Term
What are the divisions of the ANS?
Definition
sympathetic and parasympathetic divisions
Term
acetylcholine
Definition
A neurotransmitter released by somatic motor nerve fibers, parasympathetic nerve fibers and some other neuron.
Term
ganglion
Definition
is a collection of cell bodies outside the central nervous system.
Term
preganglionic
Definition
Pertaining to a neuron that transmits signals from the CNS to a ganglion
Term
Postganglionic
Definition
Pertaining to a neuron that transmits signals from a ganglion to a more distal target organ
Term
cholinergic
Definition
secrete acetylcholine
Term
adrenergic
Definition
secretes norepinephrine
Term
norephinephrine
Definition
A neurotransmitter secreted by nearly all sympathetic postganglionic neurons
Term
thoracolumbar
Definition
sympathetic division of the ANS
Term
craniosacral
Definition
Parasympathetic division of the ANS
Term
nicotinic
Definition
relating to, resembling, producing, or mediating the effects produced by nicotine on nerve fibers at autonomic ganglia
Term
muscarinic
Definition
relating to, resembling, producing, or mediating the effects (slowed heart rate) that are produced on organs and tissues by acetylcholine released by postganglionic nerve fibers of the parasympathetic nervous system
Term
alpha
Definition
The beginning
Term
beta
Definition
second in order of importance
Term
What is the grey rami communicantes in the sympathetic division?
Definition
One of the ways that unmyelinated postganglionic fibers (transmits signals from ganglion in PNS -> distal target) leave the ganglion. Forms a bridge back to the spinal nerve.
Term
What is the white rami communicantes in the sympathetic division?
Definition
The small myelinated preganglionic (transmits signals from CNS -> ganglion in PNS) fibers travel from the spinal nerve to the ganglion by way of the white communicating ramus.
Term
What is a splanchnic nerve?
