MESOGASTER Meaning and
Definition
-
Mesogaster is a term commonly used in zoology and anatomy to refer to a specific region of the body in arthropods and insects. The term is derived from the combination of the Greek words "meso," meaning middle or intermediate, and "gaster," which translates to belly or abdomen.
In insects, the mesogaster is the middle section of the body between the thorax and the hindgut. It is typically divided into several segments, each with its own set of specialized structures and organs. The mesogaster houses vital organs such as the digestive system, including the midgut, which is responsible for the digestion and absorption of nutrients. It also contains the circulatory system, including the dorsal vessel or heart, which pumps hemolymph, the insect equivalent of blood, throughout the body. Moreover, it is in the mesogaster where other important structures, such as Malpighian tubules (excretory organs), fat body (storage of nutrients and metabolic functions), and reproductive organs, are often found.
The term "mesogaster" is also applied in the field of zoology to describe similar regions in other arthropods, like spiders, scorpions, and crustaceans. While the specific anatomical details may differ among species, the mesogaster generally refers to the middle section of the body that houses structures critical to vital functions.
Overall, the term mesogaster serves as a useful anatomical reference point for understanding the middle abdominal region and its associated structures in various arthropods.

Etymology of MESOGASTER
The term Mesogaster originates from the combination of two Greek roots: meso meaning middle or within, and gaster meaning stomach or belly. In Greek, gaster is derived from the Proto-Indo-European root ghas-, which refers to the stomach or belly. Therefore, Mesogaster can be interpreted as middle stomach or midsection of the abdomen.
