Outermist layer of cells membrane of schwann cell that encloses nucleus and cytoplasm is
Answers
Outermost layer of cells membrane of Schwann cell that encloses nucleus and cytoplasm is neurilemma.
- Schwann cells are the cells which are responsible for the myelination of axons.
- Axons are the long, electric impulses carrying part of a neuron.
- After myelination, the myelin sheath forms the innermost layer of the wrapping.
- The outermost layer is referred to as the neurilemma which contains the nucleus and the cytoplasm.

Outermost layer of cells membrane of schwann cell that encloses nucleus and cytoplasm is Neurilemma.
Explanation:
1. In the peripheral system of nervous, Neurilemma forms the most outermost or the outer covering of the nerve fibre.
2. This outer most layer or the covering is also known as the Schwann's seath.
3. This is responsible for creating the structures present outside our spinal cord and the brain.
4. This layer of Schwann cells has nucleus and thus is nucleated.
5. Even after the nerves are crushed or cut, this outermost layer called Neurilemma do not ever gets degenerated.
6. It also has the role to cover the axons which forms a part of the non-myleinated fibres of nerve.
7. The central type of nervous system do not have Neurilemma. It is because the axons of that is surrounded by oligodendrocytes.
