roof of the nose is made up of
|
-cribiform plate (ethmoid bone)
-nasal bones -maxilla and frontal bones -nasal cartilages |
|
the nasal septum consists of
|
-vomer
-perpendicular plate of the ethmoid -septal cartilage |
|
the floor of the nose consists of
|
-hard palate
-palatine processes of maxilla -palatine bone -incisive foramen -greater and lesser palatine foramina |
|
lateral wall of the nose consists of
|
conchae
-inferior concha (separate bone) -middle concha (part of ethmoid) -superior concha (part of ethmoid) -meatus (space below each concha) |
|
arteries of the nose
|
-anterior ethmoidal a (from opthalmic a)
-posterior ethmoidal a (from opthalmic a) -sphenopalatine a (from maxillary a) -grater palatine a (from descending palatine branch of maxillary a) -superior labial a (from facial a) |
|
veins of the submucosal plexus drain into
|
-sphenopalatine v (eventually maxillary v)
-facial v -opthalmic v |
|
nerves of the nose
|
-olfactory n (CN I)
-nasopalatine (branch of maxillary) -greater palatine (maxillary branch of CN V) -lesser palatine (maxillary branch of CN V) -pterygopalatine ganglion |
|
olfactory nerve function
|
special sensations (smell) to the olfactory mucosa
|
|
nasopalatine n function
|
sensory to the nasal septum and anterior part of the hard palate
|
|
greater palatine function
|
sensory to the hard palate
|
|
lesser palatine n function

sensory to the soft palate
|
|
pterygopalatine ganglion function
|
parasympathetic ganglion
-branches of maxillary nerve pass through ganglion -preganglionic parasympathetic fibers from CN VII terminate here |
|
air filled chambers that communicate with the nose

|
ethmoidal air cells location and opening
|
-located in the ethmoid bone
-anterior and middle groups open into the middle meatus\ -posterior group opens into the superior meatus |
