What is the function of nerve tissue?

Nerve tissue has a fundamental role in the body, primarily centered on its ability to carry messages to and from the brain. This involves the transmission of electrical signals, which allows for communication between different parts of the body and coordination of various physiological functions. Nerve cells, or neurons, are specialized for this purpose and are responsible for receiving stimuli and sending impulses that can lead to responses such as movement, sensory perception, and regulation of bodily functions. The supporting cells in nerve tissue, known as glial cells, also play an essential role by protecting and insulating neurons, but it is the function of the neurons themselves that is critical for message transfer. This communication system is vital for maintaining homeostasis and responding to changes in the environment.
