	Autonomic ganglion - Wikipedia, the free encyclopedia
		Ganglia of the sympathetic nervous system deliver information to the body about stress and impending danger, and evokes the familiar fight-or-flight response when activated.
		Neurons of the collateral ganglia, also called the prevertebral ganglia, receive input from the splanchnic nerves and innervate organs of the abdominal and pelvic region.
		Terminal ganglia, or intramural ganglia, are so named because of their close proximity to effector organs and glands.

	SYMPATHETIC SYSTEM - LoveToKnow Article on SYMPATHETIC SYSTEM
		The sympathetic is that part of the autonomic system which is connected with the spinal roots from the second thoracic to the second lumbar inclusive (man).
		Its ganglia are divided by anatomists into the vertebral, those which lie,as a double chain on the ventral face of the vertebral column, and those which lie scattered at various distances among the viscera, the pre-vertebral.
		The cranial autonomic nerves to the heart pass via the vagus nerves and lessen the beating of the heart both as to rate and force.

		The central ganglia are arranged in two vertical rows, one on either side of the middle line, situated partly in front and partly at the sides of the vertebral column.
		In the neck the ganglia lie in front of the transverse processes of the vertebræ; in the thoracic region in front of the heads of the ribs; in the lumbar region on the sides of the vertebral bodies; and in the sacral region in front of the sacrum.
		The ciliary, sphenopalatine, otic, and submaxillary ganglia which are found on the branches of the trigeminal nerve are formed by groups of cells which have migrated from the part of the neural crest which gives rise to the semilunar ganglion.

		These results suggest that diabetic autonomic neuropathy is associated with the dysfunction of human pancreatic polypeptide secretion and that evaluation of his response to test meal may be a sensitive and simple method for the assessment of parasympathetic impairment in diabetics..
		The aim of this study was to assess the effect of blocking the axonal transport of sensory neuropeptides, by local injection of colchicine at pelvic ganglia level, on the sensory and efferent functions mediated by capsaicin-sensitive primary afferent neurons innervating the rat urinary bladder.
		Bilateral injection of colchicine in the prostatic tissue underneath the pelvic ganglia of male rats induced a time-dependent reduction (maximal at 72 h, 100% reduction) of the in vitro contraction of the bladder strips induced by capsaicin (1 microM).

		The cranial outflow components are four pairs of ganglia and the plexuses associated with the vagus nerve.
		A visceral autonomic reflex arc consists of a receptor, sensory neuron, association neuron, autonomic motor neurons, and visceral effector.
		Autonomic dysreflexia is an exaggerated response of the sympathetic division of the ANS that occurs in about 80% of individuals with spinal cord injury at or above the level of T6.

	Ganglion - Wikipedia, the free encyclopedia
		An interconnected group of ganglia is called a plexus.
		There are two major groups of ganglia: spinal ganglia and autonomic ganglia.
		In the autonomic nervous system, fibers extending from the CNS to the ganglion are known as preganglionic fibers, while those from the ganglion to the effector organ are called postganglionic fibers.

		Autonomic neurons are distributed to smooth muscle and cardiac muscle, errector pili muscle, and myoepithelial cells.
		Terminal ganglia are found within or near the various internal organs are associated with cranial nerve X, and spinal cord segments S2-S4.
		These terminal ganglia form the extensive ganglionated plexuses of Auerbach (myenteric) and Meissner (submucosal), which extend the entire length of the digestive tube and are composed of many small aggregates of ganglion cells interconnected by delicate fiber bundles.

	The Autonomic Nervous System
		There are usually 21 or 22 pairs of these ganglia: 3 in the cervical region, 10 to 11 in the thoracic region, 4 in the lumbar region, 4 in the sacral region, and a single, unpaired ganglion lying in front of the coccyx called the ganglion impar.
		The thoracic sympathetic ganglia innervate the trunk region, and the lumbar and sacral sympathetic ganglia innervate the pelvic floor and lower limb.
		Preganglionic axons emerging from the brain stem project to parasympathetic ganglia that are located in the head (ciliary, pterygopalatine [also called sphenopalatine], and otic ganglia) or near the heart (cardiac ganglia), embedded in the end organ itself (e.g., the trachea, bronchi, and gastrointestinal tract), or situated a short distance from the urinary bladder (pelvic ganglion).

		Autonomic nerves are composed of two neurons termed the preganglionic and the Postganglionic neuron based on anatomical location relative to the ganglion.
		The preganglionic axon leaves the CNS from the cranial, thoracic, lumbar or sacral regions and synapse in the autonomic ganglia with the cell body of the postganglionic neuron.
		The postganglionic fibres from the 3 upper cervical ganglia of the sympathetic trunk pass to the heart as the cardiac nerves to the cardiac plexus.

		Sympathetic ganglia are found close to the spinal column (paravertebral ganglia) or further distally (prevertebral ganglia), ie usually (but not always, ie terminal sympathetic ganglia in the urinary bladder and rectum) not close to the organs innervated.
		The perikarya of visceral afferents are found in the dorsal root ganglia, or in the sensory ganglia of certain cranial nerves.
		Tlhese ganglia are arranged segmentally, and project to both sympathetic ganglia and peripheral targets such as the heart.

	Neuropathology of human sympathetic autonomic ganglia. (Site not responding. Last check: 2007-11-05)
		The neuropathologic alterations which underlie autonomic nervous system dysfunction in aging and in a variety of diseases have been systematically examined in the sympathetic ganglia of a series of 347 autopsied adults and in a review of previously published studies.
		Markedly swollen terminal axons containing neurofilamentous aggregates were found immediately adjacent to the neuronal cell bodies of prevertebral sympathetic ganglia in aging, in diabetes, and, to a lesser extent, in alcoholism.
		The frequency of some pathologic lesions in control populations as a function of age or gender necessitates the careful selection of a relatively large, appropriately matched, control population for comparison with presumed disease-induced ganglionic neuropathology, and emphasizes the importance of quantitative comparisons.

	Cholinergic Transmission
		Autonomic nerves, in contrast to somatic nerves, have an additional synapse between the central nervous system and the innervated structure (end organ).
		Thus, specific blockers are known for cholinergic, muscarinic receptors innervated by postganglionic fibers of the parasympathetic division of the autonomic nervous system, for cholinergic, nicotinic receptors in both sympathetic and parasympathetic ganglia, and for cholinergic nicotinic receptors at the myoneural junction (motor end plates) of the somatic nervous system.
		At the nicotinic receptors in ganglia and at the myoneural junction the accumulation of acetylcholine at first leads to an intensification of cholinergic transmission, but with continued accumulation over time, the nicotinic receptors become desensitized.

		Almost all autonomic pathways to target organs (visceral organs) are composed of 2 neurons.
		Preganglionic nerves leave the spinal cord with spinal nerve trunks and project to post-ganglionic neurons whose cell bodies are in the autonomic ganglia.
		In the generalized pattern of chemical synapses of the autonomic system with effector (target) tissues, the pre-synaptic terminal may exhibit an enlarged "axon varicosity." This means the axon has many fine terminals branching out to the surface of the target organ in the region of innervation.

	Autonomic NS
		The autonomic nervous system is subdivided into two parts; (a) the sympathetic nervous system (the fright, flight, or fight system); and (b) the parasympathetic system (normal body homeostasis system).
		In fact the embryologic origin of all autonomic ganglia is from the neural crest.
		The prevertebral ganglia are associated with the unpaired visceral arteries and located in front of the vertebral column and cemented on the aorta.

	The Autonomic Nervous System
		The autonomic system is usually defined as a motor system that innervates three major types of tissue: cardiac muscle, smooth muscle, and glands.
