enchylema Biol.|ɛnkɪˈliːmə|
[G. (J. von Hanstein Das Protoplasma als Träger d. pflanzlichen & thierischen Lebensverrichtungen (1880) iv. 39): see en-2 and chyle.]
In some old theories of the structure of cytoplasm: a. A clear liquid supposed to constitute the ground-substance of a cell nucleus and to contain a fibrillar network. b. A liquid supposed to exist in the form of ‘alveolar spheres’ in a continuous, usu. more viscous liquid.
1886Science VIII. 125/1 This basal substance, enchylema, is probably more or less nearly fluid during life. 1888Rolleston & Jackson Forms Anim. Life p. xxi, Protoplasm..appears sometimes to be structureless, but as a rule it is more or less vesicular, consisting of a denser substance (mitome) enclosing droplets of a more fluid character (enchylema, paramitome). 1896E. B. Wilson Cell i. 17 According to the view most widely held, one of its [sc. protoplasm's] essential features is the presence of two constituents, one of which, the ground-substance, cytolymph, or enchylema, is more liquid, while the other, the spongioplasm or reticulum, is of a firmer consistency, and forms a sponge-like network. 1940L. H. Hyman Invertebrates I. i. 2 The spumoid or alveolar theory [of protoplasm], developed by Bütschli, and widely accepted, even today, states that protoplasm is composed of spheres, the alveoli, filled with a clear fluid, the hyaloplasm or enchylema, and suspended in a continuous interalveolar substance. |
