What are the three major functions of the ANS?
•Regulate heart
•Regulation of secretory glands
•Regulation of smooth muscles
Give the five steps of synaptic transmission.
Steps:
•Synthesis
•Storage
•Release
•Receptor Action
•Termination
Three ways of termination
•Re-uptake
•Enzymatic degradation
•Diffusion away from the gap
What are catecholamines and Non catecholamines?
Catecholamines-It has catechol and amines, and it gives during an emergency.
Non catecholamines- No catechol rings.
Epinephrine is Selective or Non-Selective?
Non-selective
What are the two categories of COPD?

How do you differentiate the cholinergic and myotinic crisis?
Using the Neostigmine (Tensilon) test, it is cholinergic when the patient gets weaker. Myotinic crisis when the patient becomes stronger.
What is Acetylcholinesterase?
It is an enzyme that inactivates or breaks down acetylcholine before reaching organ cells.
What is a Non-Depolarizing Agent?
Medication that has an instant effects
Describe the terms “selective” and “non-selective.”
