Özet

Bu çalışma, gündüz yırtıcı kuşlardan kızıl şahin (Buteo rufinus) beyninin makroskobik ve ışık mikroskobik özeliklerini belirlemek amacıyla gerçekleştirildi. Araştırmada, Yozgat Doğa Koruma ve Milli Parklar Şube Müdürlüğü ile Afyon Kocatepe Üniversitesi Yaban Hayatı Kurtarma ve Rehabilitasyon Merkezi'ne yaralı olarak getirilen ancak kurtarılamayan 5 adet erişkin kızıl şahin kullanıldı. Kızıl şahinin beyin dokuları makroskobik ve ışık mikroskobik incelemelere tabi tutuldu. Makroskobik olarak armut şeklindeki beynin, kuşlara özgü pürüzsüz bir yüzeye sahip olduğu gözlendi. Bulbus olfactoriuslar, rostroventral bölgede küçülmüş yapıda tanımlandı. Oldukça gelişmiş bir lobus opticus tespit edildi. Cerebellumun büyük ve yanlardan basık olduğu, üzerinde fissura cerebelli ile birbirinden ayrılan 11 ila 13 adet folia cerebelli bulunduğu belirlendi. Işık mikroskobik incelemelerde, cortex cerebrinin dıştan piamater ile sarılı olduğu ve memelilerde görülen tipik laminer organizasyona sahip olmadığı gözlendi. Cerebellumun dışta moleküler katman, ortada Purkinje hücre katmanı ve en içte granüler katman olmak üzere üç tipik tabakadan oluştuğu görüldü. Medulla oblongatada piamater, piramit benzeri hücreler ve glia hücreleri ayırt edilirken, lobus opticusun az sayıda glia hücresi içeren, orta büyüklükte küresel nöronlar ve piramidal hücrelerden oluştuğu gözlendi. Elde edilen bulgular, kızıl şahin beyin yapısına ait kapsamlı nöroanatomik veriler sunmakta ve gündüz yırtıcı kuşların karşılaştırmalı beyin morfolojisi ile histolojisine katkı sağlamaktadır.

Abstract

This study was conducted to determine the macroscopic and light microscopic characteristics of the brain of the long-legged buzzard (Buteo rufinus), a diurnal bird of prey. The study utilized five adult long-legged buzzard that were brought to the Yozgat Directorate of Nature Conservation and National Parks and the Afyon Kocatepe University Wildlife Rescue and Rehabilitation Center as injured but could not be saved. The brain tissues of the long-legged buzzard were subjected to macroscopic and light microscopic examinations. Macroscopically, the pear-shaped brain was observed to have a smooth surface characteristic of birds. The olfactory bulbs were identified as having a reduced structure in the rostroventral region. A highly developed optic lobe was detected. It was determined that the cerebellum was large and laterally flattened, with 11 to 13 cerebellar folia separated by the fissura cerebelli. During light microscopic examination, it was observed that the cerebral cortex is enveloped externally by the pia mater and does not exhibit the typical laminar organization seen in mammals. The cerebellum was found to consist of three typical layers: the molecular layer on the outside, the Purkinje cell layer in the middle, and the granular layer on the inside. In the medulla oblongata, the pia mater, pyramidal cells, and glial cells were distinguished, while the optic lobe was found to consist of medium-sized spherical neurons and pyramidal cells, containing a small number of glial cells. The findings provide comprehensive neuroanatomical data on the brain structure of the long-legged buzzard and contribute to the comparative brain morphology and histology of diurnal birds of prey.
