Desegmentation
Desegmentation De*seg`men*ta"tion, n. (Anat.) The loss or obliteration of division into segments; as, a desegmentation of the body.
Segmental
Segmental Seg*men"tal, a. 1. Relating to, or being, a segment. 2. (Anat. & Zo["o]l.) (a) Of or pertaining to the segments of animals; as, a segmental duct; segmental papill[ae]. (b) Of or pertaining to the segmental organs. Segmental duct (Anat.), the primitive duct of the embryonic excretory organs which gives rise to the Wolffian duct and ureter; the pronephric duct. Segmental organs. (a) (Anat.) The embryonic excretory organs of vertebrates, consisting primarily of the segmental tubes and segmental ducts. (b) (Zo["o]l.) The tubular excretory organs, a pair of which often occur in each of several segments in annelids. They serve as renal organs, and often, also, as oviducts and sperm ducts. See Illust. under Sipunculacea. Segmental tubes (Anat.), the tubes which primarily open into the segmental duct, some of which become the urinary tubules of the adult.

Segmentation
Segmentation Seg`men*ta"tion, n. The act or process of dividing into segments; specifically (Biol.), a self-division into segments as a result of growth; cell cleavage; cell multiplication; endogenous cell formation. Segmentation cavity (Biol.), the cavity formed by the arrangement of the cells in segmentation or cleavage of the ovum; the cavity of the blastosphere. In the gastrula stage, the segmentation cavity in which the mesoblast is formed lies between the entoblast and ectoblast. See Illust. of Invagination. Segmentation nucleus (Biol.), the body formed by fusion of the male and female pronucleus in an impregnated ovum. See the Note under Pronucleus. Segmentation of the ovum, or Egg cleavage (Biol.), the process by which the embryos of all the higher plants and animals are derived from the germ cell. In the simplest case, that of small ova destitute of food yolk, the ovum or egg divides into two similar halves or segments (blastomeres), each of these again divides into two, and so on, thus giving rise to a mass of cells (mulberry mass, or morula), all equal and similar, from the growth and development of which the future animal is to be formed. This constitutes regular segmentation. Quite frequently, however, the equality and regularity of cleavage is interfered with by the presence of food yolk, from which results unequal segmentation. See Holoblastic, Meroblastic, Alecithal, Centrolecithal, Ectolecithal, and Ovum. Segmentation sphere (Biol.), the blastosphere, or morula. See Morula.
