Neurons are specialized cells that make up the nervous system. They are responsible for transmitting information throughout the body, allowing for communication between different organs, tissues, and parts of the brain.
Here's how neurons work:
* Receive Signals: Neurons receive signals from other neurons or sensory receptors.
* Transmit Signals: They convert these signals into electrical impulses that travel along their axons (long, slender projections).
* Send Signals: The electrical impulse reaches the end of the axon, where it triggers the release of neurotransmitters (chemical messengers) into the synapse (the gap between neurons).
* Relay Information: The neurotransmitters bind to receptors on the next neuron, continuing the signal transmission.
This process allows for rapid communication throughout the body, enabling us to think, feel, move, and react to our environment.
