The neurilemma is composed of the Schwann cells, which are a type of neuroglial cell that help to provide support and insulation to axons in the peripheral nervous system. Schwann cells play a crucial role in nerve function by producing myelin, which helps to increase the speed of electrical signal conduction along the axon.
What else can I help you with?
Do all nerve cells have a neurilemma?
No, not all nerve cells have a neurilemma. The neurilemma is a part of peripheral nerve fibers but is not present in the central nervous system. It is a layer of Schwann cells that surround and protect the axon of peripheral nerves.
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).
Neurilemma is wrapped around most exons in the nervous system excpect for the?
Neurilemma, or Schwann cell membrane, wraps around most axons in the peripheral nervous system, providing insulation and support. This covering is absent in the central nervous system, where axons are myelinated by oligodendrocytes instead.
The sheath of Schwann is also called what?
The sheath of Schwann is also called the myelin sheath. It is a layer of fatty material that surrounds and insulates nerve fibers, allowing for faster transmission of nerve impulses.
What are molecular composed of?
A compound is composed from atoms of chemical elements.
Is mylean sheath the same as neurilemma-?
Yes, the mylean sheath is the same as the neurilemma.
Do all nerve cells have a neurilemma?
No, not all nerve cells have a neurilemma. The neurilemma is a part of peripheral nerve fibers but is not present in the central nervous system. It is a layer of Schwann cells that surround and protect the axon of peripheral nerves.

The neurilemma is covered by WHAT loose connective tissue called the?
endoneurium
What forms a protective tunnel around the nerve fibers?
neurilemma
The sheath around some neuron fibers that aids in regeneration?
neurilemma
The neurilemma of axons in the peripheral nervous system is formed by?
schwann cells
What is neurilemma?
Neurilemma, also known as the Schwann sheath, is a layer of cells that encases the axons of peripheral nerves. It is formed by Schwann cells, which provide insulation and support to the nerve fibers, aiding in the regeneration of damaged axons. The neurilemma plays a crucial role in the peripheral nervous system by facilitating the repair process after injury and maintaining the health of nerve fibers.
