Nervous System Functions and Structures

The video tutorial explains the nervous system, its main parts, and functions. It covers the central nervous system, including the brain and spinal cord, and the peripheral nervous system, detailing neurons and nerve types. The video also describes neuron structures and their role in transmitting messages. A fun fact about the brain's reaction to smell is included.
