PELAGIC FISHES | An Introduction to the Biology of Pelagic Fishes D. Bernal, in Encyclopedia of Fish Physiology, 2011 Fast-twitch muscle fiber type of large diameter with a high anaerobic capacity, large fiber size, low mitochondrial density, and myoglobin concentration; powers short-duration, high...
Muscle Fiber Synonyms Muscle cell;Myofiber Definition Muscle fibers are the smallest cellular elements of the contractile machinery in mammalian skeletal muscles (Fig.1). During their ontogeny, muscle fibers form by end-to-end fusion of mononucleated postmitotic myoblasts into multinucleated myotubes, ...
Paul Davidovits, in Physics in Biology and Medicine (Fifth Edition), 2019 13.1.8 Action Potentials in Muscles Muscle fibers produce and propagate electrical impulses in much the same way as neurons. The action potential in the muscle fiber is initiated by the impulses arriving from motor neurons...
Equations are derived describing potentials due to an active muscle fiber in an infinite medium in terms of two surface integrals—one of the propagated action potential and the other of the membrane current density, both integrals being taken over the surface of the muscle. These equations are ...
The Across-Fiber Pattern Theory: An Organizing Principle for Molar Neural Function This chapter discusses the across-fiber pattern theory of sensory neural coding for the neural representation of the qualitative difference between various tastes stimuli. The distinction between various tastes stimuli is ba...
2d). Most strikingly, interactions between promoters and active enhancers were rewired in a lineage- and differentiation-dependent manner, and iPax7-specific P–En interactions were observed at genes with functional relevance for skeletal muscle biology (Fig. 2d, Supplementary Fig. 3E, F, and ...
As two sEMG signals detected at different points along a fiber are usually not identical, there is no strict mathematical definition of the delay between them. Thus, several methods for CV estimation from sEMG recordings have been proposed (for a review, see Farina and Merletti (2004b)). The...
Steady-state free precession is the sequence of choice for cine imaging because of its clear definition ofendocardialand epicardial borders. 2.1.2T2-Weighted Imaging T2-weighted (T2W) short-tau inversion recovery (STIR) imaging is a sequence sensitive to increased myocardial water content and thus...
Transitions of muscle fiber phenotypic profiles Skeletal muscle is a complex, versatile tissue composed of a large variety of functionally diverse fiber types. The overall properties of a muscle largely ... D Pette,RS Staron - 《Histochemistry & Cell Biology》 被引量: 753发表: 2001年 New insigh...
