| What is included in the nervous system structurally? | Brain, spinal cord, nerves |
| What are the universal listeners of neuron impulse? | Dendrites |
| What are the universal senders of neuron impulse? | Axon |
| What do we call the area where 2 neurons meet? | Synapse |
| What is the myelin sheath covering the axon of a neuron in the PNS? | Schwann cells |
| What are the gaps between the myelin sheath of a neuron in the PNS? | Nodes of ranvier |
| How do action potentials move to the next neuron? | Neurotransmitters |
| The lobes of the brain are found in which brain region? | Cerebrum |
| What separated the lobes of the brain? | Fissures |
| Where is the thalamus located? | Diecephalon |
| Where does the spinal cord attach to the brain? | Medulla oblongata |
| What 3 parts make up the brain stem? | Pons, medulla oblongata, mid brain |
| What does the cerebellum do? | Coordinates movement |
| What is the job of the hypothalamus? | Autonomic response |
| Olfactory? | Smell |
| Optic? | Vision and detection of light by pupil |
| Oculomotor? | Eye movement up, down, in; pupils respond to light |
| Trochlear? | Eye movement down and in |
| Trigeminal? | Facial sensation and chewing |
| Abducent? | Side to side eye movement |
| Facial? | Facial expression and taste in front 2/3 of tongue |
| Vestibulocochlear? | Hearing and balance |
| Glossopharyngeal? | Swallowing, gag reflex, and speech |
| Vagus? | Swallowing, gag reflex, and speech; control of muscle in internal organs |

| Hypoglossal? | Tongue movement |
| 4 lobes of the brain? | Frontal, Temporal, Occipital, and Parietal |
| Whats the difference between a neuron and neuroglia? | Neuroglia is support cells for the neuron. Neurons are the nerve cells. Neurons cannot divide but Neuroglia can divide. |
| How does the nervous system and another system maintain homeostasis? | If you get cold outside, sensors from the nervous system pick this up. The nervous system sends signals to the musculatory system. The signals sent tell the musculatory system to start shivering the muscles. |
