Ch 4 - Cells of Nervous System

Question 0

modifies secretory proteins

Answer 0

golgi body

Question 1

these vesicles result from invagination of the cell membrane

Answer 1

endosomes

Question 2

protein signal that helps with endocytosis

Answer 2

clathrin

Question 3

largest cytoskeleton part made of protofilaments… dimerized (BLANK)

Answer 3

microtubules, coiled

Question 4

negative end of microtubules are oriented in the blank of the cell

Answer 4

center

Question 5

making a microtubule longer process

Answer 5

polymerization

Question 6

three main parts of a cytoskeleton

Answer 6

neurofilaments, microfilaments, microtubules

Question 7

bones of neuron that are smaller but don’t really ever change

Answer 7

neurofilaments

Question 8

thinnest part of skeleton only made of two strands of actin

Answer 8

microfilaments

Question 9

microfilaments shape can change and move and are usually on the blank of the cell

Answer 9

outside

Question 10

neurons need blank transport in order to reach the far ends of the cells

Answer 10

active

Question 11

retrograde means transporting blank the cell body

Answer 11

toward

Question 12

anterograde means transport blank the cell body

Answer 12

away from

Question 13

cytoskeleton proteins only need to be transported in the blank direction

Answer 13

anterograde

Question 14

start and stop transport that occurs because of collisions with others on the road system that have to get back on

Answer 14

saltatory conduction

Question 15

how kyosin transports anterograde

Answer 15

legs attach then alternate detach to road

Question 16

map 1 protein transports blank and is slower than blank

Answer 16

retrograde, anterograde

Question 17

golgi stain simply stains the neuron blank… not the blank

Answer 17

dark, golgi body

Question 18

most golgi bodies are in the blank but can also be spread out all over

Answer 18

soma

Question 19

make up myelin sheath in CNS

Answer 19

oligodendrocytes

Question 20

make up myelin sheath in PNS

Answer 20

schwann cells

Question 21

each blank of myelin is a single schwann cell

Answer 21

segment

Question 22

shiver is tremors due to incomplete blank

Answer 22

myelination

Question 23

these help with saltatory conduciton

Answer 23

nodes of ranvier

Question 24

this is not myelinated

Answer 24

axon hillock

Question 25

star shaped glia in all parts of brain

Answer 25

astrocytes

Question 26

astrocytes form the blank

Answer 26

blood brain barrier

Question 27

astrocytes are the blank between blood and neurons of the brain and stabilize the blank by regulating blank

Answer 27

intermediary, synapse, concentrations

Question 28

glia from bone marrow that is in the brain

Answer 28

microglia

Question 29

microglia regulate cleaning up blank in the brain

Answer 29
