Term
| What does ANS and SNS stand for? Give names. Tell what each does. |
|
Definition
Autonomic Nervous System
-innervates all organs under the direct control of the CNS except skeletal muscle. |
|
|
Term
| Have a general idea when humans became aware of the physiological phenomean controlled by the ANS. |
|
Definition
| Humans were aware of the sympathetic response of the variouse body organs long before recorded history began. In the earliest written records, of which the bible is amond the oldest, there are accounts of how pain, injury and stress affected: heart rate, sweating, digestive system, pupil of eye, tear production, other body functions. |
|
|
Term
| List four physiological concepts/phenomena that were first discovered or proposed as a theory by physiologists studying the ANS. |
|
Definition
| Homeostasis, adaptation to changes in our external environment, adaptation to changes in our internal enviroment, total body response to stress, the idea of specific receptors for chemical messengers, other physiological phenomena. |
|
|
Term
| List the three types of cells/tissues innervated by the ANS. |
|
Definition
| Smooth muscle, cardiac muscle, gland cells |
|
|
Term
| List the only major organ(s) not under ANS control. |
|
Definition
|
|
Term
| We have seen that one cannot live without the ANS unless ther person was lying down in a controlled environment, being fed through veins with no stress of any kind. List the three major things the ANS does. |
|
Definition
-to maintain homeostasis of our internal environment.
-for adjusting to external environment.
-to organize visceral support for somatic behavior |
|
|
Term
| Be able to explain what is meant by "organizing visceral support for somatic behavior" |
|
Definition
| meaning the internal organs do what is needed to support skeletal muscles activites. |
|
|
Term
| Are we aware of most ANS activities? Explain. Give two or more examples. |
|
Definition
ANS is automatic and mostly subconscious
-homeostasis
-rate of heart |
|
|
Term
| What is the best name for the ANS? |
|
Definition
|
|
Term
| List the two sources of sensory information for the ANS. Be sure you know what both of these do; where each gets it information from. |
|
Definition
| Somatic afferent and visceral afferent |
|
|
Term
Know Neurotransmitter and Receptors on postsynaptic membrane:
Somatic motor neuron |
|
Definition
|
|
Term
Know Neurotransmitter and Receptors on postsynaptic membrane:
P Preganglionic neuron |
|
Definition
|
|
Term
Know Neurotransmitter and Receptors on postsynaptic membrane:
P Postganglionic neuron |
|
Definition
|
|
Term
Know Neurotransmitter and Receptors on postsynaptic membrane:
S Preganglionic neuron |
|
Definition
|
|
Term
Know Neurotransmitter and Receptors on postsynaptic membrane:
S Postganglionic neuron |
|
Definition
|
|
Term
Know origin of sympathic system
Know general action produced by sympathic system
Know when sympathic system will dominate
Know how to deduce effects of sympathic system stimulation. |
|
Definition
|
|
Term
Know origin of parasympathetic system.
Know general action produced by parasympathetic system
Know when parasympathetic sysem will dominate
Know how to deduce effects of parasympatheric system of stimulation. |
|
Definition
|
|
Term
| Is complete P or S dominance common? When do we come the closest to P dominance? To S dominance? |
|
Definition
Rarely do you have complete S or P dominance. Usually we are under partial S and partial P control.
Closest to P dominance when sleeping/relaxed, comfortable, after meal, reading in good light and being "turned on"
Closest to S dominance when about to be killed. |
|
|
Term
| What do we mean by S and P are reciprocal? |
|
Definition
| As the level of one increases, the level of the other decrease. |
|
|
Term
When ACh binds with muscarinic receptors, we may see one of two effects. List these two effects. Tell channels opened to cause each effect. Explain what happens for each one.
|
|
Definition
- Open Na+ chs.
Therefore depolarization.
Therefore smooth muscle will contract
or gland cells will secrete
-Open K+ chs.
Therefore hyperpolarization
Therefore causes inhibition of smooth muscle- thus it will relax
or decrease of gland cells
or S.A node slows heart. |
|
|
Term
| What is atropine? Where does it act? What is its effect? |
|
Definition
