Microscopic fiber that carries the nervous impulse along a nerve cell?
The microscopic fiber that carries the nervous impulse along a nerve cell is called an axon. Axons are long, slender projections of a nerve cell that transmit electrical signals away from the cell body to other neurons, muscles, or glands. These signals, known as action potentials, travel down the axon through a process called depolarization and repolarization.
Can a nerve fibre survive without its cell?
No, a nerve fiber cannot survive without its cell, as the nerve fiber is an extension of the neuron, which is the cell responsible for its maintenance and function. The neuron provides essential support, including nutrients and electrical signals, necessary for the nerve fiber's survival. If the neuron dies, the nerve fiber will also degenerate and lose its ability to transmit signals.
Why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves?
The reason why a peripheral nerve such as the sciatic nerve can contain nerve fiber from several spinal nerves is owing to nerve plexuses. These are networks of nerves all tangled together and found mostly in the limbs.
What are components of a nerve fiber?
A nerve fiber consists of the axon, which transmits nerve impulses, along with protective covering called myelin sheath, Schwann cells that produce myelin, and the endoneurium which surrounds individual nerve fibers.
What is electrochemical process of depolarization and repolarization along a nerve fiber?
During depolarization, sodium ions rush into the nerve fiber, making the inside more positively charged. This triggers an action potential to be carried along the fiber. Repolarization occurs when potassium ions exit the cell, restoring the original negative charge inside the cell. This process allows the nerve fiber to transmit signals along its length.
What do you call slender nerve fiber?
denorites axon cell body
What is required to maintain nerve fiber sheath?
required to maintain nerve fiber sheath

Mechanism of nerve conduction?
Nerve conduction involves the transmission of electrical impulses along the length of a nerve fiber. When a nerve is stimulated, sodium ions rush into the nerve cell, causing a change in electrical charge. This creates an action potential that travels down the nerve fiber, activating adjacent areas and allowing the signal to be transmitted. Once the impulse reaches its destination, neurotransmitters are released to stimulate the next nerve cell or muscle fiber.
Axon is what?
An axon (or axone) is a nerve fibre which is a long, slender projection of a nerve cell, which conducts nerve impulses away from the body of the cell to a synapse.

What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction
What is an axis cylinder?
An axis cylinder is an obsolete term for an axon - a nerve fibre which is a long slender projection of a nerve cell.
What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
