Define the myelin sheath?

What is the purpose of the myelin sheath? RIGHT Answer--- The myelin sheath serves as an insulator for the axon. ...

Myelin Sheath Myelin Sheath

The endoneurium surrounds and protects the myelin sheath.

Myelin sheath is a covering of neurons and it does not travel.

Multiple sclerosis affects the myelin sheath.

A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron. ...

Oligodendrocytes produce the myelin sheath for neurons in the CNS. Schwann cells form the myelin sheath in the PNS. ...

Oligodendrocytes are specialized neurolgical cells that produce myelin sheath. ...

the Myelin Sheath Myelin Sheath Your welcome I had to look for it

The schwann cell is the myelin sheath.

The myelin sheath insulates nerve axons so that nerve impulses do not leak out. ...

The myelin sheath wraps around the around the axon of a neuron. The gaps of the myelin sheath are not insulated and are therefore capable of generating electrical activity. ...

Neurilemma sheath/myelin sheath

Myelin sheath insulates axons for speedier signaling

The axon branch off a neurons are covered by myelin sheath to give insulation to the same. Myelin sheath is made up of cells, which come from mesoderm. ...

Schwann cells make the myelin sheath in the PNS. Each of the Schwann cells myelinate their own segment of the axon, they work together to make the myelin sheath. ...

Grand mal epilepsy is caused by destruction of the myelin sheath. There are few other diseases, that are associated with myalin sheath destruction. ...

if neurons didn't have myelin sheath then the transmission of nerve impulses is slowed or stopped ...

In the fatty myelin sheath there are gaps between the axons. The myelin sheath gaps are referred to as the nodes of Ranvier. ...

You can have benign tumors of myelin sheath cells, like astrocytoma. Nerve cells do not divide and so you do not get tumors of nerve cells. Also destruction of the myelin sheath is the cause of MS (multiple sclerosis). ...

Muscular sclerosis is hardening and degeneration of the myelin sheath. Muscular sclerosis Multiple sclerosis is a disorder marked by destruction of the myelin sheath on neurons in the CNS and replacement with hard scar tissue. ...

There are few diseases that destroy the myelin sheath like sub acute combined degeneration of myelin sheath. There is also ascending myelitis, which is a serious complication of rabies vaccine. The incidence is one in ten to thirty thousand. ...

The sheath that covers an axon is called myelin sheath or medullated sheath which is externally covered by neurilemma. ...

The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system. ...

Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs...
