What causes a nerve impulse move along the nerve fiber?
Electrical diferences.
What cause a nerve impulse move along the nerve fiber?
Electrical diferences.
Why are cathodal pulses required to stimulate a nerve?
Because the negative pulse mimics the effect of an action potential, depolarising the nerve. Therefore propogating the AP along the nerve
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 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 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 are mircroscopic fiber that carries the nervous impulse along a nerve cell?
axon
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.
How do nerves utilize electricity in the human body?
Nerves in the human body use electricity to transmit signals. When a nerve cell is stimulated, it generates an electrical impulse that travels along the nerve fiber. This electrical signal allows communication between different parts of the body, enabling functions like movement, sensation, and coordination.
Where are the cells that make up the pacemaker?
Those cells are nerve cells, the brain sends electrical pulses down and the electricity causes the heart to beat.
What is TENS?
TENS stands for Transcutaneous Electrical Nerve Stimulation. In TENS therapy, electrical devices are used to send stimulating pulses across the surface of the skin and along the nerve strands.
What is required to maintain nerve fiber sheath?
