Classify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system.
Classify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic Nervous System Preganglionic axons are generally short Generalized activation is called the fight-or-flight response Neurons leave the CNS in the cranial nerves and sacral regions of the spinal cord Generalized activation is called the rest-or-digest response Postganglionic axons release ACh that binds to muscarinic receptors located on the effectors Postganglionic axons are generally short Short preganglionic axons release ACh that binds to nicotinic receptors located within Neurons leave the CNS from the thoracic and lumbar regions of the spinal cord the Most ganglia lie close to the spinal cord and form two chains of ganglia one on each side of the spinal cord Increases intestinal motility and stimulates intestinal secretion Parasympathetic Nervous System Decreases intestinal motility and inhibits intestinal secretion Long preganglionic axons release ACh that binds to nicotinic receptors located within the ganglia Preganglionic axons are generally long Postganglionic axons are generally long Increases heart rate contractility, and conduction velocity Ganglia lie within, or very close to, innervated organs Decreases heart rate contractility, and conduction velocity Postganglionic axons release NE that binds to adrenergic receptors located on the effectorsExplanation / Answer
SYMPATHETIC SYSTEM
1.Preganglionic axons are generally short
2.Short preganglionic axons release Ach that binds to nicotinic receptors that bind to ganglia.
3.Most ganglia lie close to the spinal cord and firm two chains of ganglia
4.Decreases intestinal motility and inhibits intestinal secretion.
5. Increases heart rate, contractility and conduction.
6. Generalized response is called the fright flight response.
7. Neurons leave the CNS through thoracic and lumbar regions of the cord.
8. Postganglionic axons are long.
9. Post ganglionic axons release NE that binds to the adrenergic receptors.
PARASYMPATHETIC SYSTEM
1. Neurons leave the CNS in the cranial nerves and sacral regions of the cord
2. Postganglionic axons release Ach that binds to the muscarinic receptors.
3.Preganglionic axons are long
4. Decreases heart rate, contractility and conduction.
5. Generalized activation is called rest or digest response.
6. Postganglionic axons are short.
7. Increases intestinal motility and secretion.
8. Long preganglionic axons that release Ach that binds to nicotinic receptors.
9.Ganglia lie close to innervated organs.
