NR 304 Exam 2 || Verified for Accuracy.
central nervous system (CNS) correct answers brain, spinal cord
peripheral nervous system (PNS) correct answers everything but brain and spinal cord, 12 cranial
nerves
cerebral cortex correct answers 2 hemispheres, 4 lobes per hemisphere
can get approximation or where a stroke happened
frontal lobe correct answers personality, behavior, emotions, intellectual function
parietal lobe correct answers primary center for sensation
occipital lobe correct answers primary visual receptor center (back of head)
temporal lobe correct answers auditory reception center, taste, smell
Wernicke's area correct answers language comprehension
temporal lobe
receptive aphasia (hear sound, but it has no meaning)
Broca's area correct answers mediates motor speech
frontal lobe
expressive aphasia (comprehends, but only garbled sounds comes out when try to speak)
,hypothalamus correct answers appetite, sex drive, temperature, heart rate, BP, sleep,
anterior/posterior pituitary gland regulation, coordination of autonomic nervous system (ANS),
stress response, emotional status
cerebellum correct answers under occipital lobe
coordination of voluntary movements, equilibrium, muscle tone (does not initiate movements)
brainstem correct answers automatic survival functions
cranial nerve (CN) III-XII originate here
pons (ascending sensory and descending motor tracts)
medulla (continuation of spinal cord in brain; contains all fiber tracts connecting brain and spinal
cord)
spinal cord correct answers mediates reflexes
butterfly shape with posterior/anterior horns
(ugh, the slide in the photo is beautiful<3)
upper motor neurons correct answers located completely within CNS
diseases (cerebrovascular accident, cerebral palsy, multiple sclerosis, etc.)
lower motor neurons correct answers final contact with muscles
in anterior gray column of spinal cord
movement must be translated into action by these:
-cranial nerves and spinal nerves of PNS
diseases (spinal cord lesions, poliomyelitis, amytrophic lateral sclerosis)
reflexes correct answers basic defense mechanisms of NS
involuntary
, What are the 4 types of reflexes? correct answers 1. deep tendon "myotatic" (ex: knee jerk)
2. visceral (ex: pupillary response to light)
3. superficial (ex: corneal, abdominal)
4. pathologic (ex: Babinski's, extensor plantar)
cranial nerves correct answers enter/exit the brain
CN1 & CN2 extend from cerebrum,CN3-CN11 extend from lower diencephalon and brainstem
12 pairs CN's supply head/neck except vagus (travels to heart, respiratory muscles, stomach,
gallbladder)
spinal nerves correct answers 31 pairs named for where exit:
8 cervical (C1-C8)
12 thoracic (T1-T12)
5 lumbar (L1-5)
5 sacral (S1-S5)
1 coccygeal (C0)
autonomic nervous system (ANS) correct answers mediates unconscious activity
carry fibers divided into two parts:
-somatic fibers innervate skeletal (voluntary) muscles
-autonomic fibers innervate smooth (involuntary) muscles, cardiac muscle, and glands
infants and neurologic system correct answers neurologic system not completely developed at
birth
