QuestionAnswer
origin of preganglionic fiber for the sympathentic system thoracic and lumber regions of spianl cord
origin of postganglionic fiber of sympathetic system sympathetic ganglion chain near spinal cor or collateral ganglia about halfway between spinal cord and effector organs
preganglionic fibers for sympathetic system short cholinergic
postganglinoic fibers in the sympathetic long adrenergic (most) long cholinergic (few)
effector organs that the sympathetic system innervates cardia muscle, almost all smooth muscle most exocrine glands and some endocrine glands
types of receptors for preganglionic neurotransmitters in the sympathetic system nicotinic
type of receptor for postganglionic neurotransmitter in the sympathetic system alpha 1 alpha 2 beta 1 and beta 2
what is the dominate role for the sympathetic division emergency fight or flight situations; prepares body for strenuous physical activity
origin of preganglionic fiber for the PARAsympathentic system brain and sacral region of spinal cord
origin of postganglionic fiber of PARAsympathetic system terminal ganglia (in or near effector organs)
preganglionic fibers for PARAsympathetic system long cholingeric
postganglinoic fibers in the parasympathetic system short cholinergic
effector organs that the sympathetic PARAsystem innervates cardiac muscle, most smooth muscle, most exocrine glands, and some endrocrine glands
types of receptors for preganglionic neurotransmitters in the PARAsympathetic system nicotinic
type of receptor for postganglionic neurotransmitter in the PARAsympathetic system muscarinic
what is the dominate role for the PARAsympathetic division dominates in quiet, relaxed situations; promotes "general housekeeping" activities such as digestion
