In anatomy, a name generally given to a knot-like enlargement in the course of a nerve. It is applied, however, to organs differing considerably from each other in size, colour, texture, functions, &c. They are divided into glandiform, lymphatic, and nervous. 1. Glandiform ganglions, called also adenoid, vascular, and sanguineous ganglions; blind, aporic, ductless, blood, and vascular glands; glandulae spuriae, &c., are organs of whose functions we are, in general, ignorant; and which have the appearance of glands. They are formed of agglomerated globules, pervaded by blood-vessels surrounded by areolar membrane, and contain a milky or yellowish fluid. To this class belong the spleen, thymus, thyroid, and supra-renal glands. They are, doubtless, concerned in sanguification. 2. Lymphatic ganglions. See Conglobate. 3. Nervous ganglions, Ganglia seu Gangliones seu Nodi seu Noduli Nervorum, Tumores seu Plexus ganglioformes, Plexus glandiformes. Tubercula nodosa Nervorum, Diverticula spirituum animalium. Ganglia of increase, Formative ganglia. Enlargements or knots in the course of a nerve. They belong, in general, to the system of the great sympathetic. One exists on the posterior root of every spinal nerve, and on one cerebral,-the 5th. Bichat regarded them as so many small brains, or centres of nervous action, independent of the encephalon, and intended exclusively for organic life. Being formed by the union of the cerebral and spinal nerves, they may send out the influence of both these nervous centres to the parts to which the nerves proceeding from them are distributed. Ganglia are chiefly composed of vesicular neurine; and appear to be concerned in the formation and dispensation of nerve power.

Same etymon. Emphyma encystis ganglion. A globular, hard, indolent tumour, without change in the colour of the skin; of a size varying from that of a pea, to that of an egg, and always situate in the course of a tendon. The tumour is formed of a viscid, albuminous fluid, contained in a cyst of greater or less thickness. The cyst is sometimes loose; but in the majority of cases it communicates, by a narrow footstalk, with the sheath of a tendon, or even with the synovial capsule of a neighbouring articulation. The causes are generally unknown. The treatment consists in compression, percussion, the use of discutients, extirpation, or incision.
