What is a neurolemma and why is it important?
A neurolemma is the outer membrane of a Schwann cell or nerve cell that plays a crucial role in the regeneration of damaged peripheral nerves. It provides structural support and guidance for regenerating axons, helping them reconnect and restore function after injury.
Can a nerve Cell replace itself after injury?
One of two thing can happen (depending on just how damaged). If it is a sensory nerve, that will not carry sensory impulses to the CNS. You may have a numb feeling in a small area or a very large area. If it is a motor nerve, you may not be able to move a muscle (or a group of muscles). That really is paralyzed means.
How is sodium pumped out of a nerve cell?
Sodium is pumped out of a nerve cell through the action of the sodium-potassium pump, which uses energy in the form of ATP to actively transport sodium ions out of the cell and potassium ions into the cell. This process helps maintain the cell's resting membrane potential and is crucial for nerve cell function.
A human liver cell is very different in a structure and function from a nerve cell in the same person this is best explained by the fact?
A.different genes function in each type of cell
How can you use cell in a sentence?
Nerve cells are a part of the nervous system. There are nerve cells all around the body. Without nerve cells your body would not function the way it does.
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 neurilemma and what is it function?
the plasma membrane surrounding a Schwann cell of a myelinated nerve fiber and separating layers of myelin
What are the two coverings of a nerve cell?
One is the Myelin Sheath, the other I would assume is the Neurilemma.
Regeneration of a nerve fiber in the pns is possible if?
Regeneration of a nerve fiber in the peripheral nervous system (PNS) is possible if the cell body of the nerve remains intact and the nerve fibers are only partially damaged. In this case, the Schwann cells in the PNS can guide the regrowth of the nerve fibers. However, regeneration is a slow process and may not always result in full recovery of function.
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.
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 is a neurolemma and why is it important?
A neurolemma is the outer membrane of a Schwann cell or nerve cell that plays a crucial role in the regeneration of damaged peripheral nerves. It provides structural support and guidance for regenerating axons, helping them reconnect and restore function after injury.
What is the explanation for the nucleus in a nerve cell?
Chemical control center and data repository. It has nothing to do with the function of the nerve cell as part of a nerve.
How are neuron and nerve similar in function?
This is just terminology. Neuron = 'nerve cell'
A nerve cell can also be called a(an) .?
A nerve cell cannot also be called a neuroglial cell. A neuroglial cell is a cell that has a primary function of supporting neurons.
Function of a nerve cell?
To send messaged to the brain
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).
