Question
Answer
What is autonomous?   outside of our voluntary conscious control  
🗑
What is semi-autonomous?   have both conscious and involuntary components  
🗑
What are the motor targets for PNS and ANS?   skeletal muscle  
🗑
What is the autonomic targets for PNS and ANS?   smooth muscle, cardiac muscle, and glands  
🗑
Explain motor portions of efferent pathway:   has no ganglia, one myelinated axon to target  
🗑
Explain autonomic portion of efferent pathway:   2 neuron pathway, neuron1 = preganglionic with soma in CNS, Neuron 2= postganglionic with soma in autonomic ganglion  
🗑
Which ganglionics are myelinated and unmyelinated?   preganglionics = myelinated, postganglionics = unmyelinated  
🗑
What does the autonomic nervous system innervate?   smooth muscle, cardiac muscle, glands, visceral organs  
🗑
What is the autonomic nervous system regulated by?   higher brain structures  
🗑
What is the principle organizing center for ANS activity?   hypothalamus  
🗑
What does the axons that connect the hypothalamus to the autonomic nuclei and gray matter?   dorsal longitudinal fasciculus (DLF)  
🗑
Where does the axons of the DLF synapse?   parasympathetic nuclei of CN 3,7,9,10 , intermediolateral cell column of spinal cord, sacral autonomic cells of spinal cord  
🗑
How do autonomics innervate their targets?   indirectly by a 2 neuron chain  
🗑
Where is the cell body and axon of Neuron 1 of ANS located?   cell body in CNS axon terminates in cell body of neuron 2  
🗑
Where is the cell body and axon of neuron 2 in the ANS?   cell body outside CNS in PNS, axon terminates on target organ  
🗑
What are the two primary divisions of ANS and what are their function?   sympathetic= fight or flight, parasympathetic= rest and digest  
🗑
What are the neurotransmitters of sympathetic system?   preganglionic=acetylcholine, postganglionic=norepinephrine  
🗑
What are the neurotransmitters of PNS?   pre and post ganglionic= acetylcholine  
🗑
Where are preganglionic neurons located in PNS?   CN3,7,9,10 ,spinal cord, sacral 2-4  
🗑
Where are preganglionic neurons are located for SNS?   T1-L2  
🗑
Where are the SNS preganglionic neuron somata located?   intermediolateral cell column in thoracic and upper 2 lumbar segments of spinal cord  
🗑
Where do the SNS preganglionic axons exit spinal cord and how do they travel?   thoracic and lumbar nerves, from spinal nerves to sympathetic chain via white ramus  
🗑
Do all SNS preganglionics synapse in the sympathetic chain?   No some passout of the chain to synapse on their target  
🗑
What happens after axons from sympathetic chain exit ganglia?   rejoin spinal nerves via grey ramus  
🗑
What are the sympathetic postganglionic neurons located?   sympathetic chain, ganglia in abdomen (celiac, superior mesenteric, inferior mesenteric), adrenal medulla  
🗑
Explain the character of preganglionic fibers:   generally short, postganglionic neurons located away from target organ  
🗑
What does activation of the SNS cause?   fight or flight (increased HR, decreased peristalsis, increased BP, dilation of coronary arteries, dilation of bronchioles, shunting of blood from gut to skeletal muscle, dilation of pupils  
🗑
What would cause a systemic response?   pain, strong emotion like rage or fear  
🗑
Where are the preganglionic neurons of the PNS located?   CN nuclei 3,7,9,10 , and sacral segements 2-4, this compilation is known as cranial sacral outflow  
🗑
What is the character of parasympathetic preganglionic and post ganglionic fibers?   generally long preganglionics with posteriorganglionics near the target organ so they are short  
🗑
What does the activation of PNS cause?   rest and digest (decreased CO, decreased BP, increased peristalsis, contraction of bladder, papillary constriction  
🗑
Are C fibers myelinated or unmyelinated?   unmyelinated  
🗑
Which side of the brain is Wernike’s area?   almost always on the left  
🗑
