Stereological Analysis of Mammalian Skeletal Muscle
A quantitative analysis of the volumes, surface areas, and dimensions of the ultrastructural components in the soleus muscle fibers of the guinea pig was made by using point counting methods of stereology. Muscle fibers have structural orientation (anisotropy) and have spatial gradients of the structures within the fiber; therefore the standard stereological methods were modified where necessar...
متن کاملMicrosomal T system: a stereological analysis of purified microsomes derived from normal and dystrophic skeletal muscle
Heterogeneous populations of microsomes obtained from normal and dystrophic chicken pectoralis muscle were separated into two subfractions by an iterative loading technique. The buoyant density of the sarcoplasmic reticulum (SR) microsomes was increased after loading them with calcium oxalate. Several incubations in the transport medium were necessary to load all of the SR. The fraction that di...
متن کاملThe Dynamic Properties of Mammalian Skeletal Muscle
The dynamic characteristics of the rat gracilis anticus muscle at 17.5 degrees C have been determined by isotonic and isometric loading. For a fixed initial length these characteristics were represented either as a family of length-velocity phase trajectories at various isotonic afterloads or as a series of force-velocity curves at different lengths. An alternate method of viewing these data, t...
متن کاملThe Active State of Mammalian Skeletal Muscle
A new technique is proposed for computing the active state of striated muscle, based on the three component model of Fenn and Marsh (8) and of Hill (7). The method permits calculation of the time course of the active state from its peak to the time at which maximum isometric twitch tension is reached. The intormation required for the calculation can be obtained from a single muscle without movi...
متن کاملCarnosine and Anserine in Mammalian Skeletal Muscle *
Two imidazole derivatives, carnosine and anserine, have been isolated from vertebrate skeletal muscle. Carnosine may be readily obtained from the ox (l), horse (2), pig (3), etc. Anserine, a methyl carnosine, has been isolated from birds, a reptile (4), fish (5), and certain mammals (6). The presence of the two compounds in muscles from the same animal has been adequately demonstrated only once...
