Postnatal changes in the developing rat extraocular muscles.

PURPOSE To examine the distribution and timing of expression of nonmuscle myosin IIB (nmMyH IIB) and the extraocular muscle (EOM)-specific myosin (EO-MyHC) during postnatal development of the rat extraocular muscles. METHODS Whole orbits were collected from postnatal development day (P) 1 through P30 from Sprague-Dawley rats. Samples were analyzed by immunofluorescence microscopy and Western ...

Histochemistry of primate extraocular muscles and the changes of denervation.

The morphological and physiological classification of the fibres of the extraocular muscles has been the subject of some controversy, not to say confusion. It is well known that in mammals the oblique and rectus muscles consist of a peripheral layer of smaller fibres overlying a deeper zone with larger diameters (Kato, I938; Kern, I965). Many morphological and ultrastructural studies have descr...

Ultrastructural changes in rabbit extraocular muscles after oculomotor nerve section.

Ultrastructural changes in rabbit superior recti have been studied from 24 hours to 21 days after intracranial section of the oculomotor nerve. Earliest changes were observed in a few myelinated axons within the muscle 24 hours after nerve section. Within 48 hours, degenerative changes in the myelinated axons became manifest and fragmentation of the myelin sheaths started. During the second and...

Postnatal lung function in the developing rat.

Little is known about lung function during early stages of postnatal maturation, although the complex structural changes associated with developing rat lung are well studied. We therefore analyzed corresponding functional (lung volume, respiratory mechanics, intrapulmonary gas mixing, and gas exchange) and structural (alveolar surface area, mean linear intercept length, and alveolar septal thic...

Neurophysiology of extraocular muscles.

E. lye movements may be divided grossly into "tonic" and "phasic" movements. Are both of these principal types produced by the same motor nerves and muscle fibers, or are separate systems present that are functionally suited to each of the types of movements? Morphological and physiological studies demonstrate that at least two and possibly three neuromuscular systems are present in eye muscles...
