Chapter 9

Question 1

Somatic

Answer 1

voluntary

Question 2

autonomic

Answer 2

Involuntary

Question 3

Nerve impulses

Answer 3

How the nervous system communicates with the rest of the body

Question 4

Afferent impulses

Answer 4

Sensory

Carriers impulses into CNS

Question 5

Efferent impulses

Answer 5

motor

Carry away from CNS by spinal chord and cranial nerves

Question 6

General sensation

Answer 6

temp, touch, pressure, pain

Question 7

Special senses

Answer 7

Vision, audition, olfaction (smell), Gustation (taste), equilibrium

Question 8

CNS functions

Answer 8

Receive sensory impulses from PNS
Process and store info
send motor impulses

Question 9

PNS functions

Answer 9

transducing energy into sensory impulses
conducting sensory impulses to the CNS
Distributing motor impulses to muscles and glands

Question 10

neurons

Answer 10

functional cells of the nervous system that conduct nervous impulses

Question 11

multipolar

Answer 11

Morphological type of neuron:
several dendrites one axon
all efferent and interneurons are multipolar (morphological types of neurons)

Question 12

bipolar

Answer 12

Morphological type of neuron:
single long dendrite and single axon
least common type. Only in EYE, EAR, and NOSE

Question 13

pseudounipolar

Answer 13

Morphological type of neuron:
cell body is offset
single long dendrite and single axon

Question 14

Ganglia

Answer 14

groups of cell bodies in the in the PNS, called a NUCLEI in the CNS

Question 15

Sensory ganglia

Answer 15

associated with cranial and spinal nerves
attachment to brain and spinal cord
convey general sensory input into CNS
SA and VA neurons

Question 16

Autonomic ganglia

Answer 16

only VE neurons 3 types: Terminal, sympathetic trunk, named peripheral

Question 17

Neuroglia

Answer 17

support neurons, don’t transmit impulses

Question 18

astrocytes

Answer 18

neuroglia

blood brain barrier. Largest and most common CNS

Question 19

ependymal cells

Answer 19

neuroglia

cuboidal, line ventricles and spinal cord central canal, make CSF

Question 20

Microglia

Answer 20

neuroglia

phagocytic cells in CNS

Question 21

Oligodendrocyte

Answer 21

neuroglia

form myelin sheaths in CNS

Question 22

Neurolemmocyte

Answer 22

-neuroglia
form myelin sheaths in PNS
speed up transmissions

Question 23

Satellite cell

Answer 23

-neuroglia

support the ganglia in PNS

Question 24

resting potential

Answer 24

-65mV

Question 25

somatic efferent neurons

Answer 25

supply motor impulses to skeletal muscle

Question 26

somatic afferent neurons

Answer 26

vision, hearing, skin, muscles, bones, joints

Question 27

visceral afferent neurons

Answer 27

DOG
Deep organs
olfaction (smell)
gustation (taste)

Question 28

Visceral efferent neurons

Answer 28

smooth m.t.
cardiac m.t.
glandular epi

Question 29

Frontal lobe

Answer 29

anterior most lobe, voluntary control over skeletal muscles; verbal communication and thought

Question 30

parietal lobe

Answer 30

general senses/sensory preception

Question 31

temporal lobes

Answer 31

hearing and equilibrium

Question 32

occipital lobe

Answer 32

vision and coordination of eye movement

Question 33

insular lobe

Answer 33

involved in memory
