The Biology of Stentor


Book Description

The Biology of Stentor summarizes all that has been learned about the biology of a certain group of ciliate protozoa: the stentors. Topics covered range from form and function in Stentor to behavior, fine structure, growth and division, and reorganization. Regeneration is also discussed, along with polarity, metabolism, genetics, and primordium development. This volume is comprised of 20 chapters and begins with a characterization of Stentor, with emphasis on its particular advantages in addressing general problems of biology. The reader is then introduced to form and function in Stentor, particularly S. coeruleus. The following chapters focus on the behavior (food selection, swimming, response to light, etc.) of stentors and the fine points of structure in terms of which this behavior is to be explained and which demonstrate the highly complex and precise achievements of morphogenesis. The remaining chapters explore growth and division in Stentor as well as the course of reorganization and regeneration; development of the oral primordium and how it is activated and inhibited; rate of regeneration in relation to the polar axis; fusion masses of whole stentors; and reconstitution in disarranged stentors. Various species of Stentor are also described, together with the techniques used to study them. The final chapter deals with hypotheses concerning the morphogenesis of ciliates. This book will be of interest to students and practitioners of biology and physiology.

Principles of Regeneration


Book Description

Principles of Regeneration focuses on the principles, methodologies, and changes involved in the process of regeneration. The book first underscores the nature of the nucleus in Acetabularia, enzyme effects, role of ribonucleic acid in morphogenesis, and functions of the stentor. The text then takes a look at the turnover in hydroids and flatworms and regeneration blastema. Discussions focus on regeneration in hydra, interstitial cells, colonial hydroids, neoblasts, and morphogenetic fields. The publication surveys segmental addition in annelids and molting, metamorphosis, and regeneration in arthropods. The termination of regeneration, importance of nerves, morphogenesis, histogenesis of the regenerate, and role of the nerves are discussed. The manuscript also examines regeneration in fishes, amphibian limb, horns and antlers, and heads and tails. The manuscript is a dependable source of data for students of developmental biology, anatomy, and evolution, as well as teachers and researchers in biology and medicine.
