| Axon | The long cellular extension from a neuron that transmits action potentials |
| Action Potential | The impulse that is transmitted through the axon of a neuron. |
| Neurons | The nervous system is made up of nerve cells called |
| Sensory neuron | Transmit impulses from the sense organs (receptors) to the spinal cord |
| Synapse | The gap in between neurons |
| Motor neuron | Transmit impulses from the brain and spinal cord to effectors (muscle or gland) |
| Central Nervous System | Consist of a brain and spinal cord |
| Brain | Is a large mass of neurons located in the cranium (skull) |
| Cerebrum | Center of control for: voluntary body movements, 5 senses, and memory |
| Cerebellum | Coordinates motor activities and aids in maintaining balance |
| Medulla Oblongata | Involuntary activities like breathing and heartbeat |
| Spinal Cord | Extends from the brain and is protected by the vertebrae of the spinal column |
| Peripheral Nervous System | Consists of spinal nerves, cranial nerves, motor neurons and sensory neurons |
| Somatic Nervous System | Consist of nerves that regulate voluntary muscles of the skeleton |
| Autonomic Nervous System | Consists of nerves that regulate involuntary actions like heartbeat and gland secretions |
| Meneges | Tough Connective tissue that surrounds the central nervous system. |
| Meningitis | Inflammation of the membrane that surrounds the brain and spinal cord |
| Acetylcholine | A neurotransmitter in the Sympathetic and Parasympathetic nervous system |
| Frontal Lobe | Responsible for motor control, speech, memory and mood |
| Temporal Lobe | Responsible for hearing, learning and interpretation of speech |
| Parietal Lobe | Responsible for sensory reception |
| Occipital Lobe | Responsible for processing and interpreting visual information |
| Gyri | The bumpy surface or folds of tissue found on the exterior surface of the cerebrum |
| Sulcus | Grooves or furrows on the exterior surface of the cerebrum |
