| squid giant axon | <physiology> Large axons, up to 1mm in diameter, that innervate the mantle of the squid. Because of their large size, many of the pioneering investigations of the mechanisms underlying resting and action potentials in excitable cells were done on these fibres. (10 Mar 1998) |
|---|---|
| subependymal giant cell astrocytoma | <tumour> A rare astrocytoma, frequently located in the wall of the lateral ventricle, comprised of large glial cells with abundant eosinophilic cytoplasm and intermixed elongated astrocytes, associated with tuberous sclerosis. (05 Mar 2000) |
| interstitial giant cell pneumonia | A rare complication of measles, with the postmortem finding of multinucleated giant cells lining alveoli. Synonym: Hecht's pneumonia, interstitial giant cell pneumonia. (05 Mar 2000) |
| Touton giant cell | A xanthoma cell in which the multiple nuclei are grouped around a small island of nonfoamy cytoplasm. (05 Mar 2000) |
| Langhans giant cell | Multinucleate cells formed by fusion of epithelioid macrophages and associated with the central part of early tubercular lesions. Similar to foreign body giant cells, but with the nuclei peripherally located. (18 Nov 1997) |
| Langhans'-type giant cells | Multinucleated giant cell's seen in tuberculosis and other granulomas; the nuclei are arranged in an arciform manner at the periphery of the cell's. Synonym: Langhans'-type giant cells. Synonym: cytotrophoblastic cells. (05 Mar 2000) |
| foreign body giant cell | <pathology> Syncytium formed by the fusion of macrophages in response to an indigestible particle too large to be phagocytosed for example talc, silica or asbestos fibres). There may be as many as 100 nuclei randomly distributed: similar cells but with the nuclei more peripherally located (Langhans cells) are found at the centre of tuberculous lesions. (06 Mar 1998) |
| communicating branches of auriculotemporal nerve to facial nerve | <anatomy, nerve> Branches conveying fibres from the auriculotemporal nerve to the facial nerve. Synonym: rami communicantes nervi auriculotemporalis cum nervo faciali. (05 Mar 2000) |
| communicating branches of lingual nerve to hypoglossal nerve | <anatomy, nerve> Communicating branches between the lingual nerve (from mandibular nerve) and hypoglossal nerve forming a plexus on the hypoglossus muscle. Synonym: rami communicantes nervi lingualis cum nervo hypoglosso. (05 Mar 2000) |
| communicating branch of facial nerve with glossopharyngeal nerve | <anatomy, nerve> A small branch from the digastric branch of the facial nerve to the glossopharyngeal nerve. Synonym: ramus communicans cum nervo glossopharyngeo, Haller's ansa. (05 Mar 2000) |
| communicating branch of glossopharyngeal nerve with auricular branch of vagus nerve | <anatomy, nerve> A small branch of the glossopharyngeal nerve which joins the auricular branch of the vagus, conveying tactile fibres. Synonym: ramus communicans cum nervo glossopharyngeo, ramus communicans nervi glossopharyngei cum ramo auriculari nervi vagalis. (05 Mar 2000) |
| communicating branch of lacrimal nerve with zygomatic nerve | <anatomy, nerve> Nerve branch by which postsynaptic parasympathetic (secretomotor) fibres from the pterygopalatine ganglion are transferred from the zygomatic nerve to the lacrimal nerve (heretofore purely sensory) for distribution to the lacrimal gland. Synonym: ramus communicans nervi lacrimalis cum nervo zygomatico. (05 Mar 2000) |
| communicating branch of median nerve with ulnar nerve | <anatomy, nerve> Branch of median nerve joining the ulnar nerve in the hand; the anterior interosseous branch of the median nerve may also communicate with the ulnar nerve in the proximal forearm. Synonym: ramus communicans nervi mediani cum nervo ulnari. (05 Mar 2000) |
| communicating branch of superior laryngeal nerve with recurrent laryngeal nerve | <anatomy, nerve> Branch of internal branch of superior laryngeal nerve communicating with the recurrent laryngeal nerve in the wall of the laryngopharynx supplying sensory fibres to the latter. Synonym: ramus communicans nervi laryngei recurrentis cum ramo laryngeo interno, ramus communicans nervi laryngei superioris cum nervo laryngeo recurrenti, Galen's anastomosis, Galen's nerve. (05 Mar 2000) |
| abducens nerve | <anatomy, nerve> The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibres to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control. (12 Dec 1998) |
