Macro-anatomical investigation of encephalon in donkey

Abstract

In this macro-anatomical research, the data was based on direct observations of 14 adult donkey brains 10 male and 4 female. The brains were fixed in 10% formalin solution and the investigation was focused on macroscopic descriptions of the brain surface and of dissected brainstem features. Sulci and gyri on the brain hemispheres had quite curly structures. These were not completely symmetrical both among brains of different donkeys and on two hemispheres of same brains. It was determined that an adult donkey brain weight was 370 ± 7 g, brain/body weight ratio was 0.27%; cerebellum/brain weight ratio was 10.54%; and pituitary gland/brain weight ratio was 0.38%

Merkepte encephalon’un makroanatomik olarak incelenmesi

Abstract

Bu makro-anatomik araştırmada 10 erkek, 4 dişi toplam 14 adet yetişkin merkebin beyni kullanıldı. Beyinler %10’luk formalin solusyonu ile tespit edildikten sonra beyin yüzeyi ve diseke edilen beyin kökü makroskobik olarak incelendi. Merkep beyninde sulci ve gyri’nin oldukça kıvrımlı bir yapıya sahip olduğu; hem bireyler arasında, hem de aynı bireyin hemispherium’ları üzerinde tam bir simetri olmadığı görüldü. Merkepte beynin ağırlığı 370 ± 7 g, olarak saptandı. Beyin / Vücut ağırlıkları oranı % 0.27; Cerebellum / beyin ağırlıkları oranı % 10.54; glandula pituitaria / beyin ağırlıkları oranı % 0.38 olarak hesaplandı
