The video explains the nervous system, which controls our senses and actions. It is divided into the central nervous system, comprising the brain and spinal cord, and the peripheral nervous system, consisting of nerves throughout the body. The brain has three main parts: the cerebrum, cerebellum, and medulla, each responsible for different functions like sensing, movement, and involuntary actions. The peripheral nervous system includes sensory nerves that send information to the brain and motor nerves that carry instructions from the brain. Neurons, the building blocks of nerves, have a nucleus, dendrites, and axons. The video concludes with a mention of additional resources for learning.
