Chap 9. Autonomic Nervous System
1. Choose: Sympathetic system, Parasympathetic system, Neiter, or both.
Both
Neither
Control involuntary activity e.g. heart muscle, smooth muscle, or glands.
Innervate to skeletal muscle.
Parasympathetic
Its signal inputs into cranial part and sacral part in spinal column.
Sympathetic
Its signal inputs into Thoracic and lumbar part in spinal column.
Sympathetic
Activates “fight or flight”
Parasympathetic
“Rest, recover, and digestive”
Sympathetic
Increase heart rate.
Parasympathetic
When you eat lunch, this activates.
Parasympathetic
Decrease heart rate
Sympathetic
Neither
While you are taking quiz(or midtermII), this activates.
Both
Is considered motor nervous system
Sympathetic
When you exercise, this activates
Both
Parasympathetic
Medulla oblongata controls this.
Never(or very few) found this nerve in blood vessel, adrenal medulla, sweat glands,
(in other word, the other nerve is mostly found in these organs)
Both
Innervates in the heart.
Both
Release ACh as neurotransmitter.
Sympathetic
Release Norepineprine as neurotransmitter.
Neither
Release Norepineprine as neurotransmitter in preganglionic nerve.
Both
Release ACh as neurotransmitter in preganglionic nerve.
Parasympathetic
Release ACh mostly as neurotransmitter in postganglionic nerve.
Sympathetic
Neither
Innervates in blood vessel, sweat glands, and adrenal medulla.
Consist of one single motor neuron.
Sympathetic
Dilate pupil and dilate air pathway.
Is considered CNS system
2. Based on the answers on question1, fill in the blank.
Characteristic
Sympathetic nervous system
Parasympathetic system
Thoracic, Lumbar
Cranial, sacral
“Fight or flight”
“Rest and recover”
increase
decrease
What does its input go into the
spinal column (cranial,
thoracic, lumbar, sacral)
Activates “fight or flight” or
“rest and recover” response?
(indicate which one in the
space)
Will this system tend to
increase or decrease heart
rate? (consider the answer
SI Bio6 Dr. Wright’s class
given above)
made by Pyeongsug Kim
Revised: 03/20/10
What is the predominant
neurotransmitter released by
Norepineprine
ACh
Salivary gland – decrease
Airway path(bronchioles)- dilation
Mucus gland – inhibition of gland
Salivary gland – increase
Airway path(bronchioles)- constrict
Mucus gland – stimulation of gland
the postganglionic neuron?
Give another example of dual
innervations: indicate which
organ is affected and what is
done by the indicated system
(be sure to indicate the same
organ in both!)
3. Where in the brain is the autonomic nervous system regulated? Medulla oblongata
4. Give two example(name of organ) of single innervations. Indicate which ANS system innervates in each.
Blood vessel- Sympathetic, adrenal medulla- Sympathetic, sweat glands- Sympathetic
5. What is the difference between somatic and autonomic system? (fill in the blank)
Characteristic
Somatic nervous system
Autonomic system
Voluntary
Involuntary
Voluntary? Involuntary?
control
Give an example(tissue or
organ) that each system
Skeletal muscle
cardiac and smooth muscles,
glands
innervates.
Single motor neuron?
Pre-/postganglionic neuron
before it reach the target
Single motor neuron
Pre-/postganglionic neuron
Ach only
Ach and norepinephrine
No
Yes
organ.
Neurotransmitter
Controlled by medulla
oblongata?(Y/N)
6. If a patient has a damage of medulla oblongata, which physiologic function might be affect?
Can’t control breathing, cardiac activity(cardiac rate), and digestive function.
7. Please answer about Sympathetic nervous system.
a. Preganglionic neurons release acetylcoline(ACh), which has a stimulatory effect on the postganglionic neurons.
Do the postganglionic neurons express nicotinic or muscarinic receptor (indicate which)?
Nicotinic receptor because this receptor open Na+ channel and cause EPSP to have the postganglionic neurons to be
stimulated to fire Action potential.
b. Given the “fight or flight” activity of the sympathetic nervous system, what is the effect you would expect to see
when sympathetic system acts on:
1) the heart rate (increase, decrease)?
SI Bio6 Dr. Wright’s class
2) sweat secretion (increase, decrease)?
made by Pyeongsug Kim
Revised: 03/20/10
3) airways in the lungs (get wider or smaller)?
4) Rate of breakdown of stored food molecules (increase, decrease)?
5) The pupil size (increase, decrease).
6) During exercise, the blood vessel in intestine (dilate, constrict) by sympathetic system?
*Accordingly, stimulation of the sympathetic nerve seems to be more effective than catecholamines in supplying
blood glucose by degradation of liver glycogen and muscle glycogen.
c. Indicate whether the following statement applies to the sympathetic or parasympathetic nervous system. It should
be one or the other.
sympathetic
When you enter the dark room, the pupil size increase by this system.
parasympathetic
Release acetylcoline from postganglionic fibers
sympathetic
Also known as the thoracolumbar system.
parasympathetic
parasympathetic
Also known as the craniolsacral system.
Beta-blockers, taken for anxiety or high blood pressure, would interfere with the
effects of this system.
The preganglionic neurons in this system originate in the brain and sacral area of
the spinal cord.
Secretions and motility increased in large intestine.
sympathetic
Increased conversion of glycogen to glucose in the liver.
sympathetic
parasympathetic
Sorry, addional questions for CNS System
1. Name two body functions controlled by the hypothalamus.
Feeding & satiety center; hunger & thirsty; regulate endocrine system
2. Name two structures within the limbic system that are associated with formation of memory.
Hippocampus & amygdala of limbic system located medial temporal lobe.
3. Name two additional sites in the brain where memories are formed and/or stored. Name their types of memories that
are formed at these sites.
1) Left hemisphere: verbal memories; words
2) Right hemisphere: images
3) Temporal lobe (including hippocampus and amygdale) for storage (memory) of auditory and visual experiences.
inferior temporal lobe ~ site for the storage of long term visual memories
4. What is the term of loss of memory? amnesia
