Evidence for active control of rectus extraocular muscle pulleys.
PURPOSE Connective tissue structures constrain paths of the rectus extraocular muscles (EOMs), acting as pulleys and serving as functional EOM origins. This study was conducted to investigate the relationship of orbital and global EOM layers to pulleys and kinematic implications of this anatomy. METHODS High-resolution magnetic resonance imaging (MRI) was used to define the anterior paths of ...
متن کاملEvidence for rectus extraocular muscle pulleys in rodents.
PURPOSE Extraocular rectus muscle (EOM) pulleys are important determinants of orbital biomechanics in humans. In this study, the authors evaluated orbital connective tissue morphology, specifically characterizing rectus muscle pulleys, in the rat, a species with laterally placed eyes, afoveate vision, and a less complex visuomotor repertoire than primates. METHODS Adult rat orbits were paraff...
متن کاملExtraocular motor unit and whole-muscle responses in the lateral rectus muscle of the squirrel monkey.
Because primate studies provide data for the current experimental models of the human oculomotor system, we investigated the relationship of lateral rectus muscle motoneuron firing to muscle unit contractile characteristics in the squirrel monkey. Also examined was the correlation of whole-muscle contractile force with the degree of evoked eye displacement. A force transducer was used to record...
متن کاملQuantitative analysis of rectus extraocular muscle layers in monkey and humans.
PURPOSE Rectus extraocular muscles (EOMs) consist of orbital (OL) and global (GL) layers. This study enumerated the fibers in both layers along the length of each EOM. METHODS Four human (ages 17 months-93 years) and three monkey (ages 5-7 years) orbits were serially sectioned in the coronal plane and stained with Masson's trichrome. All fibers of the rectus EOMs were counted using light micr...
متن کاملStructure-function correlations in the human medial rectus extraocular muscle pulleys.
PURPOSE Fibroelastic pulleys function like the trochlea to fix the position and pulling direction of the recti extraocular muscles within the orbit. This study characterized the fine structure of the human medial rectus muscle pulley. METHODS Human medial rectus muscle pulley tissue was dissected at autopsy, immersed in aldehyde fixative solution, and processed for and examined with light and...
