What part of the peripheral nervousThe Autonomic Nervous System
system controls internal organs by innervating smooth muscle,
cardiac muscle, and glands in these organs/tissues?
Which type of autonomic neuronPreganglionic neurons: Originate in the
CNS originates somewhere in the central nervous system?
Which type of autonomic neuronPostganglionic neurons: Originate in an
autonomic originates in an autonomic ganglion?ganglion.
, Where are the parasympatheticBrainstem & sacral spinal cord.
preganglionic cell bodies located within the
central nervous system?
Where are the sympatheticThoraco-lumbar spinal cord. preganglionic cell
bodies located within the central nervous system?
Do postganglionic neurons formPostganglionic neurons: Synapse directly with
synapses with other neurons, or dotarget cells in organs, not other neurons.
they synapse with target cells in organs?
Where are the sympathetic gangliaSympathetic ganglia: Near the spinal cord
located? Where are the(sympathetic chain, prevertebral ganglia).
parasympathetic ganglia located?Parasympathetic ganglia: Near or within
target organs.
In general, what are the basicSympathetic: “Fight or flight” — increases heart functions of the
sympathetic and therate, dilates pupils, mobilizes energy.
parasympathetic divisions of theParasympathetic: “Rest and digest” — slows heart,
autonomic nervous system?constricts pupils, promotes digestion.
What are the autonomicPreganglionic → Postganglionic (both divisions): neurotransmitters
involved at eachAcetylcholine (ACh) → nicotinic receptors. different synapse (for
bothPostganglionic → Target cells:
autonomic divisions)?Sympathetic: Mostly norepinephrine (NE); some
ACh (sweat glands).
Parasympathetic: ACh → muscarinic receptors.
