	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 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.

	IX. Neurology. 5e. The Trigeminal Nerve. Gray, Henry. 1918. Anatomy of the Human Body.
		The ciliary ganglion is connected with the ophthalmic nerve; the sphenopalatine ganglion with the maxillary nerve; and the otic and submaxillary ganglia with the mandibular nerve.
		In the sphenopalatine ganglion they form synapses with neurons whose postganglionic axons, vasodilator and secretory fibers, are distributed with the deep branches of the trigeminal to the mucous membrane of the nose, soft palate, tonsils, uvula, roof of the mouth, upper lip and gums, and to the upper part of the pharynx.
		The branch of communication from the lingual to the forepart of the ganglion is by some regarded as a branch of distribution, through which filaments pass from the ganglion to the lingual nerve, and by it are conveyed to the sublingual gland and the tongue.

		A ganglion is a soft tissue mass that most commonly occurs on the wrist in women between 25 and 45 years of age.
		If a ganglion were suspected within the deep structures of the foot a MRI would be useful to identify the size and extent of the mass.
		Aspiration of ganglion fluid is attempted, however, because of the thickness of the fluid it is often difficult to draw the fluid out.

	Ganglion cyst - Wikipedia, the free encyclopedia
		A ganglion cyst is a swelling that often appears on or around joints and tendons in the hand (or sometime feet).
		The exact cause of the formation of ganglion cysts is still unknown.
		If a ganglion cyst is symptomatic, it can be managed by aspiration or surgery.

	Webvision: Morphology and Circuitry of Ganglion cells
		Ganglion cells are larger on average than most preceding retinal interneurons and have large diameter axons capable of passing the electrical signal, in the form of transient spike trains, to the retinal recipient areas of the brain many millimeters or centimeters distant from the retina.
		Ganglion cells with the morphology of G21 and G23 are labelled by retrograde transport of tracers from brain visual centers: G21 from the accessory optic system (Farmer and Rodieck, 1982).
		The commonest ganglion cells types of the primate fovea are the P cells or midget ganglion cells and the bistratified blue-on/yellow-off ganglion cell.

	Ganglion Cyst
		Ganglion cysts are small outpouchings of joint capsule, which is the sleeve of tissue that encloses a joint, or tendon lining tissue if they are found near a tendon.
		A ganglion cyst associated with a tendon is called a tendon sheath ganglion or a retinacular cyst, and is usually a small, very hard, 2-4 mm ball at the base of the finger, on the palm side.
		Ganglions become symptomatic when they grow large enough to be obtrusive, or when they compress surrounding structures causing pain, or rarely they can cause nerve damage from compression.

	Ganglion Cysts- Health Encyclopedia and Reference
		A ganglion develops when a jelly-like substance accumulates in one of two places - a joint capsule or a tendon sheath - and causes it to balloon out.
		If the ganglion is painful, the doctor may be able to relieve the discomfort through surgical or other means, but in most cases the small, harmless lump requires no treatment and has no effect on one's daily activities.
		Surgical treatment involves bursting the ganglion simply by putting pressure on it after puncturing it in several places with a needle or draining the jelly-like contents with a needle.

		Because the ganglion is not cancerous and may disappear in time, the physician may recommend just waiting and watching to make sure that no radical changes occur.
		Activity often causes the ganglion to increase in size, thus increasing the pressure on nerves and causing pain.
		If the ganglion causes significant pain or severely limits your activities, you may choose to have the doctor drain the fluids with a procedure called "aspiration." The doctor will numb the wrist and puncture the cyst with a needle to remove the fluid.

	Medical Problems: Ganglion Cyst
		The most popular theory is that ganglions form after trauma or degeneration of the tissue layer responsible for producing the synovial fluid which normally lubricates the joint or tendon sheath.
		Ganglions may limit motion in the adjacent joints, or produce discomfort from compression or distention of local soft tissues.
		Ganglion cysts arising from the flexor tendon sheath at the base of the finger may produce pain when grasping.

	Ganglions -- Topic Overview
		Ganglions are small sacs (cysts) filled with clear, jellylike fluid that often appear as bumps on the hands and wrists.
		A ganglion can grow out of a joint capsule, which surrounds and protects the joint, or a tendon sheath, which covers the tendon (the ropelike fibers connecting muscle to bone).
		Ganglions may be as small as a seed or larger than a cherry.

	Webvision: Ganglion cell Physiology
		Ganglion cell axons terminate in brain visual centers, principally the lateral geniculate nucleus and the superior colliculus.
		Among the population of ganglion cells, a wide range of sizes is covered, perhaps corresponding to the wide range of object sizes in the visual image.
		So although ganglion cells eagerly stake out their own individual turf in a spatial anatomical sense, the physiological signals they transmit are often plagiarized from common sources, resulting in highly correlated firing patterns among neighboring cells.

		A ganglion is a fluid filled outpouching of the membranes (synovium) that line the wrist joint.
		It is caused by a defect in one of the joint capsules, which allows an outpouching (herniation) of the joint membranes through the defect.
		If a ganglion is sufficiently large, causes pain, or interferes with normal tendon functioning, it can be either aspirated (a needle is inserted into the cyst and the fluid removed) or surgically excised.
