The Sarcoplasmic Reticulum: Storage and Release of Calcium,cle, but Sandow (1965) calculated that the amount of calcium entering the stimulated muscle cell is too small and its diffusion into the interior of the fibre too slow (cf. also Hill 1948) to account for the rapid onset of contraction. In these fast and wide-fibred muscles the activator calcium is r

The Dependence of Muscle Contraction and Relaxation on the Intracellular Concentration of Free Calc can be determined more precisely and conveniently. In the following sections we shall see that the quantitative relationship between intracellular Ca. concentration and contraction is similar in different kinds of invertebrate muscle (Sect. 3.1) and vertebrate muscle (Sect. 3.2), whereas the tempor

Myosin-Linked Regulation of Molluscan Muscle, the actin-activated myosin ATPase is repressed by an inhibitor, the so-called regulatory light chain of molluscan myosin (Sect. 6.1). A different regulatory mechanism is found in the slow adductor smooth muscle of bivalves showing the “catch phenomenon” (Sect. 6.2). Because of the ease with which t

Principles of Calcium Signalling in Muscle, transfer are, however, quite different in various types of muscle. In fast skeletal muscle, for instance, an electric signal, the action potential, travels along the membrane invaginations, the transverse tubules, and hits the triads where this extracellular message is transformed into an intracell
