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...
متن کاملOutcome of index finger pollicisation for the congenital absent or severely hypoplastic thumb.
Pollicisation of the index finger for absence or severe hypoplasia of the thumb has been reported as a good procedure to recreate a new "thumb" with good cosmesis and acceptable function. The purpose of this study is to evaluate the outcome of our series. Seventeen patients with 24 involved hands agreed to come back for evaluation. The mean age at operation was 12 months. In 8 hands there was a...
متن کاملTraumatic avulsion of extraocular muscles: case reports.
We described the clinical, surgical details and results (motor and sensory) of the retrieving procedure of traumatically avulsed muscles in three patients with no previous history of strabismus or diplopia seen in the Department of Ophthalmology, State University of Campinas, Brazil. The slipped muscle portion was reinserted at the original insertion and under the remaining stump, which was sut...
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 کاملIntermediate filaments in the human extraocular muscles.
PURPOSE To investigate the distribution of the intermediate filament (IF) proteins desmin, vimentin, and nestin in human extraocular muscles (EOMs). METHODS Healthy adult EOM samples were serially sectioned (5 and 1 μm) and processed for immunohistochemistry, with specific antibodies (Abs) against desmin, vimentin, and nestin and different myosin heavy chains (MyHCs), including the newly char...
