Rhythmic activity in skeletal muscle fibres

Rhythmic activity in smooth muscle

JOHANESON, BORJE, AND DAVID F. BOHR. Rhythmic activity in smooth muscle from small subcutaneous arteries. Am. J. Physiol. 210(4): 801-806. I g66.-Isolated strips of small subcutaneous arteries (200-500 p o.d.) from the dog’s paw show two components in their contractile behavior: I) a tonic increase in tension and 2) superimposed phasic contractions which are often grouped to form rhythmic waves...

Three components of calcium currents in crayfish skeletal muscle fibres.

The coexistence of multiple types of calcium currents within the same cell has been demonstrated in voltage clamp experiments in several cells (for review see Hagiwara et Byerly 1981). Single channel recordings confirmed the existence of distinct electrical and pharmacological properties of Ca channels and, based on these differ­ ences, three types of Ca channels were characterized (classified)...

"Current" advances in mechanically skinned skeletal muscle fibres.

1. In skeletal muscle, excitation-contraction (E-C) coupling describes a cascade of cellular events initiated by an action potential (AP) at the surface membrane that ultimately results in muscle contraction. Being able to specifically manipulate the many processes that constitute E-C coupling, as well as the many factors that modulate these processes, has proven challenging. 2. One of the simp...

A Simplified Immunohistochemical Classification of Skeletal Muscle Fibres in Mouse

The classification of muscle fibres is of particular interest for the study of the skeletal muscle properties in a wide range of scientific fields, especially animal phenotyping. It is therefore important to define a reliable method for classifying fibre types. The aim of this study was to establish a simplified method for the immunohistochemical classification of fibres in mouse. To carry it o...
