| Question | Answer |
|---|---|
| sympathetic division | dendrites and cell bodies of sympathetic preganglionic neurons are located in gray matter of thoracic and upper lumbar regions of spinal cord |
| axons leave spinal cord in... | anterior roots of spinal nerves and extend to sympathetic/collateral ganglia |
| what happens when axons arrive at sympathetic/collateral ganglia | synapse w several postganglionic neurons |
| postganglionic neuron axons | extend to spinal or autonomic nerves to terminate in visceral factors |
| chain of sympathetic ganglia is located | in front of and at each side of spinal column |
| funct of sympathetic division | serves as emergency/stress system, controlling visceral effectors during exercise or when emotions are triggered. |
| fight or flight | a group of changes induced by sympathetic control |
| parasympathetic division | parasympathetic preganglionic neurons have gray matter containing dendrites and cell bodies. |
| where is gray matter in parasympathetic division | gray matter is in brainstem and sacral segments of spinal cord |
| where is terminate in parasympathetic ganglia located | in head, thoracic and abdominal cavities close to visceral effectors |
| each parasympathetic preganglionic neuron | synapses w postganglionic neurons to only 1 effector |
| funct of parasympathetic division | controls many visceral factors under normal everyday circumstances |
| parasympathetic division - sympathetic division | parasympathetic counterbalances sympathetic |
