| Summary: | The aim of this study is to reveal the macroanatomy of the
heart valves of the 5 white pelicans. The left atrioventricular
valve consists of one septal and two parietal leaves (cuspis).
The left atroventricular valve having a muscular structure
was attached to the parietal face of the atrioventricular orifice
and its free edge, flapped into the right ventricle, was
fixed to the septum by a short left septal attachment, and
gave attachment to rough parietal wall of the ventricle by
a thick muscular stalk. The rectangle shaped valves of the
right atrioventricular ventricle had chordae tendineae-likestructures
near the septal edge of the valve and external
wall, whose free edges were linked to the ventricle wall by
chordae tendineae. The aortic orifice is encircled by the aortic
valve, composed of three semilunar cusps; right, left and
septal. The pulmonary valve consists of three cusps. In all
examined materials, the semilunar cusps in the central part
of the free margin of each cusp had the semilunar valve nodules.
The minor anatomic changes observed in this work
may be resulted from differences of species. |
