Question

What is the role of Schwann cells in neurotransmission? *
1)Thermal insulation of neuronal axons
2)Limit the speed of the action potential
3)Enhance the speed of the action potential
4)Protect the neuro
nal soma from trauma​

Answer 1

Answer:

3 option is correct answer

Explanation:

as they release neuroactive substances that regulate the strength of synaptic transmission.

I hope you are satisfied with my answer

Answer 2

The role of Schwann cells in neurotransmission is to maintain the physical integrity of the synaptic junction.

Explanation:

The physical integrity of the synaptic junction is maintained by terminal Schwann cells, but they also carry receptors for neurotransmitters, allowing them to respond to neurotransmission.  As a result, they release neuroactive chemicals that modulate synaptic transmission strength.

Thermal insulation of neuronal axons:

• Increase the action potential's speed. Limit the speed of the action potential to avoid harm to the neuronal axons.

Limit the speed of the action potential:

• Following the conclusion of the absolute refractory period of the preceding action potential, successive action potentials occur with very powerful stimuli.

Enhance the speed of the action potential:

• Glial cells surround axons with a membraneous sheath termed myelin, similar to the insulation around wires in electrical systems, shielding the axon.

Protect the neuro nal soma from trauma​:

• The action potential cannot go backwards during the refractory period.
