Week 2 Wet Flashcards
3 cranial fossa
anterior, middle and posterior
bones of anterior fossa floor
frontal, ethmoid and sphenoid
bones of middle fossa floor
sphenoid and temporal
bones of posterior fossa floor
temporal and occipital
which bone do the nasal bones articulate with superiorly
frontal
bones which form the nasal septum
vomer inferiorly and perpendicular plate of ethmoid superiorly
bones that make the floor of nasal cavity
maxillary and palatine
bone of inferior concha
it is a bone by itself
bone of superior and middle concha
ethmoid bone
what sinus sits right behind the nasal cavity
sphenoid sinus
what is the crista gali
a prominence of the ethmoid bone which points superiorly
what kind of epithelium lines the nasal cavity
ciliated pseudostratified squamous
spaces inbetween concha from inf to sup
inferior meatus
middle meatus
superior meatus
spheno-ethmoidal recess
artery of the nose
opthalmic artery
what neck artery is the opthalmic artery a branch of
internal carotid
which sinus is most vulnerable to infections and why
maxillary - it drains from its superior aspect so has residual content
4 paranasal sinuses
frontal, maxillary, ethmoidal air cells and sphenoid
meatus that sphenoid sinus is connected to
spheno-ethmoidal recess
meatus(es) that ethmoidal air cells open into
superior (just posterior air cells) and middle
what drains into the inferior meatus
nasolacrimal duct
which air sinuses floor is indented by teeth
maxillary
innervation of air sinuses
frontal - V1
ethmoidal air cells - V1
sphenoid - V1 and V2
maxillary - V2
remember FESM
what bone forms the roof of the nasopharynx
sphenoid
what bone form the roof of the nasal cavity
ethmoid and sphenoid at the back
where are the adenoids
beneath the epithelium of roof and posterior wall of nasopharynx
what are adenoids
aka nasopharyngeal tonsils. They are collections of lymphoid tissue
muscle that attaches to the nasopharynx opening of eustachian tube
salpingopharyngeus
when are adenoids most prominent
in childhood
which part of the ear does the eustachian tube connect to
middle ear (where the ossicles are)
