| Body system that controls all activities of the body | Nervous system |
| Makes up the central nervous system | Brain and spinal cord |
| Small space between neurons across which an impulse travels | Synapse |
| Impulses going to a nerve cell travel along these feelers or "receivers" | Dendrites |
| Impulses leaving a nerve cell travel along these feelers or "senders" | Axons |
| Main control center of the central nervous system | Brain |
| Part of the brain that controls balance and posture | Cerebellum |
| Part of the brain that controls heartbeat and breathing | Medulla |
| Senses involved in the flavor of the food you eat | Taste & smell |
| Four basic tastes | Sweet, sour, salty & bitter |
| Spinal cord links these together | Brain & all parts of the body |
| Protects the spinal cord | Column of vertebrae (bones) |
| Protects the brain | Skull |
| This is what happens when brain cells die | They stay dead & cannot be replaced |
| Effect of alcohol on the body | Slows down the activity of the central nervous system |
| Effect of caffeine on the body | Speeds up the activity of the central nervous system |
| Part of the brain in which thinking takes place & memory is stored | Cerebrum |
| Cerebrum | Largest part of the brain |
| Nerve cells | Neurons |
| Involuntary and automatic response to a stimulus | Reflex |
| Cerebellum | Part of brain that coordinates voluntary muscle movement |
| Major sensory receptors for taste | Taste buds |
| A fluid filled structure in the inner ear | Cochlea |
| Tissue at the back of the eye that is sensitive to light | Retina |
| System made up of all the nerves outside the brain and spinal cord | Peripheral nervous system |
| Dendrite | Branch part of a neuron that receives messages and sends them to the cell body |
| Axon | Branch part of a neuron that transports messages away from the cell body |
| Reflex | A response caused by the spinal cord interpreting an impulse from sensory receptors |
| Spinal cord | Part of the body made up of bundles of neurons that carry impulses from all parts of the body to the brain and from the brain to all parts of the body |
| Regulation of steady, life-maintaining conditions inside an organism | Homeostasis |
