The ventricle was pyramidal in shape, and itswall was comprised of epicardium, myocardium, and endocardium. Epicardium andendocardium were thin and had similar histological structure that consisted ofsimple squamous epithelium and connective tissue. The thicker layer,myocardium, was composed of two layers differentiated easily: the outer part iscompactly organized while the inner one is observed as spongy in appearancewith large trabeculae oriented between branched bundles of cardiac muscle. Thepyramidal shape and myoarchitectural features of the ventricle was evaluatedand discussed as being the most important histological parameter of metabolicactivity which is depended on myocardial functions.

Ventrikül, piramit biçimlidir ve ventrikül duvarı epikardiyum,miyokardiyum ve endokardiyum tabakalarından meydana gelmiştir. Epikardiyum veendokardiyum tek katlı yassı epitel ile ince bir bağ dokudan oluşmuştur. Dahakalın bir tabaka olan miyokardiyum, kolayca ayırt edilebilen iki tabaka halindeizlenmiştir; dış tabaka, sıkı şekilde organize olmuşken iç tabaka, dallanmışkalp kası demetleri arasında yer alan iri trabekülleri ile süngerimsi görünümesahiptir. Ventrikülün piramidal biçimi ve kas düzenlenişi metabolik aktiviteninönemli bir parametresi olarak değerlendirilerek tartışılmıştır. CR - Burggren, W.W., Farrell, A.P. & Lillywhite, H. (1997).
