Dual innervation means that visceral effectors are innervated by preganglionic axons from both parasympathetic and sympathetic (ANS) divisions. A. True B False

Cell bodies of the sympathetic preganglionic neurons are part of ...

Which of the following could be used to describe the parasympathetic nervous system? Select all that apply. Short preganglionic, long postganglionic fibers. O long preganglionic, short postganglionic fibers. Known to be active during "rest and digest" responses. Stimulates ciliary muscles of the eye, which makes the lens bulge for close vision. O Active during "fight or flight" responses. increases heart rate « Previous Next

2) Fill in the chart below on the anatomical differences between sympathetic and parasympathetic systems. Sympathetic Parasympathetic Origin Length of Fibers Location of ganglia Preganglionic Neurotransmitters Postganglionic Neurotransmitters

What causes the membrane potential to steadily depolarize to threshold with no ANS input? (please let answer be short. 3-4 sentences should suffice)

Which sentence is accurate? Postganglionic and preganglionic fibers located in the sympathetic division are the same length. Postganglionic and preganglionic fibers in the parasympathetic are the same length. Postganglionic fibers are known to be shorter than preganglionic fibers in the sympathetic division. Postganglionic fibers are known to be shorter than preganglionic fibers in the parasympathetic division.

Describe how depolarisation of a preganglionic parasympathetic neuron leads to the autonomic regulation of an effector organ (e.g. sinoatrial node).

Compare and contrast the organization of the parasympathetic and sympathetic divisions.

The ANS is subdivided into sympathetic and parasympathetic divisions. Review the differences between these two divisions by filling in the table below: Characteristic Sympathetic or Parasympathetic?
