Question

The fatty insulating sheath (known as white matter) which coats the axon of the central and peripheral neurons is called?

1) Myelin sheath
2) Dendrite
3) Synapse
4) Neurotransmitter

Answer 1

The fatty insulating sheath that coats the axon of neurons is called the myelin sheath. It allows for faster transmission of electrical signals.

Step-by-step explanation:

The fatty insulating sheath that coats the axon of central and peripheral neurons is called the myelin sheath. It is a lipid-rich layer of insulation that surrounds the axon and is produced by glial cells called Schwann cells. The myelin sheath allows for faster transmission of electrical signals along the axon.
