Nervous tissue is a specialized type of tissue that makes up the brain, spinal cord, and nerves throughout the body. It is primarily composed of two main cell types: neurons, which transmit signals, and glial cells, which support and protect the neurons. This tissue plays a crucial role in controlling and coordinating bodily functions by sending and receiving electrical impulses. The primary function of nervous tissue is to facilitate communication within the body. Neurons communicate with each other and with other types of cells, allowing us to respond to stimuli, think, and move. Without nervous tissue, our bodies would not be able to process information or react to the environment effectively.
