Nerve conduction velocity (CV) is an important aspect of nerve conduction studies. It is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include; age, sex, and various medical conditions. NERVE IMPULSES   The functions of neuron are irritability and conduction. Irritability is the response of an organism to the stimulus. Conduction is the transmission of nerve impulse through the neurons of sensory and motor nerves. The external stimuli are light, temperature, chemicals, electri A nerve impulse is the electric signals that pass along the dendrites to generate a nerve impulse or an action potential.

Conduction of nerve impulses is the only function of the nerve. Nerve fibers can be excited at any part along their length and can conduct impulses in both directions. Action potential does not decrease in strength with distance.

Tap to unmute. If playback doesn't begin shortly, try restarting your Diseases like multiple sclerosis cause degeneration of the myelin, which slows action potential conduction because axon areas are no longer insulated so the current leaks. Figure \(\PageIndex{1}\): Action potential travel along a neuronal axon : The action potential is conducted down the axon as the axon membrane depolarizes, then repolarizes.


The Axoplasm or Depolarization (Action Potential ):. Any stimulus beyond the threshold can initiate an impulse.

Saltatory conduction is faster because the action potential basically jumps from one node to the next (saltare = “to leap”), and the new influx of Na + renews the depolarized membrane. Along with the myelination of the axon, the diameter of the axon can influence the speed of conduction.

Nerve impulse conduction

The speed of conduction of a nerve impulse is affected by multiple factors. Nerve conduction is characteristically abnormal in motor and sensory fibers and in the upper and lower extremities. Conduction velocity of motor fibers is decreased below the normal range by approximately 20%.

Action Potential - The Resting Membrane Potential Understanding the Transmission of Nerve  Like other local anesthetics, the drug decreases the permeability of neuronal membranes to sodium ions, blocking both initiation and conduction of nerve impulses  Contains components of the conduction system Impulse Conduction through the Heart.

factor which has been overlooked, namely the co-transmission by multiple signaling molecules and nerve pulse synchronization in the myometrium have been suggested. together play a key role in the conduction of nervous impulses, maintenance of acid-base balance, implementation of water-salt metabolism. av JH Jang · Citerat av 1 — the otolith, and the inferior vestibular nerve and central connections are intact The tests were performed using air-conduction tone bursts. using the rotational chair test and/or video head impulse test would be needed.
