The structure of skeletal muscle. (A) An overview of skeletal muscle structure is shown; skeletal muscle features a “cable-within-a-cable” structure, in which individual muscle fibers are aligned in parallel with the length of the tissue and are ensheathed by extracellular matrix proteins. (...
The terminal arterioles perfuse the capillaries located in the endomysium; this part of the skeletal muscle structure is termed the microvascular unit. Embryology Somites are segmental axial structures of mesoderm. The ventral part of a somite is termed the sclerotome, contributing to the ...
The objective of this review is to provide a systems-level, comprehensive mapping the molecular mechanisms underlying skeletal muscle structure and function, in health and disease. We begin this review with a focus on molecular mechanisms underlying muscle tissue development (myogenesis), with an ...
This chapter investigates the structure and organization of skeletal muscle at an intermediate level, serving as a bridge between Chaps. 1 and 2. Hence, learn about the hierarchical matrix of skeletal muscle design or individual parts leading to a better appreciation of the composite structure of...
Decades of research in skeletal muscle physiology have provided multiscale insights into the structural and functional complexity of this important anatomical tissue, designed to accomplish the task of generating contraction, force and movement. Skeletal muscle can be viewed as a biomechanical device with...
Here we isolated the native DGC from mouse skeletal muscle and obtained its high-resolution structure. Our findings unveil a markedly divergent structure from the previous model of DGC assembly. Specifically, on the extracellular side, β-, γ- and δ-sarcoglycans co-fold to form a specialized,...
Nucleus, in biology, a specialized structure occurring in most cells (except bacteria and blue-green algae) and separated from the rest of the cell by a double layer, the nuclear membrane. The nucleus controls and regulates the activities of the cell (e.
Prolonged periods of skeletal muscle inactivity lead to a loss of muscle protein and strength. Advances in cell biology have progressed our understanding o... SK Powers,AN Kavazis,KC Deruisseau - 《Am J Physiol Regul Integr Comp Physiol》 被引量: 1556发表: 2005年 Protein and amino acid meta...
Muscles perform a wide range of motile functions in animals. Among various types are skeletal and cardiac muscles, which exhibit a steady auto-oscillation of force and length when they are activated at an intermediate level of contraction. This phenomenon, termed spontaneous oscillatory contraction or...
it is the neural system that controls the voluntary actions in the body by transmitting impulses from cns to skeletal muscle cells. it consists of the somatic nerves. autonomic neural system (ans): the autonomic neural system is involved in involuntary actions like regulation of physiological ...
