What are the only drugs that are proven to work by altering or decreasing axonal conduction?
Beta 1 Receptor responses:
heart stimulation, increase force of contraction
Beta 2 Receptor responses:
bronchodilation, relaxation of uterine muscle (slow labor)
Functions of the parasympathetic nervous system:
GI motility, slow HR, increase glandular and respiratory secretions, constrict bronchioles, constrict pupils
Functions of the sympathetic nervous system:
increase BP, HR, shunt blood from skin to organs at core, bronchial and pupil dilation, release stored energy
Alpha 1 Receptor responses:
vasculature, vasoconstriction, pupil dilation, ejaculation, contraction of bladder neck and prostrate
Alpha 2 Receptor responses:
located in presynaptic junction, minimal clinical significance
3 Neurotransmitters used by the peripheral nervous system:
acetylcholine, norepinephrine, epinephrine
3 Cholinergic Receptors:
Nicotinic n (neuronal)
Nicotinic m (muscle)
3 Muscarinic (muscle) subtypes:
M1 - Salivary/CNS
M2 - Heart
M3 - Salivary, GI, Bladder and Eye
Nictotinc N, M and Muscarinc
Pupil constriction, increase GI motility & secretions, HR slow down, lungs increase secretions
