Abstract

FINE STRUCTURE OF YOUNG, ADULT TURBATRIX ACETI BY S. HIMMELHOCH 1, M. KISIEL 2, J. LAVIMONIERE 2 and B. M. ZUCKERMAN 2 The fine structure of the body wall, digestive tract and excretory system of Turbatrix aceti is de- scribed. The somatic and esophageal musculature contains fewer contractile elements in T. aceti than that of Panagrellus silusiae or Caenorhabditis briggsae. The significance of this observation in terms of movement and internal body pressure is discussed. A description is given of lipid distribution and mitochondria with unusual cristal configurations. The rationale for using micrometozoan models to seek answers concerning the aging processes in man is that basic mechanisms involved in aging are possibly the same in all animals. Excluding life span, one must also consider the possibility that degradative changes with age in small invertebrates are in some ways related to their distinctive structural and functional fabrices, and aging of these features is in no way applicable to man. Indeed, the fact that some organisms have adapted to environmental stresses which cannot be tolerated even by closely related species requires the consideration of alternate paths of senescence between species.
