Answer 5

nasal sinuses

Question 6

what are the 4 different nasal air sinuses?

Answer 6

frontal sinus
maxillary sinus
sphenoid sinus
ethmoid air cells

Question 7

this is the sinus found in the forehead; drains through frontonasal duct into middle meatus

Answer 7

frontal sinus

Question 8

this is the largest sinus; drains through hiatus semilunaris into middle meatus?

Answer 8

maxillary sinus

Question 9

this sinus drains through sphenoethmoidal recess into superior meatus?

Answer 9

sphenoid sinus

Question 10

this sinus is found under the middle meatus?

Answer 10

ethmoid air cells

Question 11

what are the contents of the nasal cavity?

Answer 11

concha
meatus
auditory tube
vibrisae
nasal septum
palate
pterygomandibular raphe
vocal folds

Question 12

these concha are part of the ethmoid bone?

Question 14

this is the space underneath the concha? how are these divided up?

Answer 14

meatus

superior meatus
middle meatus
inferior meatus

Question 15

what structure is found in the superior meatus?

Answer 15

sphenoethmoidal recess

Question 16

the ethmoid bulla, hiatus semilunaris, anterior and posterior ethmoidal air cells, and frontonasal duct are the structures found in which meatus?

Answer 16

middle meatus

Question 17

this duct drains the frontal sinus and anterior ethmoidal air cells into the middle meatus?

Answer 17

frontonasal duct

Question 18

this structure is the drainage point of the sphenoid sinus?

Answer 18

sphenoethmoidal recess

Question 19

this structure found in the middle meatus is the drainage point of the maxillary sinus into the middle meatus; semilunar shape because of the ethmoid bulla?

Answer 19

hiatus semilunaris

Question 20

this structure is found in the inferior meatus and drains into nasal chamber at this meatus?

Answer 20

nasolacrimal canal

Question 21

this is a content of the nasal cavity that is a cartilaginous tube that extends from nasopharynx to the ear, it equilibrates pressure around the tympanic membrane so it can vibrate? this is why we have sinus infections

Answer 21

auditory tube

Question 29

this muscle of the posterior pharyngeal wall tenses the soft palate and pulls the auditory tube open creating a hinge like apparatus, allows the levator palatini to lift the soft palate right behind the lateral ptyergoid plate and develops from the first Branchial arch; what is the innervation?

Answer 29

tensor palatini V3
