However, anatomical studies in the late 19th and the early 20th century using gold and silver staining of diverse muscles from different species suggested the presence of unmyelinated, thin nerve fibers and their extension into netlike structures in the immediate vicinity of NMJs (Bremer 1882; ...
Skeletal muscles account for ~30-40% of the total weight of human body and are responsible for its most important functions, including movement, respiration, thermogenesis, and glucose and protein metabolism. Skeletal muscle damage negatively impacts the whole-body functioning, leading to deterioration ...
Describe the criteria used to name skeletal muscles Explain how understanding the muscle names helps describe shapes, location, and actions of various muscles The Greeks and Romans conducted the first studies done on the human body in Western culture. The educated class of subsequent societies studied...
However, the actions of SUMO in skeletal muscle pathophysiology are still not investigated. In this study, we quantified the abundance of the SUMO enzymes and determined the distribution of SUMOylated proteins along the fibers of nine different muscles. We find that skeletal muscles contain a ...
Skeletal muscleis a highly specialized tissue. Its primary function is to generate longitudinal contraction. Skeletal muscles are unique tissues that are composed of bundles of highly oriented and dense muscle fibers, each a multinucleated cell derived from myoblasts. The muscle fibers in native skele...

both PGC-1α mRNA and protein levels are reduced in aged muscles.172,173,174,175More recently, changes in mitochondrial function are recognized as a contributing factor in muscle performance in sarcopenia. For instance, maximal mitochondrial ATP production (ATPmax), as determined by measurements of...
