What is the relationship between size of nerve and conduction velocity?
For unmyelinated nerves there is a relationship between axon diameter and conduction velocity. Larger diameter nerves conduct faster. For myelinated nerves the a larger diameter nerve will conduct faster between the nodes of ranvier where the action potential is propagated. Conduction is said to be saltatoryas it jumps from node to node.
Who invented the nerve conduction velocity test?

What is the nerve conduction velocity test?
It measures the ability of the nerve to conduct electrical signals
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
What is nerve conduction velocity test?
A nerve conduction velocity test is a medical procedure used to assess how quickly electrical impulses travel through nerves. It helps diagnose conditions that affect the nervous system, such as nerve damage, neuropathy, and carpal tunnel syndrome, by measuring the speed of nerve signals. The test involves placing electrodes on the skin to stimulate the nerve and recording the response to determine the speed of conduction.
What do nerve conduction velocity studies?
Nerve conduction velocity studies are diagnostic tests that measure the speed at which electrical impulses travel along nerves. They help to evaluate nerve damage, identify specific nerve disorders, and determine the extent and location of nerve injury. These tests are commonly used to diagnose conditions like carpal tunnel syndrome, peripheral neuropathy, and nerve injuries.
How does myelination affect nerve conduction velocity?
Myelination increases nerve conduction velocity by allowing action potentials to "jump" between nodes of Ranvier along the axon, known as saltatory conduction. This speeds up the transmission of electrical impulses along the neuron.
The velocity of nerve impulse conduction is greatest in?
Heavily myelinated, large diameter fibers

How does temperature on a physiological way effect nerve conduction?
Temperature can affect nerve conduction by altering the speed at which nerve impulses travel. Warmer temperatures typically increase the speed of nerve conduction, while cooler temperatures can slow it down. Extreme temperatures can also disrupt the integrity of the nerve cell membrane, impacting nerve conduction.
What is a Nerve conduction velocity test?
A nerve conduction velocity test is a diagnostic procedure used to evaluate the function of nerves by measuring how quickly electrical impulses travel along them. It is commonly used to diagnose nerve damage or disorders such as carpal tunnel syndrome or peripheral neuropathy.
If the position of a nerve was reversed and its conduction velocity recorded would it be the same as if it were not reversed?
Nerve conduction is the same in both directions. The rate of conduction is mediated by the physical properties of the nerve and the voltage sensitive channels so as long as the diameter is constant the spread of the action potential would be the same in either direction.
