class one - basics Flashcards
what is the function of the frontal lobe
excutive functioning
brocos area - expression
emtional behavior
olfaction effect
what is olfaction effect
Smell can instantly trigger an emotional response along with a memory
what is the function of the temporal lobe
hearing, lang comprehension
wrenickes area - receptive
what is the dominent hemp for language
left
what is the function of the parietal lobe
sensory loss
perceptual disorders - unilateral neglect
what is the function of the occupital lobe
visual loss
preceptual disorder associated with what side of the brain
the right side
what are the 12 CN
olfactory
occpital
oculomotor
trochlear
trigeminal
abducens
facial
vestibulorcocchlear
glossophargeal
vagus
accessory (spinal)
hypoglossal
what is the function of CN 1
smell
what is the function of CN 2
sight, peri vision, pupillary light reflex
what is the function of CN 3
eye movement - up, down, up and in
what is the function of CN 4
eye movement - down and in
what is the function of CN 5
sensation to the face
sensation to ant 2/3 of the tongue
muscle of mastication
corneal reflex
what is the corneal reflex
n involuntary blinking of the eyelids that protects the eyes from foreign objects and bright lights
what is strabismus
a condition in which one eye is turned in a direction that’s different from the other eye
CN 6
eye movement - lateral
CN 7
facial nerve
face movement
taste to ant 2/3 of the tongue
CN 8
vestibulorcochlear
hearing and balance
CN 9
glossopharngeal
gag relfex - afferent
posterior taste to the tongue
what are the two tests we use for hearing loss
rhinnes and webers test
what is the function of rinnes test
look at the type of hearing loss - sensorineral or conductive
what is the function of webers test
the side of hearing loss
how do we conduct rinnes test
using a tunning fork
The doctor places the vibrating tuning fork on the patient’s mastoid bone behind their ear
The doctor asks the patient to indicate when they can no longer hear the sound
The doctor quickly moves the tuning fork next to the patient’s ear
The doctor asks the patient to indicate when they can no longer hear the sound
rinnes test normal hearing
Normal hearing: Air conduction is heard twice as long as bone conduction
rinnes test Conductive hearing loss
Bone conduction is heard longer than or as long as air conduction
rinnes test Sensorineural deafness:
Air conduction is better than bone conduction
what is webers test
Strike a 512 Hz tuning fork on a surface like a palm
Place the vibrating tuning fork on the middle of the patient’s head
Ask the patient if they hear the sound in one ear or both ears equally
weber’s test: normal
In a person with normal hearing, the sound will be heard in the center of the head or equally in both ears.
weber’s test: conductive
If the patient has conductive hearing loss, the sound may be heard in the poorer hearing ear.
weber’s test: Sensorineural Loss
Hearing loss, the sound will be heard on the side of the better hearing ear.
what is the cheat for weber’s test to remember it
Use CANS for Weber’s :
- Conductive——— Louder to AFFECTED ear
- Sensorineural —– Louder in NORMAL ear
CN 10
gag refleex - efferent
what is anosmia
full or partial loss of smell
the frontal lobe is effected of CN1
what is myopia
you can see objects that are near clearly but have difficulty seeing objects that are farther away
what is presbyopia
A gradual, age-related loss of the eyes’ ability to focus actively on nearby objects.
what is the pathway for the pullilary light relfex
shine light in right eye
R cranial nerve 2 tells CN 3 R/L to constrict the eyes
if CN 3 is effected what kind of strabismus would you see
lateral
if the abducen CN is effected what strabismus would we expect
medial
what CN opens the the eye
CN 3
what CN closes the eye
CN 7
what is sensorineural hearing loss
type of hearing loss that occurs when the inner ear or auditory nerve is damaged
what is conductive hearing loss
sounds cannot get through the outer and middle ear. It may be hard to hear soft sounds. Louder sounds may be muffled.
plug your ears
what ghe right CN 10 in effected what side does the uvla go
the left side
what is the order of the brain stem
midbrain
pons
medulla
what does
CE
MI
PONS
MEDU
cerebrum - 1,2
midbrains - 3,4
PONs - 5,6,7,8
medulla - 9,10,11,12
is someone has pstosis what nerve is affected
CN 3
this opens our eye s
what CN is responsible for the corneal reflex
trigemenial - afferent, sense the stimulus
facial - efferent, performs closing
what CN help dampen the sound
CN 5 and 7
what CN help with gag relfex
gloss (9) - afferent, sensation
vagus (10) - efferent, produceds action
what happens to the tongue if CN X11 is affected
tongue goes towards the weak side
what CN closes the eye
CN 7 - 7 pm is closing time
