Situs

from Wikipedia, the free encyclopedia

Situs (from the Latin situs "position") is a medical term with different meanings depending on the context.

anatomy

Normal situs of the human abdominal organs in an anatomical drawing

In topographical anatomy, a situs is usually the relationship between the internal organs .

The usual position of the internal organs is called the situs solitus .

In contrast to the normal situation, the situs inversus totalis , or situs inversus for short , denotes a mirror-inverted position of all internal organs, which normally does not have any adverse effects on health.

In a situs inversus partialis ( heterotaxy ), only part of the internal organs are shifted to the opposite side. Since there are many possibilities for such a right-left exchange, it is a characteristic of various diseases.

A situs inversus ambiguus , situs ambiguus for short , is used on the one hand when components of the situs solitus and the situs inversus can be found in a person . This definition corresponds to that of the situs inversus partialis.

On the other hand, by a situs inversus ambiguus speaking, if normally the side ( laterally ) lying organs are displaced toward the center of the body. Here, too, various clinical pictures occur.
