Nervous and Endocrine Systems: Types of Neurons

The video explains the roles of different types of neurons: sensory neurons, interneurons, and motor neurons. It describes how these neurons work together to sense and react to stimuli, such as pain. Sensory receptors in the skin detect stimuli and send messages through sensory neurons to the spinal cord and brain. Interneurons relay these impulses, while motor neurons carry messages from the brain and spinal cord to muscles or glands, causing a reaction. The video concludes with an overview of how messages travel along the nerve network.
