| sphere | 1. <geometry> A body or space contained under a single surface, which in every part is equally distant from a point within called its center. 2. Hence, any globe or globular body, especially a celestial one, as the sun, a planet, or the earth. "Of celestial bodies, first the sun, A mighty sphere, he framed." (Milton) 3. <astronomy> The apparent surface of the heavens, which is assumed to be spherical and everywhere equally distant, in which the heavenly bodies appear to have their places, and on which the various astronomical circles, as of right ascension and declination, the equator, ecliptic, etc, are conceived to be drawn; an ideal geometrical sphere, with the astronomical and geographical circles in their proper positions on it. In ancient astronomy, one of the concentric and eccentric revolving spherical transparent shells in which the stars, sun, planets, and moon were supposed to be set, and by which they were carried, in such a manner as to produce their apparent motions. 4. <logic> The extension of a general conception, or the totality of the individuals or species to which it may be applied. 5. Circuit or range of action, knowledge, or influence; compass; province; employment; place of existence. "To be called into a huge sphere, and not to be seen to move in 't." (Shak) "Taking her out of the ordinary relations with humanity, and inclosing her in a sphere by herself." (Hawthorne) "Each in his hidden sphere of joy or woe Our hermit spirits dwell." (Keble) 6. Rank; order of society; social positions. 7. An orbit, as of a star; a socket. Armillary sphere, Crystalline sphere, Oblique sphere,. See Armillary, Crystalline,. Doctrine of the sphere, applications of the principles of spherical trigonometry to the properties and relations of the circles of the sphere, and the problems connected with them, in astronomy and geography, as to the latitudes and longitudes, distance and bearing, of places on the earth, and the right ascension and declination, altitude and azimuth, rising and setting, etc, of the heavenly bodies; spherical geometry. Music of the spheres. See Music. Synonym: Globe, orb, circle. See Globe. Origin: OE. Spere, OF. Espere, F. Sphere, L. Sphaera,. Gr. A sphere, a ball. Source: Websters Dictionary (01 Mar 1998) |
| debye sphere | <radiobiology> Sphere around a charged test particle whose radius is equal to the Debye length. (09 Oct 1997) |
| segmentation | <biology> Organisation of the body into repeating units called segments is a common feature of several phyla, for example arthropods and annelids, although the segments arise by very different mechanisms. Segmentation also occurs during embryonic development in vertebrates, for example partition of the mesoderm into somites and is a feature of early CNS development. See: rhombomeres, neuromeres. (18 Nov 1997) |
| segmentation cavity | The cavity in the blastula of a developing embryo. Synonym: blastocoele, cleavage cavity, segmentation cavity. Origin: blasto-+ G. Koilos, hollow (05 Mar 2000) |
| segmentation gene | <molecular biology> Genes required for the establishment of segmentation in the embryo. In Drosophila about 20 such genes are required. A development pattern of the embryo of the fruit fly Drosophila where the embryo looks like a stack of discs. Each disc is a segment, and each segment consists of two compartments (an anterior and posterior). Various parts of the adult fruit fly (wings, legs, eyes, etc.) arise from specific segments. (09 Oct 1997) |
| segmentation nucleus | The compound nucleus in the impregnated ovum, formed by conjugation of the nuclei of the ovum and spermatozoon (female and male pronuclei), the zygote nucleus after it commences the first cleavage division. (05 Mar 2000) |
| segmentation sphere |
The segmented ovum or morula.
