    The superior (dorsal), lateral and medial rectus muscles from 5 adult humans and Kıvırcık sheeps were included in the study. Transversal sections of 5 micrometers in thickness from the venteria (middles) of the muscles embedded in paraffin were prepared by rutin method and examined under stereomicroscope at 4x2x10 magnification. The primary, secondary and tertiary fibre bundles from all of the muscles except the medial rectus muscle of human were obviously observed in the sections. The biggest and the smallest muscle fibres were determined in the lateral rectus muscle of sheep and the superior rectus muscle of humans respectively. The muscle fibres in primary bundles were found to be much intensive in sheep eye muscles compared with those of humans. Consequently, despite to less number of fibres in muscle bundles, connective tissue between the bundles was seen much more abundantly in humans who have more eye movements compared with those of sheep
