Question 16

Neuroglial cells

Answer 16

found in both PNS & CNS
Helper cells
Help our neurons

Question 17

What are the jobs of astrocytes?

Answer 17

Maintains the blood- brain barrier

Forms & hold synapses

Question 18

What near blood vessels?

Answer 18

Astrocytes

Question 19

What else do astrocytes do?

Answer 19

Astrocytes completely cover the blood vessel, forming a to leave that blood siren & into the brain.
Sucks out certain nutrients from the blood & sending them to the neurons.

Question 20

Microloglial cells

Answer 20

Phagocytes

Question 21

What does microloglial do?

Answer 21

Moves around CNS & EAT UP THINGS THAT DON’T BELONG IN THE CNS.
Keeps CNS as clean as possible.

Question 22

Epedymal cells

Answer 22

Found in the ventricle of the brain & spinal cord.

Moves cerebral spinal fluid.

Question 23

What does cerebral spinal fluid do?

Answer 23

Provides nutrients to CNS

Question 24

Oligodrocytes

Answer 24

Produces myelin, they make enough myelin to cover 60 neurons
They crawl up and down the neurons to see where myelin needs to be repaired.

Question 25

Satellite cell

Answer 25

People don’t know what it does

Question 26

Shwann cell

Answer 26

produces little myelin

wraps around the neuron like a cake roll.

Question 27

When the adequate stimulus is added to an axon…

Answer 27

The amplitude of the action potential does not vary with the strength of the stimulus.
