What is the primary function of neurons?

The primary function of neurons is to transmit electrical signals throughout the body. Neurons are specialized cells that form the basic working unit of the nervous system. They communicate through electrical impulses and chemical signals, allowing for rapid transmission of information between different parts of the body, including the brain, spinal cord, and peripheral nerves. This function is essential for processes such as reflexes, sensation, muscle contraction, and the coordination of complex behaviors.

Neurons possess unique structures, such as dendrites, which receive incoming signals, and axons, which carry impulses away from the cell body to other neurons or target tissues. This specialized signaling capability distinguishes neurons from other cell types that may serve supportive or protective roles, participate in immune responses, or store information in different contexts, but do not directly engage in the transmission of electrical signals.
