| confluence of sinuses | A meeting place, at the internal occipital protuberance, of the superior sagittal, straight, occipital, drained by the two transverse sinuses of the dura mater. Synonym: confluens sinuum. (05 Mar 2000) |
|---|---|
| pleural sinuses | Three recesses of the pleural cavity, one behind the sternum and costal cartilages (costomediastinal recess), one between the diaphragm and chest wall (costodiaphragmatic recess), and one between the diaphragm and mediastinum (phrenicomediastinal recess). Synonym: recessus pleurales, pleural sinuses. (05 Mar 2000) |
| cranial sinuses | Large endothelium-lined venous channels situated between the two layers of the dura mater; they are devoid of valves. (12 Dec 1998) |
| pulmonary sinuses | The space at the origin of the pulmonary trunk between the dilated wall of the vessel and each cusp of the pulmonic valve. Synonym: sinus trunci pulmonalis. (05 Mar 2000) |
| septum of frontal sinuses | The bony partition between the right and left frontal sinuses; it is often deflected to one side of the middle line. Synonym: septum sinuum frontalium. (05 Mar 2000) |
| septum of sphenoidal sinuses | The bony partition between the two sphenoidal sinuses, often deflected to one side of the mid line. Synonym: septum sinuum sphenoidalium. (05 Mar 2000) |
| sinuses | Air filled cavities. Examples are the ethmoids, maxillary, frontal and sphenoid sinuses. (27 Sep 1997) |
| sinuses of dura mater | Endothelium-lined venous channels in the dura mater. Synonym: sinus durae matris, cerebral sinuses, cranial sinuses, sinuses of dura mater, venous sinuses. (05 Mar 2000) |
| syndromes of paranasal sinuses | <radiology> Gardner: osteomas, Kartagener: chronic infection, basal cell-nevoid, neurofibromatosis, Down (trisomy 21): hypoplastic frontal, sphenoid, with or without ethmoid, progeria: absent frontal sinuses; dwarf, immature, cleidocranial dysostosis: all sinuses absent/small (12 Dec 1998) |
| dural venous sinuses | Endothelium-lined venous channels in the dura mater. Synonym: sinus durae matris, cerebral sinuses, cranial sinuses, sinuses of dura mater, venous sinuses. (05 Mar 2000) |
| intercavernous sinuses | The anterior and posterior anastomoses between the cavernous sinus's, passing anterior and posterior to the hypophysis and forming, with the cavernous sinuses, the circular sinus. Synonym: sinus intercavernosi, Ridley's sinus. Jugular sinus Sinus jugularis, one of three enlargements of the jugular veins; the external jugular sinus is between the two sets of valves; the internal jugular sinus's are at the origin (superior bulb) and near the termination (inferior bulb). (05 Mar 2000) |
| cancer, malignant melanoma | A skin cancer that begins in cells called melanocytes that can grow together to form benign (not cancerous) moles. A change in size, shape, or colour of a mole can be a sign of melanoma. Melanoma can be cured if detected early, before spread (metastasis) to other areas of the body. Diagnosis is confirmed with a biopsy of the abnormal skin. Sun exposure can cause skin damage that can lead to melanoma. (12 Dec 1998) |
| canine malignant lymphoma | <tumour> A progressive fatal disease of dogs characterised by neoplastic transformation and proliferation of lymphoid cells, usually originating in solid lymphoid organs (lymphosarcoma) or bone marrow (lymphocytic leukaemia). (05 Mar 2000) |
| malignant | <oncology> Tending to become progressively worse and to result in death. Having the properties of anaplasia, invasion and metastasis, said of tumours. Origin: L. Malignans = acting maliciously (18 Nov 1997) |
| malignant anaemia | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
