Resumen: PURPOSE. To analyze in a frontal-eyed mammal (cat) the postnatal development of palisade endings in extraocular muscles (EOMs) and to compare the spatiotemporal and quantitative patterns of palisade endings among individual rectus muscles. METHODS. Cats of different ages ranging from birth to adult stage were studied. EOM wholemount preparations were fluorescently labeled using six combinations of triple staining and analyzed in the confocal laser scanning microscope. RESULTS. Palisade endings developed postnatally and passed in each rectus muscle through the same, three developmental steps but in a heterochronic sequence and to a different final density per muscle. Specifically, palisade ending development was first completed in the medial rectus and later in the inferior, lateral, and superior rectus. The highest density of palisade endings was observed in the medial rectus and the lowest in the lateral rectus whereas values for the inferior and superior rectus were in be...
