In a previous study of myofibril size in ‘Pale’ (fast-twitch-glycolytic) fibers of rabbit extraocular muscle (EOM), it was found that individual long Pale fibers demonstrate a substantial increase in the size of myofibril profiles from their prox

It is generally assumed that a muscle fiber is structurally uniform along its length. That assumption is not consistent with the observed variation of myofibrillar profile size along the length of both singly innervated fibers (SIFs) and multiply inn

Arrays of glycogen layers alternating with the double membranes of flattened cisternae were observed in apparently normal muscle. The cisternae of such arrays appeared in both nondistended and evenly distended forms. The distended cisternae retained

Characteristic modes of secondary reorganization were observed in membrane-glycogen complexes of rabbit extraocular muscle. These included (a) an irregular widening or narrowing of the intracisternal space, (b) a loss of the typical intracisternal fl

Mouse superior rectus extraocular muscle was examined in serial section by light and electron microscopy. By such analysis, it was possible to discriminate single versus multiple innervation, characteristics of internal cell morphology, and topograph

SUMMARY The internal fine structure of extraocular muscle cells was observed with scanning electron microscopy. One micrometre Epon sections were etched with an iodine acetone solution. When adhered to carbon coated glass, such specimens may be viewe

Abnormalities of the muscle fiber in the sub-junctional region were observed in association with both normal and disrupted terminal axons. The most frequently observed myopathic change was the presence of extensive areas of densely packed vacuoles be

The electromyogram (EMG) recorded with surface electrodes was examined using a triggered oscilloscope technique. When all but the high-amplitude waveforms in a given segment of activity were excluded from analysis, it was found that the duration of t

Analysis of 432 electron micrographs of membrane-glycogen complexes revealed that: (1) Golgi apparatus is closely associated with 4.2% of the complexes, such associations occurring irrespective of the degree of glycogen loading in the complex. (2) Ap

Intermitochondrial junctions with a spacing of 17-21 nm were observed in the superior rectus muscle of a rat. Periodic rounded densities are aligned midway between the apposed outer mitochondrial membranes at some of these junctions. Such densities h
