Regina Doersom Unit 08 – Autonomic Nervous System Worksheet Watch the videos and answer the questions (please type your answers in Blue or Red): https://youtu.be/tGCfEzozjEs 1. What is the highest control center of the autonomic motor neurons? Hypothalamus 2. What the two types of autonomic motors neurons called? Preganglionic neuron, postganglionic neuron. Parasympathetic and sympathetic nervous system (Was not sure what the question is asking) 3. What is the concept of duel innervation? Connected, while one system has a change in one direction the other causes a change in the other, internal organs are inter-connected by two types of autonomic motor neurons the parasympathetic and sympathetic nervous system. The parasympathetic nervous system performs rest and digest and the sympathetic nervous system works the fight or flight 4. Which division is activated by stress situations? Sympathetic nervous system 5. Which nerves contain parasympathetic neurons? Cranial- III, VII, IX, X Sacral- S2, S3, S4 6. Which nerves contain sympathetic neurons? Dorsal- T1-T12 Lumbar- L2, L3 7. Where do somatic motor neurons originate? From CNS direct axons to skeletal muscles 8. What kind of receptor do somatic motor neurons stimulate when they released acetylcholine? ACh-receptors in muscle fiber, motor neurons tell the skeletal muscle fibers to contract 9. How many neurons does the ANS always use to send a signal to an internal organ? Two 10. What is the first neuron called? Preganglionic neuron 11. What is the second neuron called? Postganglionic neuron 12. What are the acetylcholine receptors on the heart and other internal organs called? Muscarinic receptor 13. What does the postganglionic neuron of the sympathetic neuron release? Release either Ach or NE, so it releases both but depends on what will happen 14. Which cranial nerve has the most parasympathetic neurons? VII 15. Is there a parasympathetic innervation to the adrenal gland? No

What is the entire point of the sympathetic response? Prepares the body for intense physical activity "fight or flight" 4. Which division of the ANS raises blood sugar and oxygen? Sympathetic division 5. Which division of the ANS promote mucus secretion and iris constriction? Parasympathetic division 6. How can norepinephrine dilate some blood vessels and constrict others? exerts effects by binding to α- and β-adrenergic receptors in different tissues https://youtu.be/nPQ2UYVm4Rg 1. How can imagine a stress state? By the E situations 2. What does the parasympathetic nervous system do to the blood sugar? Decrease it 3. What does the parasympathetic nervous system do to the blood flow to the digestive system? Increases the blood flow 4. Does the parasympathetic nervous system promote anabolic or catabolic reactions? Catabolic reactions 5. What kinds of receptors does albuterol situate? It increases heart rate, stimulates the beta2 adrenergic receptors in the lungs 6. What does atenolol do? Lower blood pressure, it’s a beta blocker, blocks the 7. sympathetic response, blocks only the beta one adrenergic receptor sites 8. What kinds of receptors are blocked by MTC cold medications? Blocks the parasympathetic receptors
