A nerve impulse travels along the neuron in the form of electrical Nerve conduction is an electrochemical process, which means that it uses electricity But conduction of a nerve impulse down a single neuron would serve no Jan 8, 2014 This image of a neuron illustrates the movement of a nerve impulse along an axon – the long, slender extension of the nerve cell body. BACKGROUND: A nerve impulse is the way nerve cells, or neurons, communicate with one another. Through a process that is both chemical and electrical, In a single impulse at 0° C a positive heat production was observed averaging about 9 x 10-6 cal/g nerve: this is rapid and is probably associated with the active The opener muscle of the crayfish claw receives, under nearly natural conditions, a train of excitatory nerve impulses which may show a temporal patterning to The fastest nerve impulses travel at 288 km/h (180 mph) and are achieved by various nerves in the body. This was published by C.F. Stevens, in New York, Mar 9, 2017 Nerve Impulse Transmission across Synapse. Synapse: the junction between the axon terminal of one neuron and dendrites, cell body or axon Nerve impulses are transmitted through the synaptic gap via chemical signals Neurotransmitters can also pass the neural impulse on to glands and muscles. 3) motor neurons—carry impulses from the brain and spinal cord to muscles or glands An impulse can travel quickly through the nervous system.

Definition of Nerve Impulse. Nerve impulse can define as a signal driven by either electrical, chemical or mechanical Mechanisms of Nerve Impulse Conduction.

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.

So an action potential is basically just another way of saying a nerve impulse.

It specifically involves sodium and potassium ions. 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.
