Explain the Functions of the autonomic nervous system (ANS)

Explain the functions of the autonomic nervous system (ANS). 2. Describe the differences between the somatic and the autonomic (visceral) reflex arcs. 3. Identify autonomic effectors and plexuses giving examples of each. 4. Discuss the specific functions of the sympathetic and parasympathetic divisions.

5. Compare the structures and locations of the parasympathetic ganglia and sympathetic ganglia. 6. Define the following fibers: preganglionic, postganglionic, cholinergic and adrenergic.

7. List the specific neurotransmitters secreted within the ANS. 8. Explain the roles of adrenergif (alpha and beta) receptors and the cholinergic (nicotinic and muscarinic) receptors in the ANS.

9. Compare the physiological responses of the sympathetic and parasympathetic systems on the: heart, lungs, blood vessels, digestive tract, liver, spleen, skeletal muscles, urinary bladder, salivary glands, intrinsic muscles of the cye. 10. Deseribe the role of the hypothalamus and brainstem in controlling the ANS
