What is the sheath of the Schwann Cell also called?
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 up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).

Why does the myelin sheath have gaps in it?
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
What are schwanna cells?
First off it's SCHWANN CELLS. They are also called neurolemnocytes. They are the cells that support the peripheral nervous system. Scwann cells are any cells that are wrapped around nerve axons. A single schwann cell is a single segment of an axon's myelin sheath.

What is another name for the sheath of schwann?
another name for the sheath of schwann is neurilemma.
Formation of Myelin Sheath and also Neuron introduction?
The formation of myelin sheath around the axon is called the myelinogenesis. In the peripheral nerve, the myelinogenesis starts at 4th month of intrauterine life. It is completed only in the second year after birth. Before myelinogeneis, Schwann cells of the neurilemma are very close to axolemma as in the case of unmyelinated nerve fiber. The membrane of the schwann cell is double layered. The schwann cells wrap up and rotate around the axis cylinder in many concentric layers. The concentric layers fuse to produce the myelin sheath but the cytoplasm of the cells is not deposited. Outermost membrane of Schwann cell remains as neurilemma. Nucleus of these cells remains in between myelin sheath and neurilemma. In the central nervous system, the schwann cells are absent and the myelin sheath is formed by the neuroglial cells called the oligodendroglia.

What creates the myelin sheath in the PNS?
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.
Formed by schwann cells in the PNS?
Myelin sheath
Why does the myelin sheath have gaps in it?
Because the sheath is produced by several Schwann cells that arrange themselves end to end along the nerve fiber, each Schwann cell forms only one part of the tiny segment of the sheath.
What is neuroglial cells that form the fatty myelin sheath on the neurons of the brain and spinal cord called?
Schwann cells (PNS)

What is the sheath of a schwann cell that contains cytoplasm and a nucleus and encloses myelin?
