A nerve impulse is a sudden reversal of the electrical charge across the membrane of a resting neuron. The reversal of charge is called an action potential. It begins when the neuron receives a chemical signal from another cell. The signal causes gates in sodium ion channels to open, allowing positive sodium ions to flow back into the cell. Neurons and Nerve Impulses.
Transmission of signals internally between the cells is achieved through a synapse. Nerve conductors comprise relatively higher membrane resistance and low axial resistance. 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. another impulse comes along. The following figure shows transmission of an impulse.

To explain this in more detail let’s take the example of a cholinergic synapse; a synapse that uses the neurotransmitter Acetylcholine. The transmission across a cholinergic synapse can be The results of this study demonstrate that AIT and hypothyroidism can affect the expression of mRNA nerve impulse transmission genes in gene specific manner and that these changes in gene expressions can be playing a role in the development of neurological complications associated with thyroid patho … Read formulas, definitions, laws from Impulse and Its Transmission here.

When the nerve impulse arrives at the synapse, it may cause the release of neurotransmitters, which influence another (postsynaptic) neuron. The postsynaptic neuron may receive inputs from many additional neurons, both excitatory and inhibitory. As an action potential (nerve impulse) travels down an axon there is a change in polarity across the membrane of the axon.

Ions moving across the membrane cause the THE ELECTRO-SALTATORY TRANSMISSION OF THE NERVE IMPULSE AND THE EFFECT OF NARCOSIS UPON THE NERVE FIBER. Ichiji Tasaki. Transmission of an action potential. The nerve impulse is an electrical phenomenon that passes as a wave along the surface membrane of a nerve fiber This electrical transmission of a nerve impulse at a false synapse (ephapse) is readily demonstrated in the laboratory. When responsible for clinical symptoms, neuron is not actively transmitting a nerve impulse, it is in a resting state, ready to transmit a nerve impulse.
