How do nerve signals travel from nerve to nerve?

Answer 1

in transmitting a nerve signal such as from your hand to your brain, several neurons are involved. Nerve cells can receive and transmit signals.the dendrites of one neuron are close to the axon of another neuron. The point where neurons meet is called a synapse

Answer 2

This is a very long and hard 1-2 weeks of worth of work and studying to understand but ill try my best.

A neuron consists of the following structures in the following order:dendrites, soma, axon, myelin sheath, and the axon terminal. Then the synapse. The dendrites on a cell recieve a chemical signal potential from recieved neurotransmitters. The potential changes the polarity within the soma by stimulating and opening the sodium ion channels. The cell either hyperpolarizes or depolarizes If it depolarizes an electrical impulse is sent down the axon. The axon is protected by the myelin sheath. The myelin sheath increases the conductivity of the axon allowing the electrical impulse to carry all the way down the axon. When it reaches the end of the axon it travels into the axon terminal, and the terminal buds. The vesicle sacs are then stimulated, which releases neurotransmitters into the synapse. The neurotransmitters then float across the synapse and stimulate the dendrites of the postsynaptic cell, starting the whole process over again with that cell. When enough neurotransmitters have been released, the autoreceptor on the presynaptic cell will be stimulated. Then the neurotrasmitters reuptake into the terminal buds, where they will either be returned to the vesicle sacs for use at a later time (next time the neuron fires), or else they will be destroyed by the MAO enzyme

This is a very simplified version of it and will most likely confuse you but in this limited amout of space it about the best i can do. sorry.

Answer 3

Once electrical pulses reach the gap between the two neurons it becomes a chemical therefore transmitting it into another neuron or to a effectors such as a muscle or a gland

Answer 4

By chemical transmitters and acetylcholine.

Answer 5

Electrical impulses jump between the nerve cells!
