Cranial Nerves
The cranial nerve that regulates hearing and balance
vestibulocochlear
This cranial nerve is responsible for movement of the eye from side to side.
abducens
These are the two subdivision of the PNS
Somatic and Autonomic
vestibulocochlear
VIII
This is caused by a rupture of lumbar disc or arthritic changes resulting in leg pain.
Sciatica
The cranial nerve that regulates vision
Optic Nerve
A very painful neuritis that is unilateral on the body and affects dermatomes.
Shingles
This is the number of cranial nerve pairs in the PNS
12
optic
II
Injury to this nerve can cause drooping shoulder, muscle atrophy, limited elevation of shoulder, and winged scapula
Accessory Nerve
Nerve in control of the pharynx/larynx, digestive system, heart and the longest nerve
Vagus
This is the primary neurotransmitter for the Sympathetic Nervous System
Epinephrine/ Norepinephrine
Parasympathetic stimulation of this nerve stimulates tears.
Facial
glossopharyngeal
IX
Testing this nerve can be done by asking the patient to stick their tongue out - if it deviates to one side, there is damage to this nerve
hypoglossal
Thus cranial nerve is responsible for taste on the anterior portion of the tongue
Facial
Involves the 5th nerve, cause is unknown, extremely painful condition
Trigeminal Neuralgia
This is the number of spinal nerve pairs in the PNS
31
olfactory
This causes lack of feeling in the feet, which can cause difficulty walking.
Provides sensory for the mandible and maxilla of the face.
Trigeminal
This is the primary neurotransmitter for the Parasympathetic Nervous System
Acetylcholine
The Autonomic Nervous System is responsible for these functions in the body
Rest and Digest: Digestion, lower the HR/ RR
Fight or flight: Increase HR, RR, BP, release glucose stores
Vagus
X
A patient presents with facial droop symptoms. This is how you can tell if this is or isn't a stroke.
Bells Palsy: Physical Presentation only in the face- facial drooping, drooling, trouble talking or swallowing
Stroke: Neuro and Physical (whole body)- weakness in the arms and legs, trouble finding words, altered mental status
