Propogation

Question 1

What is the resting membrane potential

Answer 1

It is the amount of volatile that the neuron has at rest -70 mV

Question 2

Excitatory post synaptic potential

Answer 2

Cell voltage becomes more positive likely to pass the current down the axon

Question 3

Inhibitory post synaptic potential

Answer 3

Cell voltage become more negative and likely to pass the current down the axon.

Question 4

Inhibition

Answer 4

Is the process of passing a current down that is less cell voltage than at the testing membrane

Question 5

Depolarization

Answer 5

Is when the cell voltage goes up from resting potential

Question 6

What does the cell have to do when both positive and negative Nuevo transmitters reach the receptor

Answer 6

It has to decide what to do with the i for and decide what to do. It must send many action potentials

Question 7

Threshold

Answer 7

This is a value that will allow the cell to continue passing the action potential down the axon

Question 8

What is the threshold for Na+that will cause the voltage gate channels to open

Answer 8

-55mV

Question 9

There is resistance Of the current of ions flowing

Answer 9

True.

Question 10

How does the cell make the wave of an toon potential continue fmdown the neuron

Answer 10

The booster station make it so the cell voltage must reach the same amount so it’s continually passed down

Question 11

Nodes

Answer 11

Small breaks between myelinated axon. Nodes contain voltage gated sodium channels that allow sodium to come in a make action potential boosted

Question 12

Where is Myelin made

Answer 12

It is made of the phospholipid membranes of certain glial cells. Wrapped around the axon like rubber aroun an electrical wire

Question 13

Myelin allows for

Answer 13

Fewer boost and quicker speeds

Question 14

What type of axons do pain carrying neurons have.

Answer 14

Very wide allows for lest resistance I. The axon for the sodium current

Narrow Avon’s are the slowest

Question 15

So pain pathways have thin or thick myelinated pathways

Answer 15

Thick and myelinated as possible to make transmission fastes

Question 16

Unmiliinated nuerons exist where

Answer 16

In gastric track. We break down food at a constant rate so these neurons axons don’t have to be thick or mylyleniated

Question 17

Where do volatile fatter sodium channels occur

Answer 17

At the nodes and trigger zone

Question 18

Ligand is another word for

Answer 18

Neurotransmitter

Question 19

Direct neurotransmitter action

Answer 19

The same place that the Nt binds is the same place the ions flows through

These are very fast acting

For example skeletal muscle

Question 20

Indirect neurotransmitter channel

Answer 20

Not the same channel opens where the neurotransmitter binds. It takes time for the channel that’s away to open. Some neurotransmitters can activate enzymes or turn of nueclous coding genes

These are slow acting

For eaxamole the heart beats slowly to slow down heart rate to fill and squeeze blood out and smooth muscle in intestine

Question 21

There are over how many nt in the body

Answer 21

200

Question 22

What are the five groups of my

Answer 22

Acetylcholine. 
Biogenic
Amino acids 
Peptides 
Purines

Question 23

Acetylcholine

Answer 23

Can be both excititoray or inhintaroy

Binds to al three muscles. Skeletal smooth and cardiac

When in skeletal opens sodium so fast acting

When in heart muscle it open up channels indirectly for potassium to leave inhibitory

When I’m smooth muscle it opens up calcium indirectly so slow acting

Question 24

Agonist

Answer 24

Helps or enhance the action of the NT More excitement in the body or less excitement

Question 25

Antagonist

Answer 25

Stop NT from doing their job

Botox is example because it prevent acetylcholine from doing its jobs of contracting skeletal muscle.
