World of Biology on Instagram: "Neurons are specialized cells that transmit signals throughout the nervous system. They communicate through synapses, where an electrical impulse triggers the release of neurotransmitters.

This electrochemical communication is essential for brain function, muscle movement, and sensory perception, enabling the body to respond quickly to internal and ext
