-
name the 2 control systems in the body
-
name the 2 division of the the nervous system
- cns - central
- pns - peripheral
-
central nervous system consist of
-
peripheral nervous system consist of
- sensory neurons (towards the nerve)
- somatic motor neurons
- autonomic nervous system
-
autonomic nervous system is consist of
- parasympathetic branch
- sympathetic branch
-
parasympathetic branch =
- controls SLUD
- Salivation
- Lacination
- Urination
- Defication
-
sympathetic branch =
- is NOT essential to life
- fight or flight response -- our body's primitive, automatic, inborn response that prepares the body to "fight" or "flee" from perceived attack, harm or threat to our survival.
-
nerve propagation consist of
- electrical: sa/na pump
- chemical: neurotransmitter-- ach/ne
- acetylcholine: cholinergic
- epi, ne: anticholinergic
-
what is acetylcholine ACH
parasympathetic branch uses ACH to conduct the nerve transmission.
it is the neurotransmitter uses to create SLUD
-
parasympathomimetic:
mimics/stimulates the parasympathetic (slud) nervous system
-dec hr/bronchoconstriction
-
parasympatholytic:
blocks effects of parasympathetic (slud) nervous system
bronchodilation
-
sympatholytic:
blocks effects of sympathetic (fight or flight) nervous system
bronchoconstriction, dec hr
-
sympathomimetic
stimulates/mimics the sympathetic (fight or flight) nervous system
inc fight or flight you get vasoconstriction
-
cholinergic:
stimulates a receptor for ACH
-
adrenergic:
stimulates a receptor for NOREPI, EPI
-
anticholinergic:
blocks ACH
-
antiadrenergic:
blocks NOREPI, EPI
-
sympathetic (adrenergic) receptor sites interacts with
G proteins
