Q

neuron synapses onto blank of the muscle

A

end plate

1
Q

a muscle only has blank innervation

A

single nerve

2
Q

ach receptors are blank

A

nicotinic

3
Q

basal lamina is composed of blank and blank proteins

A

collagen, matrix

4
Q

basal lamina contains blank

A

acetylcholinesterase

5
Q

acetylcholinesterase blank acetylcholine

A

breaks down

6
Q

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

A

astrocytes

7
Q

ach is a blank gated channel

A

ligand

8
Q

end plate potential is blank than action potential

A

smaller

9
Q

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

A

end plate, action potential

10
Q

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

A

spatial summation (multiple signals)

11
Q

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

A

curare, ach, end plate

12
Q

when membrane becomes positive, blank has a higher flux

A

potassium

13
Q

when membrane is negative, blank flux is dominant

A

sodium
