Visceral motor pathways
|
2 neuron system
|
|
|
visceral sensory pathways
|
1 neuron system
|
|
|
Sympathetic Division of ANS
|
T1-L2; Thoracolumbar; fight or flight; neurons are short:long
|
|
|
Parasympathetic Division of ANS
|
brain stem or S2-S4; craniosacral; feed or breed; neurons are long:short
|
|
|
Sympathetic innervation of Heart
|
Origin T1-T4; synapse in sympathetic chain, exit via cervical or thoracic sympathetic cardiac nerves.
|
|
|
Parasympathetic innervation of Heart
|
Vagus nerve; synapse in cardiac plexus.
|
|
|
Sensory info from heart
|
pain carried by sympathetic nerves; cardiac reflexes follow PS.
|
|
|
Referred pain
|
CNS perceives visceral pain from heart to be somatic pain from T1-T4 dermatome.
|
|
|
Innervation of lungs
|
Same pattern as heart. T1-T4. Sympathetic Trunk; R and L vagus nerves. Anterior and Posterior pulmonary plexus.
|
|
|
Sympathetic innervation of foregut
|
T5-T9; greater splanchnic nerve synapses in celiac ganglion.
|
|
|
PS innervation of foregut
|
Vagus nerve goes through celiac plexus but synapses in wall of organ.
|
|
|
Sympathetic innervation of midgut and kidney
|
T10-T11, lesser splanchnic nerve synapses in Aorticorenal or Superior Mesenteric Ganglion
|
|
|
PS innervation of midgut
|
Vagus nerve goes through plexus but synapses in organ wall.
|
|
|
Sympathetic innervation of hindgut
|
L1 to L2; lumbar splanchnic nerve synapses in Inferior Mesenteric Ganglion.
|
|
|
PS innervation of hindgut
|
S2-S4; pelvic splanchnic nerves does not go through ganglion. synapses in organ wall.
|
|
|
Innervation of adrenal gland
|
sympathetic is preganglionic neurons from T5-T8.
|
|
|
Sympathetic vs PS innervation
|
PS has no effect on skin or adrenal gland
|
|
|
Splanchnic nerves that exert influence in thorax synapse
|
in sympathetic chain
|
|
|
Splanchnic nerves that exert influence in abdomen synapse
|
in prevertebral ganglion
|
