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.


What is the sheath of Schwann called?

Its the Neurilemma.


What is neurilemma composed of?

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.


Function of neurilemma in nerve cell regeneration?

Neurolemma is just an outer shell of the myelin sheath, it's function is to protect a myelinated cell from injury and aid in its healing from injury by allowing information to travel faster to the brain that an unmyelinated cell.

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).
