| dentate nucleus of cerebellum | The most lateral and largest of the cerebellar nuclei; it receives the axons of the Purkinje cells of the neocerebellum (lateral areas of cerebellar cortex); together with the more medially located globosus and emboliform nuclei it is the major source of fibres composing the massive superior cerebellar peduncle or brachium conjunctivum. Synonym: nucleus dentatus cerebelli, corpus dentatum, dentatum. (05 Mar 2000) |

| tongue of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| transverse fissure of cerebellum | The cleft caused by the protrusion of the anterior lobe of the cerebellum over the superior and middle cerebellar peduncles. Synonym: fissura transversa cerebelli. (05 Mar 2000) |
| lingula of cerebellum | A tongue-shaped sequence of flattened cerebellar folia forming the anterior (or superior) extreme of the cerebellar vermis, extending forward on the surface of the superior medullary velum between the two emerging superior cerebellar peduncles. Synonym: lingula cerebelli, lingua cerebelli, tongue of cerebellum. (05 Mar 2000) |
| ganglionic | <anatomy> Pertaining to, containing, or consisting of, ganglia or ganglion cells; as, a ganglionic artery; the ganglionic columns of the spinal cord. Origin: Cf. F. Ganglionique. Source: Websters Dictionary (01 Mar 1998) |
| ganglionic blockade | Inhibition of nerve impulse transmission at autonomic ganglionic synapses by drugs such as nicotine or hexamethonium. (05 Mar 2000) |
| ganglionic blockers | Agents having as their major action the interruption of neural transmission at nicotinic receptors on postganglionic autonomic neurons. Because their actions are so broad, including blocking of sympathetic and parasympathetic systems, their therapeutic use has been largely supplanted by more specific drugs. They may still be used in the control of blood pressure in patients with acute dissecting aortic aneurysm and for the induction of hypotension in surgery. (12 Dec 1998) |
| ganglionic blocking agent | An agent that impairs the passage of impulses in autonomic ganglia. (05 Mar 2000) |
| ganglionic branches of lingual nerve | <anatomy, nerve> Motor roots of submandibular ganglion; communicating branches between submandibular ganglion and lingual nerve. Synonym: rami communicantes ganglii submandibularis cum nervo linguali, motor roots of submandibular ganglion. (05 Mar 2000) |
| ganglionic branches of maxillary nerve | <anatomy, nerve> The ganglionic branches, two short sensory branches of the maxillary nerve in the pterygopalatine fossa, the fibres of which pass through the pterygopalatine ganglion without synapse. Synonym: radix sensoria ganglii pterygopalatini, rami ganglionici nervi maxillaris, rami ganglionares, nervi pterygopalatini, nervi sphenopalatini, pterygopalatine nerves, sensory root of pterygopalatine ganglion. (05 Mar 2000) |
| ganglionic branch of internal carotid artery | <anatomy, artery> Branch to trigeminal ganglion; a small branch of the cavernous part of the internal carotid artery to the trigeminal ganglion. Synonym: ramus ganglii trigeminalis. (05 Mar 2000) |
| ganglionic crest | A group of embryonic cells that separate from the neural plate during neurulation and migrate to give several different lineages of adult cells: the spinal and autonomic ganglia, the glial cells of the peripheral nervous system and nonneuronal cells, such as chromaffin cells, melanocytes and some haemopoietic cells. (18 Nov 1997) |
| ganglionic motor neuron | See: motor neuron. (05 Mar 2000) |
| ganglionic saliva | Submaxillary saliva obtained by direct irritation of the gland. (05 Mar 2000) |
| ganglionic stimulants | Agents that mimic neural transmission by stimulation of the nicotinic receptors on postganglionic autonomic neurons. Drugs that indirectly augment ganglionic transmission by increasing the release or slowing the breakdown of acetylcholine or by non-nicotinic effects on postganglionic neurons are not included here nor are the non-specific cholinergic agonists.
