Question

How are nerve impulses transmitted from one neuron to another neuron?

Answer 1

Nerve impulses:

1. Nerve impulses are electrical signals that travel along dendrites to generate action potentials or nerve impulses.
2. An action potential is caused by the movement of ions in and out of the cell.
3. This specifically includes sodium and potassium ions.

Transmission of nerve impulses:

1. Neurons are the functional unit of the nervous system.
2. They have this amazing ability to detect, receive and transmit a variety of stimuli.
3. These neurons communicate with each other through nerve impulses, which can be understood scientifically.
4. They are usually electrical signals that travel along the axon of the neuron.
5. Neurons communicate with each other at specific points or junctions called synapses.
6. These synapses can be chemical, communicating via chemical messengers or electricity, where ions flow between cells.
7. Hence, the transmission of nerve impulses occurs through synapses.
