define neurones

Neurons, also known as nerve cells, are specialized cells that transmit information in the nervous system. They are the building blocks of the nervous system and are responsible for transmitting electrical and chemical signals that allow us to sense, think, and move.

Neurons have a unique structure that enables them to receive and transmit signals. They consist of a cell body, dendrites, and an axon. The dendrites receive signals from other neurons and the axon sends signals to other neurons or cells.

Neurons communicate with each other through specialized connections called synapses. When a signal reaches the end of an axon, it triggers the release of neurotransmitters, which then bind to receptors on the dendrites of neighboring neurons. This triggers a new electrical signal in the receiving neuron, allowing the information to be transmitted from one neuron to the next.
