	Ganglion - Wikipedia, the free encyclopedia
		This is a dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody.
		In vertebrate anatomy, a ganglion is a tissue mass that contains the dendrites and cell bodies (or "somata") of nerve cells, in most case ones belonging to the peripheral nervous system.
		In the autonomic nervous system, fibers 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 ganglion - Wikipedia, the free encyclopedia
		Autonomic ganglia are clusters of neuronal cell bodies and their dendrites and are essentially a junction between autonomic nerves originating from the central nervous system and autonomic nerves innervating their target organs in the periphery.
		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.
		Terminal ganglia, or intramural ganglia, are so named because of their close proximity to effector organs and glands.

	Example: Autonomic Reflex Arc (Site not responding. Last check: 2007-10-06)
		As with the somatic arc, this sensory fiber is associated with a pseudounipolar neuron in a craniospinal ganglion, usually one of the dorsal root ganglia.
		In the autonomic arc, the sensory transducer is often located in or associated with visceral organs.
		Autonomic ganglia are "switching stations" in the periphery; here the signal is passed from the first neuron of the motor chain to the second neuron.

	The Autonomic Nervous System (Site not responding. Last check: 2007-10-06)
		The autonomic nervous system (ANS) is the part of the nervous system, both afferent and efferent, that innervates various body systems that are not under voluntary control.
		The superior ganglion sends branches along the internal and external carotid arteries to reach structures in the orbit, face, nasal and oral cavities and pharynx.
		The postganglionic fibres travel in the branches of the ganglion or the maxillary nerve to reach the nasal and palatine glands.

		In the autonomic plexuses of the head, neck, thorax, abdomen and pelvis, the sympathetic and parasympathetic divisions of the Autonomic Nervous System are combined into extensive networks of nerve fibers.

		The autonomic nervous system is a visceromotor system that influences the activities of many visceral functions via its innervation of smooth and cardiac muscles, and exocrine and endocrine glands.
		For instance, the nicotinic receptor of autonomic ganglia is not identical to the nicotinic receptor at the neuromuscular junction.
		Recent evidence suggests that there is a third component of the autonomic nervous system, the enteric nervous system, which consists of a group of intrinsic neurons that are located in and innervate the tissues of the respiratory and digestive systems.

		This is an autonomic ganglion, presented here at the same magnification as the craniospinal ganglion you saw earlier.
		The sympathetic trunk is the long string of ganglia that are lined up along the vertebral column from the base of the skull to the coccyx and connected to the spinal nerves.
		At higher power--and again, this is the same magnification used for the comparable view of the sensory ganglion--you will note that the cells of this ganglion are much smaller than those of the sensory type, and that their nuclei tend to be eccentric in the somata.

		NGF increases significantly the extent and number of dendritic branches on a ganglion cell neuron and it alters the direction of growth of an axon growing in a culture dish.
		Interestingly, the retinal ganglion cells are spontaneously active once they differentiate, and it is this spontaneous activity that is required to refine connections in both the LGN and primary visual cortex.
		The spontaneous activity of the ganglion cells is not random, but waves of activity that pass across the retina are generated.
