In nerve and muscle cells the membranes are electrically excitable, which means they can change their membrane potential, and this is the basis of the nerve impulse. The sodium and potassium channels in these cells are voltage-gated , which means that they can open and close depending on the voltage across the membrane.
The nerve impulse is a wave of depolarization traveling along the axon of the motor nerve such that the resting membrane potential of about −70 millivolt is reversed, becoming briefly positive. At the nerve terminal, the nerve impulse causes voltage-gated calcium channels at the active zones…. Read More.

In nerve and muscle cells the membranes are electrically excitable, which means they can change their membrane potential, and this is the basis of the nerve impulse. The sodium and potassium channels in these cells are voltage-gated , which means that they can open and close depending on the voltage across the membrane. nerve impulse The wave-like progression of electrical depolarization that passes along a stimulated nerve fibre. The nerve impulse results from a movement of positive and negative ions across the membrane of the fibre. English Ion channels, small holes in the cell membranes which are the key actors in all biological systems, have an important function in nerve impulse control. Nerve impulses are action potentials that move along the length of an axon as a wave of depolarisation.
The dendrites of some neuron detect and receives the impulse from a previous cell, the nerve impulse travels along going from the dendrites to the nucleus than to the axon , and finally to the axon terminal when the impulse is nerve impulse: [ im´puls ] 1. a sudden pushing force. 2.

the electrical discharge that travels along a nerve fiber PTS, tinnitus, impulse noise, solvent, vibration i olika kombinationer. can give rise to slow nerve degeneration and accelerated age-related hearing loss. A nerve impulse is an electrical phenomenon that occurs because of a difference in electrical charge across the plasma membrane of a neuron. The sodium-potassium pump maintains an electrical gradient across the plasma membrane of a neuron when it is not actively transmitting a nerve impulse. A nerve impulse is the electric signals that pass along the dendrites to generate a nerve impulse or an action potential. An action potential is due to the movement of ions in and out of the cell. It specifically involves sodium and potassium ions.

Transmission of Nerve Impulses. The transmission of a nerve impulse along a neuron from one end to the other occurs as a result of electrical changes across the membrane of the neuron. The membrane of an unstimulated neuron is polarized—that is, there is a difference in electrical charge between the outside and inside of the membrane.

late 14c., nerve, nerf, "sinew, tendon, hard cord of the body" (a sense now obsolete), also "fiber or bundle of fibers that convey the capacity to feel or move from the brain or spinal cord to the body," from Old French nerf and directly from Medieval Latin nervus "a nerve," from Latin nervus "sinew, tendon; cord, bowstring, string of a musical instrument," metathesis of pre-Latin Nerve Impulse Content: Nerve Impulse. Definition of Nerve Impulse. Nerve impulse can define as a signal driven by either electrical, chemical or mechanical Mechanisms of Nerve Impulse Conduction. There are two modes of nerve impulse conduction, namely continuous and saltatory 11.4: Nerve Impulses Generating Nerve Impulses. A nerve impulse, like a lightning strike, is an electrical phenomenon. A nerve impulse occurs Action Potential.
Nerve impulses are mostly electrical signals along the dendrites to produce a May 7, 2015 its membrane potential there by transmitting the signal from the neuron the effector cell because nerve impulses move very rapidly down the nerve impulse a wave of depolarization, in the form of an action potential, that is propagated along a neuron or chain of neurons as the means of transmitting Why are eye-foot and eye-hand reaction times different? The brain controls your movement by sending nerve impulses down the nerves to the place in the body Generation and Transmission of the Nerve Impulse. A nerve impulse is generated when the stimulus is strong. This stimulus triggers the electrical and chemical A nervous impulse is an electric signal that transmits messages between the different parts of the body. A communicator. The Your neurons carry messages in the form of electrical signals called nerve impulses. To create a nerve impulse, your neurons have to be excited.
