Autonomic Physiology Flashcards
Somatic
voluntary NS
Autonomic
involuntary NS
autonomic divisions
para and sympathetic
fight or flight
sympathetic
rest and digest
parasympathetic
sympathetic NS exits from the spinal cord at
thoracic and lumbar regions
white ramus
preganglionic fibres
grey ramus
postganglionic fibres
Sympathetic
ACh act on cholinergic receptors….
nicotinic
muscarinic
Sympathetic
Noradrenaline (and adrenaline) act on adrenergic receptors…..
alpha and beta
preganglionic fibres release
ACh and acts on nicotinic cholinergic receptors
Postganglionic fibres release
noradrenaline and act on alpha OR beta receptors
parasympathetic NS exits the spinal cord at
sacral and cranial regions
parasympathetic
preganglionic fibres release ACH and act on
nicotinic receptors
parasympathetic
postganglionic fibres release ACh and act on
muscarinic receptors
Sympathetic ganglia lie …. to spinal cord
close
parasympathetic ganglia lie………to spinal cord
close or within
sympathetic have a …….. component
hormonal
