nervous system

Question 1

parts of the neuron

Answer 1

cell body, dendrites and axon

Question 2

soma

Answer 2

cell body- houses the nucleus and the cytoplasm

Question 3

perikaryon

Answer 3

cytoplasm within the cell body

Question 4

chromatophilic substance

Answer 4

made of rough ER/nissl bodies

Question 5

dendrites

Answer 5

process on the neuron where graded potentials are initiated

Question 6

axon

Answer 6

process on the neuron that propagates action potentials away from the cell body

Question 7

axoplasm

Answer 7

cytoplasm within the axon

Question 8

axolemma

Answer 8

plasma membrane of an axon

Question 9

is there chromatophilic substance in the axon?

Answer 9

no. its only in the cell body

Question 10

axon hillock

Answer 10

where the axon attaches to the cell body

Question 11

myelin sheath

Answer 11

insulating cover around an axon that are made of glial cells

Question 12

what kinds of cells make up myelin sheath ?

Answer 12

neurolemmocytes/Schwann cells or oligodendrocytes

Question 13

where are schwann cells found?

Answer 13

peripheral nervous system

Question 14

where are oligodendrocytes found?

Answer 14

central nervous system

Question 15

nodes on ranvier

Answer 15

also known as a neurofibril node, gaps between neurolemmocytes

Question 16

telodendria

Answer 16

axon terminals

Question 17

synaptic knobs

Answer 17

tips of the telodendria

Question 18

synaptic vesicles

Answer 18

housed in synaptic knobs and contains neurotransmitters

Question 19

sensory neurons

Answer 19

afferent neurons, conduct input from somatic and visceral receptors to CNS

Question 20

motor neurons

Answer 20

efferent neurons, conduct output from CNS to somatic and viseral effectors
