What is nerve conduction velocity test?
Nerve conduction velocity test-- A test that measures the time it takes a nerve impulse to travel a specific distance over the nerve after electronic stimulation.
Who invented the nerve conduction velocity test?

What is a Nerve conduction velocity test?
A test that measures the time it takes a nerve impulse to travel a specific distance over the nerve after electronic stimulation.
What do nerve conduction velocity studies?
Nerve conduction velocity studies (NCV) are used to measure the speed with which an electrical signal is transferred along the nerve.
Does the nerve conduction velocity test produce shocks?
This test may cause mild tingling and discomfort similar to a mild shock from static electricity
What is the relationship between nerve size and conduction velocity?
velocity proportional to square root of diameter
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.
Is the velocity of a nerve impulse greater than electrical conduction's?
yes
The velocity of nerve impulse conduction is greatest in?
Heavily myelinated, large diameter fibers
What is the cost of neurological testing?
Nerve Conduction Velocity scans costs Rs1500/-What_is_the_cost_of_a_Nerve_Conduction_Test
What is electrotonic conduction of a nerve?
is a test commonly used to evaluate function
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.
