| Flap 1 |
Flap 2 |
| 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 |
