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.
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).
Are nerve cells smarter then other cells?
no nerve cells are like a chain one feeels it passes the signal to the next all the way up to your brain
What cells will not continue to divide skin cell nerve cell epithelial cells lining the cheeks all of these?
Nerve cells typically do not continue to divide once they are fully formed. Unlike skin cells and epithelial cells that undergo continuous division for repair and maintenance, nerve cells have limited regenerative capacity. Once nerve cells are damaged or lost, they are not easily replaced, which contributes to the challenges of nerve regeneration in the body.
Why don't all plant cells look the same?
By definition, all human cells are animal cells. Different cells look different from others, no matter the organism. A human nerve looks almost identical to a nerve from a chimp, but a human nerve looks nothing like a cell from a chimp's muscles.
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.
What forms a protective tunnel around the nerve fibers?
neurilemma

What do the bodies of Schwann cells make up?
The neurilemma

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 are the two coverings of a nerve cell?
One is the Myelin Sheath, the other I would assume is the Neurilemma.
The neurilemma of axons in the peripheral nervous system is formed by?
schwann cells
What is the neurilemma and what is it function?
the plasma membrane surrounding a Schwann cell of a myelinated nerve fiber and separating layers of myelin
How are human smooth muscle cells similar to human nerve cells?
All muscle cells and nerve cells use an action potential and also obey the all-or-none law
Is your cell an organism or apart of an organism Nerve Cell?
All your cells are part of you, and you are an organism. Nerve cells are included.
What cells in the peripheral nervous system that form a covering around axons?
Schwann cells wrap around the AXONS of peripheral neurons.
