what is the myelin sheath?
|
|
formed from a special cells which wrap themselves around the neuron & protects the axon and speeds up the electrical transmission of the impulse
|
|
|
slows down the electrical transmission of the impulse & is formed by a group of cells which sprial out from the neuron
|
|
|
Either A or B

|
None of the above

Explanation:
Detailed explanation-1: -A myelin sheath is a sleeve (sheath) that’s wrapped around each nerve cell (neurons). It’s a protective layer of fat (lipids) and protein that coats the main “body” section of a neuron called the axon.
Detailed explanation-2: -In the central nervous system, myelin is formed by multipolar glia, oligodendrocytes, that can extend dozens of slender cell processes to ensheath multiple axons simultaneously.
Detailed explanation-3: -Glial cells are the key element for supporting the messages neurons send and receive all over the body. Much like the insulation around the wires in electrical systems, glial cells form a membraneous sheath surrounding axons called myelin, thereby insulating the axon.
