Nervous System Chapter 8

Front 1

what types of neurons are located entiry within the CNS?

Back 1

association neuron

Front 2

Defective oligodendrocytes interfere with the production of what substance?

Back 2

myelin

Front 3

what function is impaired if there is damage to afferent neurons?

Back 3

sensory functions because afferent neurons are sensory neurons that conduct impulses to the CNS

Front 4

what are some effects that produce some anesthetics?

Back 4

inhibiting the diffusion of Na through the cell membrane + thus blocking the initiation + conduction of nerve impulses

Front 5

what is the response to a threshold stimulus on a neuron?

Back 5

action potential

Front 6

what is a distinguishing feature of a neuron on which saltatory conduction occurs?

Back 6

nodes of Ranvier which are the gaps between myelin segments.

Front 7

many muscle fibers must contract at the same time. what type of neuronal circuit permits this?

Back 7

divergence circuit

Front 8

what is meningitis?

Back 8

an acute inflammation of the pia mater + the arachnoid. caused by bacteria.

Front 9

parkinson disease

Back 9

a condition in which the basal ganglia do not produce enough of the inhibitory transmitter dopamine. no dopamine there is an excess of excitatory signals that affect certain voluntary muscles producing rigidity

Front 10

what is the limbic system>?

Back 10

scattered but interconnected regions of gray matter in the cerebral hemispheres + diencephalon. it's involved in memory +emotions

Front 11

what is a reticular formation

Back 11

scattered but interconnected neurons + fiber pathways in the midbrain + brain stem. it is a functional system, maintains alertness

Front 12

in which cerebral lobe is the primary somatosensory area located?

Back 12

parietal lobe

Front 13

what comprises the white matter of the brain + spinal cord?

Back 13

myelinated fibers

Front 14

in which ventricle will CSF accumulate if there is a constriction or blockage i nthe cerebral aqueduct?

Back 14

3d ventricle

Front 15

what type of impulses are transmitted by the spinothalamic tracts of the spinal cord?

Back 15

sensory impulses of touch, pain, pressure + temperature

Front 16

what are the relationship between spinal nerve, its source from spinal cord + the region it innervates?

Back 16

the close relationship is that the skin surface area supplied by a single spinal nerve is called dermatome

Front 17

ADD

Back 17

attention deficit disorder

Front 18

ADHD

Back 18

attention defficit hyperactivity disorder

Front 19

ALS

Back 19

amyotrophic lateral sclerosis

Front 20

ANS

Back 20

autonomic nervous system

Front 21

CNS

Back 21

central nerovus system

Front 22

CSF

Back 22

cerebrospinal fluid

Front 23

CSM

Back 23

cerebrospinal miningitis

Front 24

CT

Back 24

computed tomography

Front 25

Back 25

cerebrovascular accident

Front 26

EEG

Back 26

electroencephalogram

Front 27

ICP

Back 27

intracranial pressure
