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).

What are axons surrounded by?
Axons are surrounded by myelin sheath, a fatty material that insulates and protects the axon. Additionally, axons are also surrounded by Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, which help form the myelin sheath.
Do Schwann cells compose the cell body?
Myelin Sheath Cytoplasm Dendrites Cell Body
The Schwann cell forms a myelin sheath around the?
axons of neurons in the peripheral nervous system. The myelin sheath helps to insulate the axon and improve the speed of electrical signal conduction along the neuron. Schwann cells are also involved in nerve regeneration and support neuron function within the peripheral nervous system.

The schwann cell forms a Myelin Sheath around what part of the nerve?
The Schwann cell forms a myelin sheath around the axon of the nerve.
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.
What does the schwann cell form a myelin sheath around?
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.
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 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 role of Schwann cells in forming the myelin sheath?
Schwann cells are responsible for wrapping around nerve fibers in the peripheral nervous system to form the myelin sheath. This insulating layer helps in the rapid conduction of nerve impulses along the nerve fiber. Schwann cells also provide support and maintain the health of the nerve fiber.
What is the sheath of a schwann cell that contains cytoplasm and a nucleus and encloses myelin?
Neurilemma
