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.
What nerves carry signals to and from the eyes and ears?
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
What is neural signal?
It is the explanation of signal transfer along a nerve cell or neuron.
The rods and cones send signal to the brain along a thick nerve called the?
Optical nerve
What is the speed of a satellite signal?
A satellite signal will be a radio signal. And a radio signal in space travels at the speed of light.
If a nerve signal travels to and from the brain at a speed of 30 meters per second how long would it take the signal to travel 3 meters?
It would take the signal 0.1 seconds to travel 3 metres, given the parameters that you have given.
The nerve impulse travels as an electric charge and as it nears the synapse it becomes?
A chemical signal.
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.
Which travels faster an digital video signal or audio signal?
Depends. If they're all encoded for transfer by electronic means(radio, fiber, wire) they'll all travel at the same speed. But if you by audio signal mean sound in the air, then sound travels at about 700 miles an hour. A digital signal - electrical/optical - travels at the speed of light (186,282 miles per second) down a fiber network.
What signal travels along the axon?
The high-speed signals that pass along the axon are called action potentials. They spread in a wave of depolarization.
How quickly does the signal travel when a text is sent between phones?
The signal of a text being sent between two pones travels at a speed of 186,282 miles per second.
What nerves carry signals to and from the eyes and ears?
The oculomotor nerve or the third cranial nerve, trochlear or forth cranial nerve and abducent or the sixth cranial nerve carry signal to your eye. The optic nerve carry the signal from the eye to the brain. Vestibulocochlear or the eighth cranial nerve carry the signal from your ear to the brain.
Why cardiac pain referred to left arm and neck?
There is a nerve which connects all three, so when felt in the heart the signal travels to these other areas
Can a radio signal be heard years after being sent?
Yes, if you're far enough away from its source. (Radio travels at the speed of light.)
Which travels quicker through the body a nerve impulse or a hormons?
a nerve impulse
Why does myelination create speed?
This question could probably be asked more clearly. Myelinization of a nerve fiber helps the nerve's signalpropagate more quickly. Think of the nerve cell as a length of wire, and the myelin as the rubber insulation on the wire. Each nerve cell allows an electrical signal to pass down it's axon. If there is insulation around the nerve (myelin) then the signal is contained within the nerve cell, and passes quickly to the end of the nerve cell. Demyelinated nerve cells do not have this insulation keeping the electrical signal in the cell; so the signal can travel to adjacent cells. The net effect is that the signal either never reaches the end of the intended axon (such as with multiple sclerosis), or the signal takes longer to get there. Some nerve cells (grey matter, for example) are not intended to be myelinated. These cells are designed to act without insulation, so either the signal is supposed to travel to adjacent cells, or it is supposed to take relatively longer to reach the end of the axon.
