graded A+ Guaranteed Success!!
central nervous system (CNS) - (ANSWER)brain, spinal cord
peripheral nervous system (PNS) - (ANSWER)everything but brain and spinal cord, 12 cranial nerves
cerebral cortex - (ANSWER)2 hemispheres, 4 lobes per hemisphere
can get approximation or where a stroke happened
frontal lobe - (ANSWER)personality, behavior, emotions, intellectual function
parietal lobe - (ANSWER)primary center for sensation
occipital lobe - (ANSWER)primary visual receptor center (back of head)
temporal lobe - (ANSWER)auditory reception center, taste, smell
Wernicke's area - (ANSWER)language comprehension
temporal lobe
receptive aphasia (hear sound, but it has no meaning)
Broca's area - (ANSWER)mediates motor speech
frontal lobe
expressive aphasia (comprehends, but only garbled sounds comes out when try to speak)
hypothalamus - (ANSWER)appetite, sex drive, temperature, heart rate, BP, sleep, anterior/posterior
pituitary gland regulation, coordination of autonomic nervous system (ANS), stress response, emotional
status
cerebellum - (ANSWER)under occipital lobe

graded A+ Guaranteed Success!!
coordination of voluntary movements, equilibrium, muscle tone (does not initiate movements)
brainstem - (ANSWER)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 - (ANSWER)mediates reflexes
butterfly shape with posterior/anterior horns
(ugh, the slide in the photo is beautiful<3)
upper motor neurons - (ANSWER)located completely within CNS
diseases (cerebrovascular accident, cerebral palsy, multiple sclerosis, etc.)
lower motor neurons - (ANSWER)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 - (ANSWER)basic defense mechanisms of NS
involuntary
What are the 4 types of reflexes? - (ANSWER)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 - (ANSWER)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 - (ANSWER)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) - (ANSWER)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 - (ANSWER)neurologic system not completely developed at birth
sensory and motor development proceed with gradual acquisition of myelin needed to conduct most
impulses
aging adult and neurologic system - (ANSWER)decreased muscle strength, impaired fine
coordination/agility, loss of vibratory sense at ankle, decreased/absent Achilles reflex, pupillary miosis,
irregular pupil shape, decreased pupillary reflexes, decreased velocity of nerve conduction (slow
reaction time), increased delay at synapse (decreased sensation touch, pain, taste, smell), motor system
