Question
Answer
In the 2-neuron series of the ANS, the soma of the first nerve cell is ALWAYS located in:   THE CNS  
🗑
In the 2-neuron series of the ANS, the soma of the first nerve cell is ALWAYS located in:   A GANGLION IN THE PNS  
🗑
The first nerve cell is the pre or postganglionic neuron?   PREGANGLIONIC  
🗑
The second nerve cell is the pre or postganlionic neuron?   POSTGANGLIONIC  
🗑
What does the axon of the preganglionic neuron synapse with?   THE POSTGANGLIONIC NEURON  
🗑
What does the axon of the postganglionic neuron synapse with?   THE TARGET TISSUE  
🗑
Where are the preganglionic sympathetic neuron cell bodies?   LATERAL HORN OF THE SPINAL CORD FROM T1-L2  
🗑
Where are the preganglionic parasympathetic neuron cell bodies?   BRAINSTEM AND LATERAL HORN OF S2-S4  
🗑
Where are postganglionic sympathetic neuron cell bodies?   (MOSTLY) IN THE SYMPATHETIC CHAIN OR PRE-AORTIC GANGLIA  
🗑
Where are postganglionic parasympathetic neuron cell bodies?   IN OR NEAR THE TARGET ORGAN  
🗑
Where do postganglionic sympathetic fibers distribute to?   BODY WALL AND MOST VISCERAL ORGANS  
🗑
Where do postganglionic parasympathetic fibers distribute to?   VISCERAL ORGANS  
🗑
Which system acts more globally, sympathetic or parasympathetic?   SYMPATHETIC  
🗑
Which system is more structured and works on specific target organs, sympathetic or parasympathetic?   PARASYMPATHETIC  
🗑
How is the sympathetic chain ganglia connected to the spinal nerves?   GRAY AND WHITE RAMI COMMUNICANTES  
🗑
Where are the white rami communicantes located?   T1-L2  
🗑
True or false: gray rami communicantes connect only spinal nerves T1-L2 to the sympathetic chain?   FALSE. They connect ALL spinal nerves to the sympathetic chain.  
🗑
What type of fibers are in the vagus nerve?   PREGANGLIONIC PARASYMPATHETIC AND GVA (VISCERAL SENSORY)  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
