Nervous system
तंत्रिका तंत्र
In this Class 10 Science topic from Control and Coordination, students learn how the nervous system receives information, processes it, and produces suitable responses. The topic explains the role of neurons, sensory and motor nerves, the brain, spinal cord, and sense organs in coordinating body activities. Students also explore nerve impulses, reflex actions, and how reflex arcs enable quick responses, building a clear understanding of communication and coordination in the human body.
