When the peripheral nervous system develops, Schwann cells line up along unmyelinated axons at regular intervals that eventually become the nodes of Ranvier (important for saltatory nerve condution). The ensheathing process takes place as Schwann cells wrap around the axon many times over, creating concentric layers whose cytoplasm progressively condenses. Contact with the axons also activates myelin genes leading to the expression of myelin glycoproteins and lipids across the Schwann cell plasma membrane. The sheath therefore consists of plasma membrane, cytosol, lipids, glycoproteins, and the Schwann cell nucleus.
*So basically, the schwann cells is a protective membrane that covers the axon. It also produces myelin sheath (the coating of a neuron), which increases the speed of the nerve impulse.
Another name for Schwann cell is neurolemmocyte. Schwann cells are a type of glial cell that provides support and insulation to axons in the peripheral nervous system.
The Schwann cell forms a myelin sheath around the axon of the nerve.
No, Schwann cells are a type of glial cell found in the nervous system of animals, including humans. They play a role in supporting and protecting neurons. Plant cells, on the other hand, are the basic unit of plant structure and function.
The nucleus is the organelle that manages and controls all cell functions in a eukaryotic cell. It contains the cell's genetic material and regulates gene expression, cell division, and protein synthesis.
Schwann cells form a myelin sheath around peripheral nerve fibers in the peripheral nervous system.
It controls the activities within the cell, contains genetic material and it is essential for cell division.

Neurilemma
the thingy inside a nucleus that helps it funtion
to protect the cell
to keep the fluids of the cell from getting out
The function of a cell is determined by its primary structure.
The cell wall function is to protect the cell and support it structurally
The name of the theory that Schleiden and Schwann developed is the cell theory.
Another name for Schwann cell is neurolemmocyte. Schwann cells are a type of glial cell that provides support and insulation to axons in the peripheral nervous system.
The Schwann cells wrap themselves tightly around the axon like a jellyroll. During the wrapping process, the cytoplasm is squeezed from between adjacent layers of the Schwann cell membranes, so that when the process is completed a tight core of plasma membrane material encompasses the axon. This wrapping is the myelin sheath. The Schwann cell nucleus and the bulk of its cytoplasm end up just beneath the outermost portion of its plasma membrane. This peripheral part of the Schwann cell and its exposed plasma membrane is the neurilemma.
