‖ morphoˈgenesis
[mod.L., f. Gr. µορϕ-ή form + γένεσις origin: see genesis.]
a. The origination of morphological characters; morphogeny.
1890Century Dict., Morphogenesis. 1899Jrnl. R. Microsc. Soc. 469 Factors in morphogenesis. 1936P. D. F. Murray Bones i. 16 These experiments evidently exclude all functional factors as important agents in primary skeletal morphogenesis. 1951Nature 18 Aug. 301/2 Isolated terminal growing points..afford excellent material for the investigation of the relation between nutrition and morphogenesis. 1974Sci. Amer. Dec. 44/3 They [sc. hydras] have a strong capacity for regenerating lost parts, so that one can study morphogenesis not only in developing animals but also in regenerating ones.
b. Geomorphol. The formation of landscapes or land forms.
1958Geol. Mag. XCV. 126 Tricart and Cailleux..claim that a ‘sufficiently dense cover of vegetation’ interferes very significantly with morphogenesis. 1966J. A. Mabbutt in G. H. Dury Essays in Geomorphol. 102 The hillfoot zone is..very sensitive to climatically-induced changes of morphogenesis. 1968R. W. Fairbridge Encycl. Geomorphol. 130/1 An allied form of morphogenesis rather similarly planes, aggrades and deranges drainage in areas of continental glaciation.
So morphogeˈnetic a., of or pertaining to morphogenesis; morphogeˈnetically adv., as regards morphogenesis.
1884Q. Jrnl. Microsc. Sci. XXX. 98 A direct morphogenetic change in the ganglion cells. 1897Westm. Gaz. 20 July 9/2 The force of gravitation is..the first morphogenetic factor in the individual development of animals. 1905Jrnl. Exper. Zool. II. 155 It seemed to me scarcely possible that all of these strikingly different kinds of oöplasm, each with its own peculiar developmental history and destiny, were nevertheless morphogenetically alike. 1932J. S. Huxley Probl. Relative Growth iv. 117 Each such region would be characterized both by the possession of its own growth-gradient and its own morphogenetic field. 1950Ann. Assoc. Amer. Geographers XL. 214 Recently Büdel (1944, 1948) has suggested the recognition of ‘formkreisen’ or ‘morphogenetic regions’. Ibid. 232 Within an area in which the climate is essentially homogeneous, the geomorphic effects of climate may be assumed to be similar. These areas are here called morphogenetic regions. 1954W. D. Thornbury Princ. Geomorphol. iii. 63 The concept of a morphogenetic region is that under a certain set of climatic conditions particular geomorphic processes will predominate and hence will give to the landscape of the region characteristics that will set it off from those of other areas developed under different climatic conditions. 1957[see field n. 17 c]. 1965Science 29 Oct. 627/3 (caption) Possible relation of collagen distribution to morphogenetically active and inactive areas. 1966Saunders & Fallon in M. Locke Major Probl. Developmental Biol. 289 Death of cells is a normal component of most morphogenetic movements such as foldings, detachments, and the confluence of anlagen. 1969Oikos Suppl. XII. 68 (heading) Morphogenetic aspects of the agrarian landscape of Öland. |
