Effects on organs
"Fight or flight"
Thoracolumbar division
Axon action
Neurotransmitters
100
Pupils do this.
What is dilates?
100
These receptors cause blood vessels to vasoconstrict.
What is Alpha?
100
This "short" fiber connects closest to the spine.
What is the preganglionic fiber?
100
These are drugs that bind to beta receptors and block the binding of norepinephrine and epinephrine.
What is beta blockers?
100
These are chemicals by which the neurons communicate.
What are neurotransmitters?
200
Erect hair muscles are also called this.
What is arrector pilli?
200
Bronchodilation occurs when this receptor is hit.
What is Beta 2?
200
These are the three main receptors of the sympathetic nervous system.
What is alpha, beta 1, and beta 2?
200
The preganglionic neuron synapses with this second efferent neuron.
What is postganglionic?
200
Acetylcholine is broken down by this enzyme.
What is cholinesterase?
300
When a patient is having an asthma attack, the SNS does this to the lungs.
What is bronchodilation?
300
True or false. The sympathetic responses effect one organ system at a time. Explain why or why not.
What is false. Many organs are affected at once.
300
There are this number of sympathetic chain ganglia on each side of the vertebral column.
What is 22?
300
Axons leave the spinal cord and extend to sympathetic ganglia via these.
What are dendrites and somas?
300
This neurotransmitter closes the gap between the post ganglion and the effector.
What is norepinephrine?
400
Of all glands discussed, this reaction occurs only to the salivary glands.
What is decreased secretion?
400
This type of drug is given to try to mimic the effects of the sympathetic nervous system.
What are sympathomimetics?
400
Preganglionic fibers may take up to this many paths once inside the sympathetic chain ganglion.
What is three paths?
400
In the SNS, this gland increases epinephrine secretion.
What is the adrenal medulla?
400
Acetylcholine has this effect on the receptors in the sympathetic nervous system.
What is no effect?
500
This increases when norepinephrine hits Beta 1.
What is increased heart rate/ stronger contractions?
500
These two physiological changes, among others, take place in "fight or flight".
What is conversion of glycogen to glucose and dilation of blood vessels?
500
The sympathetic division has also been 'referred to' as the thoracolumbar division for this reason.
What are dendrites and cell bodies within the lateral gray horns of the thoracic and lumbar segments of the spinal cord?
500
True or false. Post ganglionic fibers always contains the myelin sheath.
What is false?
500
These create norepinephrine.
What are adrenergic fibers?
