| Question | Answer |
|---|---|
| what are the three functions of the nervous system | sensory input,integration, and motor output |
| what is included in the nervous system structurally? | Brain, spinal cord, and nerves |
| What are the universal listeners or receivers of the neuron impulse | dendrites |
| What are the universal talkers or senders of neuron impulse? | axons |
| What do we call the area where two neurons meet | synapse |
| What is the myelin sheath covering the axon of a neuron in the PNS | schwann cells |
| What are gaps between the melib sheath of a neuron in the PNS | nodes of the ranvier |
| How do action potentials move to the next neuron | neurotransmitters |
| The lobes of the brain are found in which brain region | cerebrum |
| what separate the lobes of the brain | fissures and sulci |
| Where is the thalamus located | diencephalon superior to the brainstem |
| where does the spinal cord attach to the brain | medulla oblongata |
| what three parts make up the brain stem | mid brain, pons, and medulla oblongata |
| what does the cerebellum do | voluntary, movements, balance, an posture |
| What is the job of the hypothalamus autonomic response | sympathetic divisions |
| Olfactory | smell |
| Optic | vision and detection |
| Oculomotor | eye movement upward and downward and inward, pupil responds to light |

| Accessory | neck turning and shoulder shrugging |
| Hypoglossal | tongue movement |
| list four lobes | frontal,pareintal,temporal, occitipal |
| what's the difference between neuron and neuroglia | neurons transmit signals, neuroglia supports and protects neurons. |
| How does the nervous system and another system maintain homeostasis | The nervous system and endocrine system maintain homeostasis through rapid and thermal regulation |
| How do we respond so quickly to dangerous stimuli | Reflex areas allow for rapid responses to dangerous stimuli. Neurons, interneurons, and motor neurons. |
