5. (6 pts.) The acetylcholine receptors are known as ligand gated ion channels that are generally excitatory. What ion is allowed to pass through when acetylcholine binds to these channels? What is the ligand in this example? 6. (4 pts,) Compare and contrast the sympathetic and parasympathetic divisions of the nervous system. Include similarities and differences in function and physical components. In your current psychological and physical state, which division is most active?

Step 1
When acetylcholine (ACh) binds to the acetylcholine receptors, it allows the passage of sodium (Na+) ions through the channel. In this example, the ligand is acetylcholine itself, as it is the molecule that binds to the receptor and triggers the opening of the ion Show more…

5. For the motor (efferent ) division, distinguish between the somatic and autonomic nervous systems. Include the subdivisions of the ANS. 6. What is the function of a neuron? 7. Give the location (PNS or CNS) and function of: astrocytes, oligodendrocytes, microglia, ependymal cells, Schwann cells and satellite cells. 8. Describe the structure of a neuron. Include: soma, dendrites, axon, myelin sheath. 9. What are anterograde and retrograde movement? 10. What are gray and white matter?
What is similar about the Autonomic and Somatic Nervous Systems? Both have smooth muscle as effectors Both have skeletal muscle as effectors Both can send information to the Central Nervous System through afferent neural pathways Both are part of the Efferent (Motor) Division of the Nervous System Which part of a neuron contains ligand-gated receptors that neurotransmitters could bind to? Dendrites Axon hillock Axon terminals Axon
