| 202507952 | Central Nervous System (CNS) | Brain & Spinal Cord | |
| 202507953 | Peripheral Nervous System (PNS) | Sensory Neurons, Motor Neurons, Sense Organs, receptors | |
| 202507954 | Sensory Neuron | Receives info from environment, sends impulses to brain/ spinal cord | |
| 202507955 | Motor Neuron | Carries impulses in brain/ spinal cord to muscles or glands | |
| 202507956 | Nerve Impulse | Electrical message within a neuron, chemical message between neurons | |
| 202507957 | Receptor | Structures in skin and sense organs, senses a change in the environment then sends impulses to sensory neurons | |
| 202507958 | Neurotransmitters | Chemicals that carry a nerve impulse between neurons | |
| 202507959 | Synapse | Space between 2 neurons | |
| 202507960 | Cerebellum (location) | Behind and under cerebrum | |
| 202507961 | Cerebellum (function) | Sends impulses to voluntary muscles, controls coordination, keeps balance and muscle tone | |
| 202507962 | Brain Stem (location) | Extends below cerebrum | |
| 202507963 | Brain Stem (function) | Connects brain and spinal cord, controls involuntary muscles | |
| 202507964 | Cerebrum (location) | Largest part of brain, left/right hemispheres | |
| 202507965 | Cerebrum (function) | Interprets impulses from senses, memory stored, voluntary muscles controlled, thinking | |
| 202507966 | Medulla (location) | small oblong node on the brainstem | |
| 202507967 | Medulla (function) | Controlls basic involuntary functions such as heart rate, breathing, etc. | |
| 202507968 | Stimulant | Class of drugs that increases heart rate, increases nervous system activity | |
| 202507969 | Depressant | Class of drugs that decreases heart rate, decreases nervous system activity | |
| 202507970 | Hallucinogen | Class of drugs that disrupts nervous system activity, mimics schizophrenia and other severe mental illnesses |
