Sympathetic division
thoracolumbar division , active during the times of stress, exertion , or emergency
Parasympathetic division
called craniosacral division, active during resting conditions
enteric nervous system
the nervous system of the digestive tract
visceral reflexes
sympathetic division consists of
Preganglionic neurons between T1 and L2
Neuronal cell bodies in ganglia near the vertebral column
Sympathetic chain ganglia
Collateral ganglia
Specialized neurons in the interior of the suprarenal gland
sympathetic chain ganglia
paravertebral ganglia or lateral ganglia
neck , head , walls limbs , and thoracic cavity
preganglionic neuron
cell bodies are in the lateral gray horns . axons enter the ventral roots
collateral ganglia
-prevertebral ganglia
-neurons innervate effectors in the abdominopelvic cavity
specialized neurons
Modified sympathetic ganglion in the suprarenal gland
Neurons release neurotransmitters that act like hormones
cervical chain
postganalionic
thoracic chain
both pre and post ganglionic neurons
Lumbar chain
postganglionic
sacral chain
postganglionic
coccygeal chain
postganglionic
celiac ganglion
Innervates stomach, duodenum, liver, gallbladder, pancreas, spleen, and kidney
superior mesenteric ganglion
Innervates small intestine and initial segments of large intestine
inferior mesenteric ganglion
Innervates terminal portions of large intestine, the kidney, urinary bladder, and sex organs
suprarenal medulla
epinephrine( adrenal) and norepinephrine
sympathetic ganglion fibers release acetylcholine at the synapse with ganglionic neurons
cholinergic synapses
stimulation of ganglionic neuron causes the release of norepinephrine at neuroeffector junctions
adrenergic
two classes of plasmalemma receptors
alpha & beta
alpha receptor
norepinephrine & epi
beta receptors
epinephrine
