Cards

Term
abducens VI
Definition

helps eyes to "aduct" move out

Lateral movement of eye

motor=1 extra occular muscle (lateral rectus)

problem w/ this would cause eye to turn inward (esotropia/crossed eyes)

 

Term
accessory XI
Definition

motor= sternoclaidomastoid  and trapezius

Prob: weakness in turning head toward opposite side

Term
facial VII
Definition

 

Mixed nerve
§Motor functions stapedius muscle, muscles of facial expressions, lacrimal glands, salivary glands
§Sensory function is taste from the anterior 2/3 of the tongue, skin from ear
Damage leads to facial paralysis: Bell’s palsy, partial ageusia(loss of taste)
Term
glossopharyngel IX
Definition

mixed nerve 

§Motor –muscles for swallowing and the parotid salivary gland
§Sensory –taste (posterior one-third of the tongue and pharynx
prob: dysphagia (trouble sawllowing), partial ageusia (taste loss)
Term
hypoglossal XII
Definition

motor= tongue muscles

prob: atrophy of the tongue, dysarthria

Term
oculomotor III
Definition

raise eyelid, direct eyeball, constrict iris, control lens shape

motor=4 extraocular muscle (superior rectus, medial rectus, inferior rectus, and inferior oblique)

 

prob: strabismus (eyes not faced forward), ptosis (eyes drop down)

Term
olfactory I
Definition

sense of smell (bipolar)

 

sensory= smell from the olfactory epithelium

 

prob cause: anosmia (cant smell)

 

Term
optic II
Definition

 

impulses for vision

 

sensory= vision from retina of eye

 

prob: anopsia (no sight)

Term
optic nerve
Definition

sensory= vision from the retina of the eye

problems: anopsia(cant see)

Term
trigeminal V
Definition

sensory for various areas of the face, motor fibers for mastication

both

sensory= face, mouth, teeth, jaws

motor= chewing muscles and tensor tympani

prob: atrophy of mastication muscles and facial anesthesia

Term
trochlear iv
Definition
directs eyeball
motor= 1 extraocular muscle (superior oblique)
prob: eye rotated outward (exotropia)
Term
vagus X
Definition

 

§Motor - larynx and pharynx and viceral organs
§Sensory –viceral organs, taste from epiglottis
makes heart slow down (part of the sympathetic nervous system)
prob: dysphagia, tachy cardia, gastroparesis, incontinence
Term
vestibulocochlear VIII
Definition

sensory= balance from vestibule and hearing from the cochlea

prob: dysequilibrum and deafness

Term

ACE inhibitor

 

Definition

prevents angiotension

1 from creating angiotension

2 which would make your blood vessels constrict which raises your blood pressure (therefore blockeing it u lower blood pressure)

Term
beta blocker
Definition
Epinephrine binds to beta receptors which in the heart makes in beat more vigorous, wwhich makes blood pressure rise (blocking will lower blood pressure
Term
calcium
Definition
prevents calcum from depolarizing heart as strong therefore doesnt contract as strong , so there isnt as much pressure (lowering blood pressure
Term
diuretic
Definition
 makes you loose water therefore lowering blood volume and lowering blood pressure
