Section 1

Question Answer
Postganglionic neuronPathway from the ganglion to the effector. Cell body located in the ganglion. Unmyelinated
Preganglionic neuronPathway from the CNS to the ganglion, Cell body found in the brain or spinal cord. Myelinated
Sympathetic divisionShort pre and post ganglionic neuron
Parasympathetic divisonLong pre and post ganglionic neuron
Sympathetic NS is also calledFlight or fight response
Parasympathetic NS is also calledRest and digest
Sympathetic trunk ganglia is locatedon vertical row on either side of spinal column
Prevertebral ganglia is locatedanterior to vertebral column close to abdomen
Ganglia in the PSNS is locatedterminal ganglia close to or within the wall of the visceral effector

Section 2

Question Answer
Celiac innervatestomach, pancreas, liver
Superior mesentericsmall intestine, little of large intestine
Inferior mesentericdistal end of colon
Aorticorenal and renalkidney
Superior cervical head and heart
middle and inferior gangliaheart, blood vessels of neck, should, upper limb
ThoracicThoracic blood vessels, heart, lungs, brochial tree
Terminal ganglion of the headCiliary, pterygopalatine, submandibular, otic ganglion
Cardiac plexusHeart
Pulmonary plexusLungs
Celiac (solar) plexusDigestive system

Section 3

Question Answer
Neurons of the SNS get from the spinal cord to the sympathetic trunk ganglia via theWhite ramus and the axons are myelinated
Neurons of the SNS get from the sympathetic trunk ganglia to their effort via theGrey ramus and the axons are unmyelinated
Define autonomic plexusa tangled network of axons
Greater splachnic nerveBlood vessels to spleen and major digestive organs not colon
Lesser splachnic nerveBlood vessels small intestine, proximal colon
Least splachnic nervekideny, arterioles, ureters
Lumbar splachnic nervedistal colon. rectum. urinary bladder, genitals
What is the role of the adrenal medulla in the ANSRelease epinephrine and norepinephrine
Epinephrine is a horomone
norepinephrine is a neurotransmitter

Section 4

Question Answer
Ciliary ganglionCN III smooth muscle of eyeball
Pterygopalatine ganglionCN VII nasal mucosa, lacrimal gland
Submandibular ganglionFacial nerve submandibular, sublingual glands
Otic ganglionGlossopharyngeal nerver, parotid gland
Thorax CN X suppliesHeart and lungs
Abdominal CN X suppliesMajor GI organs
Sacral outflow of PSNSS2 to S4 via pelvic splanchnic nerves. innervates urinary and reproductive tract

Section 5

Question Answer
Define enteric divisionspecialized network of nerves and ganglia located in wall of GI tract, pancreas, and gall bladder
Which plexuses are found in enteric divisionMyenteric plexus, submuscosal plexus
Where do nerves exit spinal cord in the SNSAnterior root
Where do nerves exit spinal cord in the PSNSBrain, sacral, spinal cord
