Anatomy Exam 2 - Nasal Cavity And Paranasal Sinuses

Front 1

roof of the nose is made up of

Back 1

-cribiform plate (ethmoid bone)
-nasal bones
-maxilla and frontal bones
-nasal cartilages

Front 2

the nasal septum consists of

Back 2

-vomer
-perpendicular plate of the ethmoid
-septal cartilage

Front 3

the floor of the nose consists of

Back 3

-hard palate
-palatine processes of maxilla
-palatine bone
-incisive foramen
-greater and lesser palatine foramina

Front 4

lateral wall of the nose consists of

Back 4

conchae
-inferior concha (separate bone)
-middle concha (part of ethmoid)
-superior concha (part of ethmoid)
-meatus (space below each concha)

Front 5

arteries of the nose

Back 5

-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)

Front 6

veins of the submucosal plexus drain into

Back 6

-sphenopalatine v (eventually maxillary v)
-facial v
-opthalmic v

Front 7

nerves of the nose

Back 7

-olfactory n (CN I)
-nasopalatine (branch of maxillary)
-greater palatine (maxillary branch of CN V)
-lesser palatine (maxillary branch of CN V)
-pterygopalatine ganglion

Front 8

olfactory nerve function

Back 8

special sensations (smell) to the olfactory mucosa

Front 9

nasopalatine n function

Back 9

sensory to the nasal septum and anterior part of the hard palate

Front 10

greater palatine function

Back 10

sensory to the hard palate

Front 11

lesser palatine n function

Back 11

sensory to the soft palate

Front 12

pterygopalatine ganglion function

Back 12

parasympathetic ganglion
-branches of maxillary nerve pass through ganglion
-preganglionic parasympathetic fibers from CN VII terminate here

Front 13

air filled chambers that communicate with the nose
-resonating chambers for sound quality

-located in the sphenoid bone
-opens into the sphenoethmoidal recess (above superior concha)

Front 18

ethmoidal air cells location and opening

Back 18

-located in the ethmoid bone
-anterior and middle groups open into the middle meatus\
-posterior group opens into the superior meatus
