Ch 9 - Signaling at Nerve Muscle Synapse

Question 0

neuron synapses onto blank of the muscle

Answer 0

end plate

Question 1

a muscle only has blank innervation

Answer 1

single nerve

Question 2

ach receptors are blank

Answer 2

nicotinic

Question 3

basal lamina is composed of blank and blank proteins

Answer 3

collagen, matrix

Question 4

basal lamina contains blank

Answer 4

acetylcholinesterase

Question 5

acetylcholinesterase blank acetylcholine

Answer 5

breaks down

Question 6

since blank are not in the periphery, acetylcholinesterase is there to turn off signals

Answer 6

astrocytes

Question 7

ach is a blank gated channel

Answer 7

ligand

Question 8

end plate potential is blank than action potential

Answer 8

smaller

Question 9

ach receptors will create a blank potential, but when paired with sodium voltage gated receptors blank can be formed

Answer 9

end plate, action potential

Question 10

CNS relies on blank to create an action potential unlike for a muscle cell

Answer 10

spatial summation (multiple signals)

Question 11

this stops an action potential from happening by turning down blank receptors to decrease the blank potential

Answer 11

curare, ach, end plate

Question 12

when membrane becomes positive, blank has a higher flux

Answer 12

potassium

Question 13

when membrane is negative, blank flux is dominant

Answer 13

sodium
