Barnacle Muscle Fibers
Constant current pulses have been applied to single muscle fibers of the barnacle, Balanus nubilus Darwin, with an axial metal electrode. The membrane potential change, which took place over a large part of the muscle fiber, was measured with a similar electrode. Depolarizing pulses, if the voltage was greater than threshold, produced tension. The size of the tension was a function of the magni...
متن کاملTypes of Muscle Fibers
How skeletal muscles adapt to a repeated stimulus depends, to a large extent, on the inherent char ac ter is tics of the muscles themselves. Spe cifi cal ly, the types of fi bers that make up individual muscles greatly in fl u ence the way your athletes will adapt to their training programs. There is a reason why some athletes can sprint faster and get bigger muscles more easily than others, an...
متن کاملStability of diacylglycerol acyltransferase in dehydrated bovine muscle tissue.
Meaningful estimates of diacylglycerol acyltransferase (EC 2.3.1.20) activity in different tissue samples require effective, unbiased methods of sample storage. Samples of the pars costalis diaphragmatis muscle (skirt muscle of the diaphragm) were obtained from 18- to 20-month-old cattle and assayed for microsomal protein content and diacylglycerol acyltransferase activity after having been sto...
متن کاملCentrioles in Intrafusal Muscle Fibers
Centrioles are generally considered to be involved in cell division and are also related to the differentiation of cilia and flagella . Most skeletal muscle contains stretch receptors called muscle spindles consisting of a bundle of small (intrafusal) muscle fibers which are innervated by both sensory and motor nerves . The fine structure of muscle spindles in a variety of species from amphibia...
متن کاملAging of Skeletal Muscle Fibers
Aging has become an important topic for scientific research because life expectancy and the number of men and women in older age groups have increased dramatically in the last century. This is true in most countries of the world including the Republic of Korea and the United States. From a rehabilitation perspective, the most important associated issue is a progressive decline in functional cap...
