NUR 172- Exam 3 (Neuro)
Which division of the nervous system includes the brain and spinal cord? - answer
Central nervous system (CNS)
Which division of the nervous system includes the motor and sensory nerves which
carry messages between CNS and remote parts of the body? - answer Peripheral
nervous system (PNS)
The PNS consists of - answer-cranial nerves
-spinal nerves
-ANS
The reticular activating system (RAS) is responsible for - answer Wakeful state-
interruption of blood supply to RAS causes altered LOC
What are the two divisions of the ANS? - answer sympathetic and parasympathetic
What is the action of the sympathetic nervous system? - answer Fight or flight
response. Increased heart rate, bronchodilation, decreased gastric motility and
secretion, decrease intestine peristalsis, increased release of glucose from the liver,
dilation of pupils, increased sweating (cholinergic), increased secretion of adrenal
medulla, relaxes bladder
What are the main neurotransmitters involved in sympathetic nervous system? -
answernorepinephrine and epinephrine
What is the main neurotransmitter of the parasympathetic nervous system? -
answeracetylcholine
What is the action of the parasympathetic nervous system? - answerRest and digest:
decrease heart rate, constrict the bronchioles and stimulate secretion, increase
salivation, increase GI peristalsis, and pancreatic secretion, constricts the pupils,
causes bladder contraction and dilates vessels of the genitalia
Which division of the nervous system regulates involuntary functions of the internal
organs? - answerAutonomic nervous system (ANS)
Example of metabolic disorder causing RAS dysfunction - answerhypoglycemia
____ is when the patient is difficult to arouse and needs constant stimulation in order to
follow a simple command. She may respond verbally with one or two words, but will drift
back to sleep between stimulation.
