AB  - In this study, 8 hearts of adult donkeys of both sexes were examined grossly. In the right ventricle, <I>Musculus papillaris</I> magnus (mp magnus) was observed to have 2-4 processing nipple like processes, which gave rise to <I>Chordae tendineae</I> (CT) that were observed to divide into 7-12 subbranches. <I>Musculi papillares</I> parvi (mmp parvi) were determined to have 2-3 headed nipple-like structures. The total number of CT varied between 7-12. <I>Musculus papillaris</I> subarteriosus (mp subarteriosus) had either no process or 1-3 process (headed nipple). The number of CT arising from this muscle was observed to vary between 8-11 in the left ventricle. The number of CT that originated from <I>Musculus papillaris</I> subatrialis (mp subatrialis) and <I>Musculus papillaris</I> subauricularis were determined to be 4-12 and 6-14, respectively. All of the CT divided, in turn, into subbranches before attaching to the apex, body and base of the cusps. <I>Trabecula septomarginalis</I> (TS) were observed to exist in both the right and left ventricles in all of the examined animals.
