| medullary tube | <embryology> The progenitor of the central nervous system. See: neural plate, neurulation. (18 Nov 1997) |
|---|---|
| neoplasms, ductal, lobular, and medullary | Neoplasms, usually carcinoma, located within the centre of an organ or within small lobes, and in the case of the breast, intraductally. The emphasis of the name is on the location of the neoplastic tissue rather than on its histological type. most cancers of this type are located in the breast. (12 Dec 1998) |
| internal medullary lamina | See: medullary laminae of thalamus. (05 Mar 2000) |
| lateral medullary lamina of corpus striatum | A thin, sharply defined layer of fibres separating the putamen from the globus pallidus. Synonym: lamina medullaris lateralis corporis striati. (05 Mar 2000) |
| lateral medullary syndrome | <syndrome> A syndrome due usually to thrombosis, characterised by dysarthria, dysphagia, staggering gait, and vertigo, and marked by hypotonia, incoordination of voluntary movement, nystagmus, Horner's syndrome on the ipsilateral side, and loss of pain and temperature senses on the side of the body opposite to the lesion. Synonym: lateral medullary syndrome, Wallenberg's syndrome. (05 Mar 2000) |
| anterior cranial base | The portion of the internal base of the skull, anterior to the sphenoidal ridges and limbus, in which the frontal lobes of the brain rest. Synonym: fossa cranii anterior, anterior cranial base. (05 Mar 2000) |
| anterior cranial fossa | The portion of the internal base of the skull, anterior to the sphenoidal ridges and limbus, in which the frontal lobes of the brain rest. Synonym: fossa cranii anterior, anterior cranial base. (05 Mar 2000) |
| attached cranial section | Craniotomy with a segment of the calvaria and attached soft tissues turned as a flap to expose the cranial cavity. Synonym: attached cranial section, osteoplastic craniotomy. (05 Mar 2000) |
| middle cranial fossa | A butterfly-shaped portion of the internal base of the skull posterior to the sphenoidal ridges and limbus and anterior to the crests of the petrous part of the temporal bones and dorsum sellae; it lodges the temporal lobes of the brain in the lateral portions, and the hypophysis centrally. Synonym: fossa cranii media. (05 Mar 2000) |
| cranial | <anatomy> Pertaining to the cranium or to the anterior (in animals) or superior (in humans) end of the body. Origin: L. Cranialis (18 Nov 1997) |
| cranial arteritis | <pathology> An inflammatory condition of the temporal artery. It is a serious chronic vascular disease, characterised by inflammation of the walls of the blood vessels (vasculitis). The age of affected patients is usually over 50 years of age. It most often involves the carotid artery system, and can lead to blindness or stroke. It can be diagnosed by biopsy of an artery, but there is often a false negative result. Elevation of the erythrocyte sedimentation rate is typical. Treatment is with high dose steroids. Common symptoms include headaches and tenderness over the temple (temporal artery). Can be associated with polymyalgia rheumatica. See: polymyalgia rheumatica. Synonym: cranial arteritis, temporal arteritis (20 Jun 2000) |
| cranial base | The sloping floor of the cranial cavity. It comprises both the external base of skull (external view) and the internal base of skull (internal view). See: internal base of skull. Synonym: basis cranii, cranial base. (05 Mar 2000) |
| cranial bones | The paired inferior nasal concha, lacrimal, maxilla, nasal, palatine, parietal, temporal, and zygomatic; and the unpaired ethmoid, frontal, occipital, sphenoid, and vomer. Synonym: ossa cranii, cranial bones. (05 Mar 2000) |
| cranial capacity | The cubic content of the skull obtained by determining the cubage of small shot, seeds, or beads required to fill the skull. (05 Mar 2000) |
| cranial cavity | <anatomy> The skull. (16 Dec 1997) |
