Özet
Bu çalışmada zebra çiklit (Amatitlania nigrofasciata) ventrikülünün morfolojik ve histolojik özellikleri ışık mikroskobu ile incelenmiştir. Ventrikül, piramit biçimlidir ve ventrikül duvarı epikardiyum, miyokardiyum ve endokardiyum tabakalarından meydana gelmiştir. Epikardiyum ve endokardiyum tek katlı yassı epitel ile ince bir bağ dokudan oluşmuştur. Daha kalın bir tabaka olan miyokardiyum, kolayca ayırt edilebilen iki tabaka halinde izlenmiştir; dış tabaka, sıkı şekilde organize olmuşken iç tabaka, dallanmış kalp kası demetleri arasında yer alan iri trabekülleri ile süngerimsi görünüme sahiptir. Ventrikülün piramidal biçimi ve kas düzenlenişi metabolik aktivitenin önemli bir parametresi olarak değerlendirilerek tartışılmıştır.
The morphological and histological structures of the ventricle of convict cichlid (Amatitlania nigrofasciata) were described light microscopically. The ventricle was pyramidal in shape, and its wall was comprised of epicardium, myocardium, and endocardium. Epicardium and endocardium were thin and had similar histological structure that consisted of simple squamous epithelium and connective tissue. The thicker layer, myocardium, was composed of two layers differentiated easily: the outer part was compactly organized while the inner one was observed as spongy in appearance with large trabeculae oriented between branched bundles of cardiac muscle. The pyramidal shape and myoarchitectural features of the ventricle were evaluated and discussed as being the most important histological parameter of metabolic activity which is depended on myocardial functions.
