Autonomic Pharmacology 1 Flashcards
what does efferent doc
signals away from CNS
what does afferent dp
signals to CNS
what are the subdivisions of the PNS
somatic efferent
enteric
autonomic
somatic an visceral afferent
what is somatic efferent
efferent out to skeletal muscle
what are the div of autonomic
symp
parasymp
where is enteric system
in walls of GI tract not as many neurones
what is the role of autonomic NS
carry output from CNS to whole body with exception of skeletal muscle
what are the functions of ANS
visceral functions - involuntary
degree of conscious control ANS functions
simp and parasymp functions
what are some visceral functions involuntary
contraction and relaxation of smooth muscle
all exocrine and endocrine secretions
the heartbeat
aspects of metabolism
what does paarsymp do in general
coordinates body basic homeostatic functions
what does symp do in general
coordinates body fight or flight
what si the basic organisation of ANS
2 neurones in series
one pregang cell body in CNS to post gang
what is an example of an effector cell
cardiac or smooth muscle cell
secretory cell
what is the preganglionic neurotransmitter in ANS
always ACh
what are the diff postganglionic neurotransmitters in ANS
symp - Noradrenaline
parasymp - ACh
where is the outflow from for CNS
cranial and sacral
where is the outflow from from spinal cord
thoracic or lumbar outflow
