Moteriek: Autonoom en Somatisch Zenuwstelsel

7 important questions on Moteriek: Autonoom en Somatisch Zenuwstelsel

When is the parasympathetic nervous system activated and when the sympathetic?

The parasympathetic ns is most active during rest, when it stimulated the digestive system and inhibits the cardiovascular system. The sympathetic ns is most active during activity, it coordinates the fight or flight response.

What is the sympathetic nervous system also known as?

thoracolumbar division of the autonomic nervous system, because of the place where the preganglionic neurons emerge from the lumbar and thoratic part of the spinal cord. 

What are intrinsic neurons?

Located in each ganglion, they modulate the flow of information to the target organs.

What are preganglionic and postganglionic neurons?

The preganglionic neurons travel from the CNS to the ganglia (synapses), the postganglionic neurons travel from the ganglions to the effector organs. Within each ganglion there is thus the axon terminsal of treganglionic neurons and the cell bodies and dentrites of postganglionic neurons. 

Where do the preganglionic neurons originate from??

 the lateral horn in the spinal cord also known as the intermediolateralcell column in the grey matter. 

How is the parasympathetic otherwise know as and why?

Also known as the craniaosacraldivision of the autonomic nervous system because the preganglionic nerves originate either in the brainstem or in the sacral spinal cord. 

What is the most important cranial nerves?

The vagus nerve which originates in the medulla oblongata and innervates much of the vicera, including the lungs, heart, stomach, small intestines and liver. 
The oculomotor nerve which innervates smooth muscles of the eye that control popul size and lens strength. 
The facial nerve which innervates the salivary glands.
The glossopharyngeal nerve which innervates smooth muscle and glands of the throat and the viscera of the thorax and abdomen.
