What will increase the rate of conduction of an action potential along a nerve?
Myelinating the nerve
What is the relay station for nerve impulses?
There is no relay station in nerve impulse conduction.
COnduction speed of a nerve fiber would be the fastest in a?
...in a myelinated axon.
How does myelination affect nerve conduction velocity?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining cells. When a neural membrane is depolarized, local currents are set up between positive and negative ions causing membrane conduction. In myelinated fibers, the local currents go from one internode (or node of Ranvier) in between two Schwann cells to the next internode. Thus we have "salutatory conduction" where a neural impulse actually jumps from one internode to the next without being conducted down the entire cell membrane.
What happens during continuous conduction?
In Saltatory conduction, the signal leaps or hops from node of Ranvier to another. It uses less energy and it faster. In continuous conduction, the nerve is bare of myelin, moves in continuous waves and the signal is slower.
What is the major heat transfer mechanism within solids?
conduction
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 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 the conduction of nerve impulses?
Neurons
Where does nerve conduction deafness occur?
Nerve conduction deafness is one of the two types of deafness that can happen. It occurs when there is a break in communication between the nerve cells and the inner ear.
Conduction of nerve impulses is possible because of the?
Conduction of nerve impulses is possible because ions in the extracellular environment versus the ions inside the cell.
What will increase the rate of conduction of an action potential along a nerve?
Myelinating the nerve
Distinguish between valence and conduction electron hence explain the mechanism of electrons heat and heat transfer in conduction?
Why is conduction important?
Can conduction deafness result from a lesion on the cochlear nerve?
Yes the result from a lesion on the cochlear nerve is sensorineural deafness. The result from the fusion of the ossicles is conduction deafness.
What is the relay station for nerve impulses?
There is no relay station in nerve impulse conduction.
What is the nerve conduction velocity test?
It measures the ability of the nerve to conduct electrical signals
Who invented the nerve conduction velocity test?
