Autonomic Nervous System drugs Flashcards
What are the two divisions of the peripheral nervous system?
Afferent/Sensory
Efferent/Motor
What are the two components of the efferent division of the PNS
Autonomic Nervous System
Somatic Nervous System
The Preganglionic neutron and the postganglionic are the __?
2-Neuron chain
The chemical messenger produced by the CNS and ANS to communicate with each other (either two neurons/neuron to effective organs)
Neurotransmitters
What are the five steps of synaptic transmission?
I. Synthesis of transmitters
II. Storage of transmitters
III. Release of transmitters
IV. Binding of transmitters at receptor sites
V. Termination of transmission
What are the three parts of the fifth step of the synaptic transmission?
V.A. Reuptake the transmitters
V.B. The enzymatic degradation
V.C. Diffusion away from the gap
Identify if the action is Sympa/Parasympa:
-Dilates bronchioles
Sympa
Identify if the action is Sympa/Parasympa:
-Increases salivation
Parasympa
Identify if the action is Sympa/Parasympa:
- Dilates blood vessels
Parasympa
This theory describes how drugs act through receptors by binding to the receptors to initiate a response or prevent a response (Lock and Key theory)
Receptor theory
The drug that produces a response (receptor cells fit the receptor site)
Agonist
The drug that blocks a response (does not give the necessary effects)
Antagonist
The ____ agonist mimics the effects of the epinephrine/the effects of the SNS (sympatholytic). It stimulates adrenergic receptors
Adrenergic
Three categories based on the mechanisms of action of the sympathomimetics:
Direct-acting
Indirect-acting
Mixed-acting
Two categories based on chemical structure of the sympathomimetics:
Cathecolamines
Noncatecholamines
