What two cell populations make up nervous tissue? What is the function of each?

Neurons are the primary signaling cells of nervous tissue responsible for transmitting electrical impulses. They process and communicate information through their dendrites, cell body, and axon, enabling functions like sensation, movement, and cognition.

Neuroglia are supportive cells in nervous tissue that provide structural support, protection, and nourishment to neurons. They maintain homeostasis, form myelin, and assist in repair and immune defense within the nervous system.

The two cell populations work together: neurons handle communication and signal transmission, while neuroglia support and maintain the environment necessary for neurons to function effectively. This collaboration ensures proper nervous system operation.
