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 do you call the slender nerve fiber?
The slender nerve fiber is called an axon. It is the long, slender projection of a nerve cell that transmits electrical impulses away from the cell body to other neurons, muscles, or glands.
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.
Can a nerve fiber survive without its cell or its axon?
No, a nerve fiber cannot survive without its cell body or axon. The cell body provides nutrients and support to the axon, while the axon is responsible for transmitting signals. Without either of these components, the nerve fiber would no longer function.
What is required to maintain nerve fiber sheath?
required to maintain nerve fiber sheath
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
What is the difference between the contour and magnitude of single nerve fiber and nerve trunk?
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.

What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
What is the site where the muscle fiber and nerve fiber meet called?
Well of course they meet at the neuromuscular junction

What process is called a nerve fiber?
Dendrites
What affects the speed of nerve transmission and how is it measured?
The speed of nerve transmission can be affected by factors such as the myelination of the nerve fiber, temperature, and the diameter of the nerve fiber. It is measured using techniques such as nerve conduction studies, where electrodes are placed on the skin to measure the speed of electrical impulses along a nerve.
What are tiny pulses of electricity that move along a nerve fiber?
Nerve signals Thats what my crossword was.
How to calculate the speed of propagation of the nerve impulse in a nerve fiber?
The velocity of nerve conduction is usually assessed by dissecting out a nerve fiber from an animal such as a frog. The nerve is placed in a chamber containing stimulating and recording electrodes. The responses of the nerve can be monitored using an oscilloscope. More detail on this procedure can be found in the related link.
