In hydras and other two-layered animals, one kind ofcellserves as both muscle and epithelial cells. The compact body of each cell is packed closely with theadjacentcells to form anepithelium, and the base of each cell, where it meets the mesoglea, is drawn out into a long muscle fibre...
Muscles consist of long slender cells (fibres), each of which is abundleof finer fibrils (Figure 1). Within each fibril are relatively thick filaments of theproteinmyosin and thin ones ofactinand other proteins. When a muscle fibre lengthens or shortens, the filaments remain essentially constant...
HENRY HUDDART, in The Comparative Structure and Function of Muscle, 1975 Membrane Circuitry Before we can proceed to consider the propagation of the action potential down the muscle fibre membrane, it is necessary to examine the electrical properties of the membrane and just how these may be alte...

Lotmar and Picken proposed a mono-clinic unit of structure, with a= 11.70 A., b= 5.65 A., c= 9.85 A., β = 73.5°, and they suggested that the crystalline substance, assumed to be protein, contains nearly extended polypeptide chains, parallel to the β-axis (the fibre axis), with...

The duration of muscle fibre contraction is not uniform within whole muscles. In fact all muscles are made up of a variety of types of fibre. Some muscle fibres take only 80 ms to attain their maximum tension, whereas others take more than twice this time. Different types of muscle fibres...
the muscle fibre composition protein network via the heat shock response, thus forming a protein–protein interaction network of muscle metabolism and structure. The maintenance and completion of muscle fibre growth and development often require the participation of a variety of proteins in the form ...
