True or false questions about the brain, senses, and nerves

📚 Quick Study Guide

• 🧠 The Brain: The control center of the body, responsible for thought, memory, emotion, and coordination. Divided into regions like the cerebrum, cerebellum, and brainstem.
• 👁️ Senses: Mechanisms that allow us to perceive the world around us, including sight, hearing, smell, taste, and touch. Each sense relies on specialized receptor cells.
• ⚡ Nerves: Bundles of fibers that transmit electrical and chemical signals between the brain and the rest of the body. Neurons are the fundamental units of the nervous system.
• 🧬 Neurons: Specialized cells that transmit nerve impulses. They consist of a cell body, dendrites (receive signals), and an axon (sends signals).
• 🖐️ Sensory Receptors: Specialized structures that detect stimuli like light, sound, or pressure and convert them into electrical signals.
• 🔄 Synapses: Junctions between neurons where signals are transmitted. Neurotransmitters are released to carry the signal across the gap.
• 🌡️ Homeostasis: The body's ability to maintain a stable internal environment, regulated by the nervous and endocrine systems.
