Abstract

Bu çalışmada bıldırcında (Coturnix coturnix japonica) pecten oculi, morfolojik olarak incelendi. Ortalama 19 adet kıvrıma sahip olan pecten oculi’nin, retina’ya tutunduğu tespit edildi. Bıldırcında pecten oculi’nin deniz kabuğu biçimli, yamuk benzeri bir şekle sahip olduğu ve bu nedenle kıvrımlı tip pecten grubuna dahil olduğu gözlendi. Ortalama olarak her bir kıvrım kalınlığı 259 µm olup, bu kalınlık kıvrımlar üzerinde her noktada sabit bulundu. Işık mikroskobik olarak, çok sayıda kapillar ve pigment hücreleri (melanositler) içeren pecten oculi’nin tabanı, discus nervi optici’nin ventral’inden retina’ya doğru yayılım göstermekteydi

Morphological investigation of the pecten oculi in quail (Coturnix

Abstract

In this study pecten oculi was investigated morphologically in quail (Coturnix coturnix japonica). It was detected that the pecten oculi was attached to the retina and consisted of 19 folds on average. It was observed that quail pecten was in the pleated group and had a shell like rhomboid shape. The width of the folds was 259 µm on average. The width of the each fold was constant on every region of the fold. In light microscopic investigation, pecten was consisted of large number of capillaries and pigment cells (melanocytes) and the basal edge of pecten lined from the ventral part of the optic disc through the retina ventrally and projected into the vitreous body
