Morphologic features of the interdigital sinus of the Tuj sheep [Tuj koyununda sinus interdigitalis'in morfolojik özellikleri]

This research,for the first time,documented the interdigital sinuses and their glandular structures of the fore- and hindfeet of the 10 tuj sheep (s male and s female) at gross and subgross and light microscopic leyels. they were noted in all feet as peculiar tubular inyaginations in-between the proximal and middle interdigital joints. the shape of the interdigital sinus resembles that of the pipe,composing of a narrow and long neck and a blind sac. the yascularization was through the 3rd and 4th palmar and dorsal digital arteries at the forefeet,and the 3rd and 4th plantar digital arteries at the hindfeet. the sinus was encircled with a thick capsule connected to the skin and the neighbor tissues through the connectiye tissue. on transyersal section,there were numerous tenuous hairs clearly seen grossly on the section surface. parenchyma and stroma units were obseryed in the interdigital gland. there were also hair follicles,sebaceous and sweat glands,muscle tissue and lymph follicles in the layer of the connectiye tissue. in this study,the morphological features of the interdigital sinuses and the glands that they contain was the first reported in the tuj sheep. they were actiye in all feet,were supplied by different digital arteries and thus,it was supposed that the glands were yery actiye on secretion.
