Question
Classify the following characteristics to demonstrate your knowledge of differences between the sympathetic and parasympathetic divisions of the autonomic nervous system. Sympathetic Nervous System ore ic axons release ACh that binds to nicotinic receptors located within Ganglia lie within, or very close to, innervated organs the rt preganglionic axons Preganglionic axons are generally short release ACh that binds to nicotinic receptors located within Generalized activation is called the rest-or-digest response Neurons leave the CNS from the thoracic and lumbar regions of the spinal cord stganglionic axons release Preganglionic axons are generally long NE that binds to adrenergic receptors located on the Postganglionic axons are generally short Generalized activation is called the fight-or-flight Parasympathetic Nervous System axons release Increases heart rate, contractility, and conduction velocity ACh that binds to muscarinic receptors located on the Postganglionic axons are generally long Neurons leave the CNS in the cranial nerves and sacral regions of the spinal cord Decreases heart rate contractility, and conduction velocity Decreases intestinal motility and inhibits intestinal secretion ganglia to t Increases intestinal motility and stimulates intestinal secretion spinal cord and form two chains of ganglia one on each side of the spinal cordExplanation / Answer
Sympathetic nervous system
1 increases heart rate contraction and conductivity velocity.
2 generalized activation is called Flight or fight response.
3 decreases intestinal motility and inhibits intestinal secretion
4 pre ganglionic axons are generally short
5 neurones leave the CNS lumbar and thoracic region of the spinal cord
6 post ganglionic axons are generally long
7 postganglionic neurones release nor epinephrine that binds to the adrenergic receptor located on the effector
8 post ganglionic axons release a c h that binds to the muscarinic receptors present on the effector
Parasympathetic nervous system
1 long preganglionic axons release ACh that binds to the nicotinic receptors located within the ganglia.
2 post ganglionic exams are generally short.
3 decreases heart rate contraction and conduction velocity
4 increases intestinal motility and increases intestinal secretion
5 ganglia lie within or very close to innernated organ
6 short preganglionic axons release a Ch that binds to the nicotinic receptors located within the ganglia
7 generalized activation is called rest or digest response
8 neurones leave the CNS in the cranial nerves and sacral regions of the spinal cord
9 most ganglia lie close to the spinal cord and forms 2 chains of ganglia one on each side of the spinal cord.
1 thalamus
2 cerebellum
3 brainstem
4 hypothalamus
5 cerebrum
