| medullary arteries of brain | Branches of the cortical artery's which penetrate to and supply the white matter of the cerebrum. (05 Mar 2000) |
| medullary bone | Areas of bone formation present in the marrow spaces of the long bone's of birds, which serve as a readily mobilised source of calcium for shell formation. (05 Mar 2000) |
| medullary callus | The callus within the medullary cavity of a fractured bone. Synonym: medullary callus. (05 Mar 2000) |
| medullary carcinoma | <tumour> A malignant neoplasm, comparatively soft and brainlike in consistency, that consists chiefly of neoplastic epithelial cells, with only a scant amount of fibrous stroma. (05 Mar 2000) |
| medullary cavity | The marrow cavity in the shaft of a long bone. Synonym: cavitas medullaris, cavum medullare. (05 Mar 2000) |
| medullary centre | The great mass of white matter composing the interior of the cerebral hemisphere; the name refers to the general shape of this white core in horizontal sections of the hemisphere. Synonym: centrum medullare, centrum ovale, medullary centre, semioval centre, Vicq d'Azyr's centrum semiovale, Vieussens' centrum. (05 Mar 2000) |
| medullary chemoreceptor | The chemoreceptor's in or near the ventrolateral surface of the medulla that are stimulated by local acidity. (05 Mar 2000) |
| medullary cone | The tapering lower extremity of the spinal cord. Synonym: conus medullaris. (05 Mar 2000) |
| medullary cords | Cord's of dense lymphoid tissue between the sinuses in the medulla of a lymph node. Synonym: lymph cords. (05 Mar 2000) |
| medullary cystic disease | <disease> A rare hereditary kidney disease characterised by the gradual loss of kidney function due to the presence of cysts in the renal medulla. Symptoms include high urine output (cannot concentrate the urine), weakness, weight loss, nocturia, fatigue and headache. There is no cure and usually progresses from chronic renal failure to end stage renal disease. (27 Sep 1997) |
| medullary cystic kidney disease | <radiology> Mode of inheritance uncertain, usually affects young adults (early 20s), associated with red or blond hair (!!), causes salt wasting, polyuria, azotaemia, affects both kidneys, with progressive disease patients need dialysis or transplant (12 Dec 1998) |
| medullary folds | Synonym: neural folds. (05 Mar 2000) |
| medullary groove | The gutter-like groove formed in the midline of the embryo's dorsal surface by the progressive elevation of the lateral margins of the neural plate; the ultimate dorsal fusion of the margins results in the formation of the neural tube. Synonym: medullary groove. (05 Mar 2000) |
| medullary laminae of thalamus | Layers of myelinated fibres that appear on transverse sections of the thalamus; the lamina medullaris externa marks the ventral and lateral borders of the thalamus and delimits it from the subthalamus and reticular nucleus of thalamus; the lamina medullaris interna is interposed between the mediodorsal and ventral nuclei of the thalamus and encloses the intralaminar nuclei (centromedian, paracentral, and central lateral nuclei). Synonym: laminae medullares thalami, medullary layers of thalamus. (05 Mar 2000) |
