General properties and pathways | Divisions of the Autonomic Nervous System | Autonomic and Somatic Pathway | Control | Neurotransmitters and their Receptors |
---|---|---|---|---|
What is the visceral motor system?
another name for the autonomic nervous system
|
What is the sympathetic nervous system?
"fight or flight"
|
What is the somatic pathway?
the pathway where a motor neuron in the brainstem or spinal cord issues myelinated axon that reaches to a skeletal muscle
|
What is the cerebral cortex
the part of the nervous system that provides a pathway that connects sensory and mental experiences to the ANS
|
What is a beta receptor?
type of adrenergic receptors that cause inhibitory effects
|
What is the sympathetic nerve route?
the nerve route in which postganglionic fibers exit through sympathetic nerves that extend to the heart, lungs esophagus, and thoracic blood vessels
|
What is autonomic tone?
the balance between sympathetic tone and parasympathetic tone
|
What is preganlionic and postganglionic
The two types of neurons associated with the autonomic pathway
|
What is dual innervation
when an the innervation or viscera receives fibers from bother the sympathetic and parasympathetic divisions
|
What is norepinephrine?
an stimulate the heart cells(stimulate), but relax the smooth muscles of the respiratory tube to allow more air to pass through (inhibit)
|
What is the parasympathetic nervous system?
the division of the autonomic nervous system that deals with defecation
|
What is the sympathetic nervous system
Has ganglions closer to the CNS
|
What is the oculomotor nerve
The cranial nerve that narrows the pupil and focuses the lense
|
What is vasoconstriction
response to a higher rate of sympathetic nerve firing
|
What is cholinergic?
a receptor that binds ACh
|
What is the splanchnic nerve route
the nerve route in which fibers in spinal nerves T5 to T12 pass through the sympathetic ganglia without synapsing as splanchnic nerves --> collateral ganglia --> preganglionic fibers synapse with postglanglionic fibers
|
What are the lateral horns of the spinal cord (T1-L2)
The origin of presynaptic neurons
|
What is the autonomic pathway?
The pathway that uses norepinephrine
|
What is cooperative effects
when two divisions act on different effectors to produce unified overall effect
|
What is nicotinic?
the cholinergic receptor that has is a ligand gated receptor
|
What is the biofeedback technique?
the technique that trains people to control hypertension, stress, and migraines headaches
|
What is the parasympathetic nervous system
The autonomic nervous system that utilizes ligand gated channel receptors
|
What is the ganglion?
The location that the autonomic pathway synapses
|
What is vasomotor tone?
state of partial constriction
|
What is andrenergic?
adrenalina and norepinephrine binding site (receptor)
