A&P 2 Lab Ex: 20 The Autonomic Nervous System Review Sheet
Neostigmine is a drug that is classified as an acetylcholinesterase inhibitor. Explain how neostigmine could reverse the effects of Ogilvie syndrome.
Neostigmine stops aCh-ase from working which results in more ACh being left in the synaptic cleft. This causes the digestive muscles to contract more.
List the names and numbers of the four cranial nerves that the parasympathetic division of the ANS arises from.
Oculomotor nerve (III), Facial nerve (VII), Glossopharangeal nerve (IX), Vagus nerve (X)
Which part of the rami communicates contains nonmyelinated fibers?
gray ramus comunicantes
In which division of the ANS do post ganglionic axons secrete acetylcholine (ACh); cholinergic fibers?
parasympathetic division
Ogilvie syndrome is a condition that mimics a bowel obstruction. The patient experiences abdominal bloating and constipation in the absence of a mechanical blockage. Ogilvie syndrome is usually preceded by surgery and results in extreme loss of mother activity in the bowel. Which division of the ANS is underachieve in this case, especially with respect to the gastrointestinal system?
parasympathetic division
Which division of the ANS arises from cranial and sacral nerves?
parasympathetic division
Which division of the ANS has long preganglionic axon; short postganglionic axon?
parasympathetic division
Which division of the ANS has more specific effects?
parasympathetic division
Which division of the ANS is normally in control?
parasympathetic division
List the names of the two mother neurons of the autonomic nervous system.
preganglionic and postganglionic
In which division of the ANS do post ganglionic axons secrete norepinephrine; adrenergic fibers?
sympathetic division
What division of the ANS has extensive branching of preganglionic axons?
sympathetic division
What division of the ANS has rami communicantes?
sympathetic division
Which division of the ANS arises from spinal nerves T1 through L3
sympathetic division
Which division of the ANS has short preganglionic axon; long postganglionic axon?
sympathetic division
Which division of the ANS is the "Fight or Flight" system?
sympathetic division
List two types of sympathetic ganglia that contain post ganglionic cell bodies.
sympathetic trunk ganglia and collateral ganglia
List two types of parasympathetic ganglia that contain postganglionic cell bodies.
terminal ganglia and intramural ganglia
