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 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.
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 is impulse conduction?
Party of nervous
A factor that determines the rate of impulse propagation or conduction velocity along an axon?
The speed at which neural impulses are transmitted. Diameter of the axon Degree of myelination of the axon
What is the difference between impulse conduction and transmission?
Impulse conduction refers to passage of impulse within the same cell. Where as transmission as the name implies, is concerned about passage of impulses either chemical or electrical from one cell to another.
If the velocity is constant does that mean that the impulse is the momentum?
impulse = change in momentum so, no
What kind of neurons does impulse conduction occur in the fastest?
nig
What tissue type functions in impulse conduction?
Nervous tissue.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
When current leaps across an insulating myelin sheath from node to node the type of impulse conduction is called what?
Saltatory Conduction
