral wall, lower pointer those which pass to right side of septum)
5 . Margin of septal cartilage
6 . Mucosal membrane septi (attached surface)
7 . Nasopalatine nerve left (cut away centrally)
8 . Terminal branches of nasopalatine nerve and sphenopalatine artery (posterior septal artery) entering incisive canal
9 . Incisive canal
10 . Anterior palatine nerve emerging from greater palatine foramen
11 . Ostium of parotid duct
12 . Optic nerve (II) (cut off in optic canal)
13 . Internal carotid artery (retracted posteriorly)
14 . Hypophysis
15 . Sphenoid sinus
16 . Rostrum of sphenoid
17 . Posterior nasal septal arteries right
18 . Nasopalatine nerve right
19 . Pharyngeal tonsil
20 . Nasal septum
21 . Upper pointer: Torus tubarius Lower pointer: Pharyngeal recess
22 . Posterior palatine nerve
23 . Middle palatine nerve
24 . Soft palate (pointer on fibers of uvular muscle)
25 . Pharyngopalatine muscle (in palatopharyngeal arch)
26 . Upper pointer: Palatine tonsil Lower pointer: Glossopalatine muscle (in palatoglossal arch)
