209 Human Anatomy & Physiology II
Chapter 14 - The Autonomic Nervous System
Revised for spring 2008
After
completing this chapter, you should have mastered the objectives listed below.
1.
Define the autonomic nervous system (ANS.)
- Examine Figure 14.1 and explain
the relationship of the ANS to the PNS and CNS.
- Compare the structures and
functions of the autonomic/somatic nervous systems. Include in your
description the terms pre- and post- ganglionic.
- Study Figure 14.2. Review
this material as it was presented beginning on "pages 7 - 11" in
the "Synaptic Transmission" section of the Nervous System II
Interactive Physiology CD. (Also review relevant quiz questions
4a,b and 7 and 8 in that program.) Focus on information about
cholinergic and adrenergic fibers, types of receptors and drugs, etc. that
modify neurotransmitter effects.
2. Compare the structures and functions of the
parasympathetic/sympathetic nervous systems.
- Tell from what general regions of
the spinal cord the parasympathetic/sympathetic nervous systems arise.
(You don't have to know the CNS nuclei involved unless these are
referenced during lecture.)
- Compare the relative lengths of
their pre- and postganglionic fibers.
- Compare the general locations of
the ganglia in each system.
- Tell which neurotransmitters (ACh
and/or NE) are involved
3. Explain
referred pain.
4. State the
effects of the parasympathetic and sympathetic divisions on the following:
heart, blood vessels, gastrointestinal tract, lungs, adrenal medulla and
external genitalia. Explain which of these effects include antagonistic
and/or cooperative interactions of the autonomic divisions.
5. Discuss the
role of sympathetic and parasympathetic tone.
6. Discuss the
unique roles of the sympathetic division.
7. Describe
the effect of biofeedback on autonomic nervous system functioning.
8. Describe
consequences of homeostatic imbalance of the ANS.
- Describe Raynaud's disease and its
treatment.
- Describe autonomic dysreflexia (mass
reflex reaction), its causes and who is most at risk.
- Tell how hypertension is related
to loss of ANS homeostasis.
9. The
A&P Place - review appropriate material.
****I will rely on lecture, lab, and
any or all of the above material when testing on this chapter.****
