16
Q

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

A

middle meatus

17
Q

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

A

frontonasal duct

18
Q

this structure is the drainage point of the sphenoid sinus?

A

sphenoethmoidal recess

19
Q

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?

A

hiatus semilunaris

20
Q

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

A

nasolacrimal canal

21
Q

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

A

auditory tube

22
Q

this structure of the nasal cavity has hair like air filters at the nostril entrance?

A

vibrisae

23
Q

what are the three structures that make up the nasal septum?

A

nasal septum cartilage
vomer bone
perpendicular plate of the ethmoid bone

24
Q

what is the cell type of the nasal cavity?

A

pseudo stratified ciliated columnar epithelium that filters, moistens, and humidifies

25
Q

what is the blood supply of the nasal cavity?

A

maxillary a. branches

26
Q

what are the muscles of the posterior pharyngeal wall?

A

constrictor muscles
longitudinal muscles
tensor palatini m
levator palatini m

27
Q

what are the constrictor muscles? what are the innervations?

A

superior (CN 9/10), middle (CN 9/10) and inferior (CN X) pharyngeal constrictor muscles

28
Q

what are the longitudinal muscles? innervations? what bump is found at the very top of the salpingopharyngeus m.

A 
salpingopharyngeus m (CN X)
palatopharyngeus m (CN X)
stylopharyngeus m (CN IX)

taurus tuberus

29
Q

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?

A

tensor palatini

V3

30
Q

this muscle of the posterior pharyngeal wall elevates the soft palate and uvula; runs more vertically; what is this innervation?

A

levator palatini m

CN IX and X, the pharyngeal plexus

31
Q

what are the lymphoid structures found in the nasal cavity and pharynx? be specific

A

tonsils

pharyngeal tonsil
palatine tonsil
lingual tonsil

32
Q

this tonsil lies between the palatoglossal and palatopharyngeal mm?

A

palatine tonsil
