ABSTRACT

Background: The extra ocular muscles are supplied by oculomotor, trochlear and abdicants nerves. Aim of our work: Is to study the pattern of motor innervations of the extra ocular muscles in goat. Material and Methods: This study was carried on nerves supplying the oblique and rectus muscles extra ocular muscles of goat. 13 orbits were obtained from 4 goat’s right after killing. The distribution of fiber sizes and the sensory pathway in the stem of oculomotor nerves, oculomotor, trochlear and abdicants were investigated. The technique of silver block impregnation was employed to research muscle innervations. Toludine blue was used to block and stain semi thin slices of the nerves Oculomotor, Trochlear and Abdicant as well as muscle specimens. Results: The nerve supply of extra ocular muscle is relatively rich. The global zone of the muscles was supplied by thin nerve fibers. Different types of pro prospective organs found in extra ocular muscles. Conclusion: The intricate design and operation of the extra ocular muscles control eye movements.
