| spherocyte | A small, spherical red blood cell. Origin: sphero-+ G. Kytos, cell (05 Mar 2000) |
| spherocytes | A small, globular, completely haemoglobinated erythrocyte without the usual central pallor, found characteristically in hereditary spherocytosis (spherocytosis, hereditary) but also observed in acquired haemolytic anaemia (anaemia, haemolytic). (12 Dec 1998) |
| spherocytic anaemia | <haematology> A hereditary disorder that leads to a chronic haemolytic anaemia due to an abnormality in the red blood cell membrane. This disorder is caused by a defective gene. Red cells are resistant to stress and rupture easily. Infants may appear jaundiced and pale. Fatigue, weakness and shortness of breath are other symptoms that may be seen in older patients. The spleen may also be enlarged. Treatment includes splenectomy (removal of the spleen). After this is accomplished the life-span of the red blood cells returns to normal. (27 Sep 1997) |
| spherocytic jaundice | Haemolytic jaundice associated with spherocytosis. (05 Mar 2000) |
| spherocytosis | <haematology> A condition in which erythrocytes lose their biconcave shape and become spherical. It occurs as cells age and is also found in individuals with abnormal cytoskeletal proteins, (hereditary spherocytosis, a disorder that leads to haemolytic anaemia). (18 Nov 1997) |
| spherocytosis, hereditary | A familial congenital haemolytic anaemia characterised by numerous abnormally shaped erythrocytes which are generally spheroidal. The erythrocytes have increased osmotic fragility and are abnormally permeable to sodium ions. (12 Dec 1998) |
| spherograph | An instrument for facilitating the practical use of spherics in navigation and astronomy, being constructed of two cardboards containing various circles, and turning upon each other in such a manner that any possible spherical triangle may be readily found, and the measures of the parts read off by inspection. Origin: Sphere + -graph. Source: Websters Dictionary (01 Mar 1998) |
| spheroid | Spheroidal Shaped like a sphere. Origin: L. Spheroideus (05 Mar 2000) |
| spheroid articulation | A multiaxial synovial joint in which a more or less extensive sphere on the head of one bone fits into a rounded cavity in the other bone, as in the hip joint. Synonym: articulatio spheroidea, articulatio cotylica, cotyloid joint, enarthrodial joint, enarthrosis, socket joint, spheroid articulation, spheroid joint. (05 Mar 2000) |
| spheroid calcification | <radiology> Round/oval subcutaneous calcifications, characteristic of Ehlers-Danlos syndrome (12 Dec 1998) |
