Özet
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 is compactly organized while the inner one is observed as spongy in appearance with large trabeculae oriented between branched bundles of cardiac muscle. The pyramidal shape and myoarchitectural features of the ventricle was evaluated and discussed as being the most important histological parameter of metabolic activity which is depended on myocardial functions.
