Question 1

Absolute in a refractory Period.

Answer 1

Generating action potential, not possible 

Question 2

Relative refractory Period.

Answer 2

Cell undergoing hyper polarization, trying to fire, another action potential

Question 3

What does propagate action potential do

Answer 3

Allowing action potential to travel along the axon

Question 4

The speed of action potential

Answer 4

Myelinated axon is faster

Question 5

Type A

Answer 5

Larger in diameter, myelinated

Question 6

Type B

Answer 6

Medium diameter, lightly myelinated

Question 7

Type C

Answer 7

Smaller diameter, unmyelinated

Question 8

Synapse can be

Answer 8

-Nerve to nerve
-Nerve to Oregon
-Nerve to gland

Question 9

Electrical synapse

Answer 9

Change and membrane
Example: ligand gated channel

Question 10

Chemical synapse

Answer 10

Neuro transmitters
Example : acetylcholine

Question 11

What are the two cells in a synapse?

Answer 11

Presynaptic and postsynaptic membrane

Question 12

What is a good example of electrical synapse

Answer 12

Cardiac muscle cell

Question 13

What’s a good example for chemical synapse?

Answer 13

Neuromuscular junction

Question 14

What is intercalated discs?

Answer 14

Dark disc on muscle cell in heart

Question 15

Neuro transmitter removal

Answer 15

ACH runs into an enzyme called said ACHesterase that will Cleve them with Choline and acetic acid

Question 16

What will inhibiting the enzyme do to the muscle cell

Answer 16

It will increase asetycholine and contracting muscle

Question 17

Neuro transmitter of norepinephrine

Answer 17

Enzymes break down the norepinephrine is monoamine oxidase

Question 18

What will decreasing the monoamine oxidase due to norepinephrine?

Answer 18

It will increase

Question 19

Spatial summation

Answer 19

Is one action potential per synapse

Question 20

Temporal summation

Answer 20

Two action potential per synapse

Question 21

Combine spatial and temporal summation

Answer 21

-AP inhibits and excites sell with other AP
-Has multiple in single AP per synapse

Question 22

If there is more excitatory synapse than inhibits synapse, it’s

Answer 22

Action potential is fired

Question 23

If there’s more inhibiting synopsis, then excitatory synapse is it’s

Answer 23

There’s no AP

Question 24

Convergent pathway

Answer 24

Many converge and synapse with smaller number of neurons

Question 25

Divergent pathways

Answer 25

Small number of presynaptic neurons with postsynaptic neurons

Question 26

Oscillating circuit

Answer 26

Output, cause, reciprocal activation
