The slipped muscle portion was reinserted at the original insertion and under the remaining stump, which was sut...

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...
متن کاملHistology and Physiology of the Extraocular Muscles
As described in Chapter 4, the extraocular muscles perform two functions: optostatic and optokinetic. The optostatic function requires that the muscles maintain a state of postural tonicity; the optokinetic function requires that quick, tetanic contractions be performed. These two contradictory functions are served by two different sets of muscles in the skeletal muscle system. Eye muscles, how...
متن کاملThe nonlinearity of passive extraocular muscles.
Passive extraocular muscles (EOMs), like most biological tissues, are hyperelastic, that is, their stiffness increases as they are stretched. It has always been assumed, and in a few occasions argued, that this is their only nonlinearity and that it can be ignored in central gaze. However, using novel measurement techniques in anesthetized paralyzed monkeys, we have recently demonstrated that E...
