muscles
Palatoglossus attachment, action and innervation
Attachment: between the soft palate and the tongue, Depresses soft palate, CN X
3 salivary glands
parotid, submandibular, sublingual
function of sinus
•Lighten the skull
•Resonate the voice
Produce mucus
fxn of conjunctiva
provides protection and lubrication of the eye by the production of mucus and tears
what CN innervates ear
CN VIII
Mylohyoid OIAI
O:Mylohyoid line of mandible
I:body of hyoid bone
A:elevates hyoid bone and floor of mouth, depresses mandible
I: CN V-3
which 3 cranial nerves provide sensory info to tongue
VII,- taste- anterior 2/3
IX, sensory and taste- post 1/3
X-taste-larynx
4 paranasal sinuses
frontal, maxillary, ethmoid, sphenoid
MOST eye muscles are innervated by what CN
CN 3
name all middle ear infection information you can think of
•common in kids bc Auditory tube is short and horizontal
fluid accumulates in tympanic cavity
can spread to meningitis and hearing loss
palatopharyngeus O,I,A,I
O:Palatine aponeurosis and hard palate
I:Upper border of thyroid cartilage
A: pulls pharynx and larynx up
I: CN X
5 tastes:
Salty
•Sweet
•Sour
•Bitter
•Umami
3 CN that innervate nasal cavity
CN I, V, VII
what are the exceptions to that ^ and what is the CN
superior oblique- CN IV
lateral rectus- CN VI
contents of middle ear
Malleus (Tensor tympani M) – Incus – Stapes – Oval Window
Levator Veli Palatini O,I,A,I
O: temporal bone, auditory tube
I: palatine aponeurosis
A:elevates soft palate during swallowing
I: CN X
NOT MOUTH BUT EAR
what is the role of the auditory tube
keep pressure stabilized, drainage of secretions from middle ear into nasopharynx
structure that frontal and maxillary sinus use to drain through
hiatus semilunaris
what glands lubricates and moistens
lacrimal gland
what is the role of ossicles
transmit sounds from the air to the fluid-filled labyrinth (cochlea)
Random: what CN provides parasympathetic innervation to glands
CN VII
NOT MOUTH BUT EAR:
Saccule and Utricle fxn
use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation; let you know where in space you are
which CNs (be specific) provide sensation to nasal cavity
CN V
V-1- sensation of superior aspect
V-2- remaining sensation
3 events of seeing near
1.convergence-Eyes orient their visual axis toward object
2.constriction- Blocks peripheral light rays and reduces spherical aberration
3. accommodation-
what are the semicircular ducts functions
rotary movements, sensory organ of balance
where vertigo comes from
