What is the difference between myelin and neurilemma

It is a nucleated cytoplasmic layer of schwann cells that surrounds the myelin sheath of axons. This tutorial digs into the past to investigate the origins of life. The section is split into geological periods in the.. Plantlife can be studied at a variety of levels, from the molecular, genetic and biochemical level through organelles, c.. Different pregnancy and birth control and contraception strategies are described.

It is formed by the wrapping of Schwann cells throughout the axon of the neuron. In the peripheral nervous system, they assist in producing the nerve fibers whereas throughout the central nervous system they produce a white colored matter which every end up defending the axon and insulate it. They are relying on the Neurilemma for canopy, nonetheless the latter one is not relying on it in any method and attributable to this reality could possibly be considered a lot much less superior as in contrast though it does perform additional options.

The portions of the nerve fiber which is surrounded by the myelin sheath are called the internodes.

Each internode is myelinated by a single Schwann cell. The oblique clefts in the myelin sheath help to conduct nutrients to the deepest Schwann cells. Figure 2: Myelinated Nerve Fibers. The major function of the myelin sheath is to electrically insulate the nerve axon. The capacitance of the axon fiber is reduced at the internodes. Therefore, the conduction of the nerve impulses occurs only through the nodes of Ranvier.

The cross sections of myelinated nerve fibers are shown in figure 2. Neurilemma: Neurilemma is the plasma membrane of Schwann cells that surrounds the myelinated nerve fibers. Myelin Sheath: Myelin sheath is the insulating covering of the nerve fibers that increase the speed of conduction of nerve impulses.

Neurilemma: Neurilemma is the outer most layer of a myelinated nerve fiber. Myelin Sheath: Myelin sheath is covered by neurilemma. Apart from the nerve cells neurons , the nervous system is supported by two types of cells; Schwann cells and Oligodendrocytes, which are commonly known as neuroglia.

Neurilemma and myelin sheath are two important cellular components derived from neuroglia. The key difference between Neurilemma and the myelin sheath is that Neurilemma is the cytoplasm and the nuclei of the Schwann cells lying outside the myelin sheath while M yelin sheath is a modified cellular membrane wrapped around the axon of the neurons. In this article, the difference between neurilemma and myelin sheath is described further.

The cytoplasm and the nuclei of the Schwann cells which lie outside the myelin sheath are collectively called the neurilemma. The neurilemma is only present in the peripheral nervous system and is absent in the central nervous system due to the lack of Schwann cells.
