The cyclopædia of anatomy and physiology cyclopdiaofana0402todd Year: 1849 Cliild with ectopia viscentm. a, liver ; b, heart; r, c, lung ; d, stomach ; e, spleen ; /,/, intestinal canal; </, kidney ; h, chorion ; i, am nion ; k, umbilical cord ; m, placenta. The skeleton is very imperfect, in this com- plete ectopia ; the thorax open, and the ver- tebral column misformed by scoliosis.— This may produce, as often met with in calves, a complete inversion of the bodv, so that through distortion of the spine, the head is placed between the hind feet. This is what liurlt calls schistozomus , and what I represent in Jig. 601. Fig. 601. Schistozomus reflexus (Gnrlt). 2. Fissure of the Thorax. Eclopia of the heart. — In the regular evo- lution of the foetus, the opening on the anterior wall of the body closes itself, first at its superior part, so as to cover the thoracic viscera, while a part of the abdominal intes- tines still remain out of their cavity and in the sheath of the umbilical cord. Thus the thoracic cavity is in general already closed, whilst the abdominal is yet open. Neverthe- less, it sometimes happens that the abdominal cavity is completed, and that its viscera are perfectly enclosed, whilst the thorax remains open, and the heart is placed on its anterior surface. In this malformation, called ectopia cordis, the heart has no pericardium, and is situated on the median line of the anterior wall of the thorax ; it is more or less rounded, and in general well formed, as may be seen in fill. 595. The sternum is wanting (Tournelle, Norand, Sandifort); divided into two parts (Buttner, Martinez) ; or formed only by the manubriiim (Manchardt). It is rarely com- plete ; but this is often the case when the heart protrudes at the neck (Muse, Bubon- nais, Breschet), or in the epigastric region (Wilson). During fcetal life, the ectopia of the heart is immaterial, but soon after birth i
