At school, you read, remember, walk, balance, feel thirsty-and pull your hand from a hot object. One network links them all: the brain, spinal cord, and nerves. Its regions are forebrain, midbrain, and hindbrain. The cerebrum supports thinking, memory, learning, emotions, and voluntary actions. The hypothalamus regulates hunger, thirst, and temperature. The cerebellum supports balance and coordination; the medulla helps control breathing and heartbeat. The thalamus and pons are regions. Touching the hot object shows a reflex action: receptor, sensory neuron, spinal cord, motor neuron, muscle. The spinal cord responds first; the brain becomes aware of pain afterward. Inside a neuron, signals travel from dendrite to cell body, axon, and nerve ending. Across the synapse, neurotransmitters pass it onward. So your school day reveals the brain's role: not just thinking, but controlling, coordinating, and communicating. Remember: the brain controls, coordinates and integrates the activities of our body.
