ANS- Sympathetic Division Flashcards
The sympathetic division is also known as:
thoracolumbar division
The cell bodies of the preganglionic neurons of the are located:
lateral gray horns of thoracic and lumbar regions of spinal cord
Axons of the preganglionic neurons exit:
As part of the rami communicantes
Characteristics of preganglionic neurons of the sympathetic division:
Short and myelinated
What neurotransmitter do the preganglionic neurons of the sympathetic division release:
Acetylcholine
Two types of ganglia in the sympathetic nervous system:
1) Prevertebral Ganglia
2) Sympathetic trunk ganglia
Prevertebral ganglia are:
Clumps in front of the vertebra that contain postganglionic cell bodies
Sympathetic trunk ganglia are
bead-like ganglia on each lateral side of the vertebra
Purpose of both types of ganglia
Where the preganglionic and postganglionic neuron synapse
Postganglionic Neurons of the sympathetic division have cell bodies:
in either of the two ganglia
Axons of the postganglionic Neurons of the sympathetic division are:
long and unmyelinated
What neurontransmitter do the postganglionic Neurons of the sympathetic division release?
norepinephrine onto the effectors
