ENTOSTERNITE Meaning and
Definition
-
Entosternite is a term primarily used in zoology and anatomy to refer to a cartilaginous or bony structure found in the ventral midline of certain arthropods and related organisms. More specifically, it denotes an internal skeletal element located in the lower region of the body, often serving as a site of attachment for various muscles. This structure is considered to be a specialized form of sternite, which is a ventral plate or segment on an arthropod's exoskeleton.
The entosternite can manifest in different forms across various arthropod groups. In crustaceans, it is typically a robust calcified structure located between the mouthparts and connecting the appendages of the head region. In insects, it can be a hardened and elongated plate-like structure present in the thoracic or abdominal region, supporting the flight muscles. Entosternites can also be found in certain spiders and related arachnids, functioning as a support for the muscles involved in movement and predation.
Overall, the entosternite plays a crucial role in providing support and stability to the body, while acting as an anchor for muscle attachment. Its presence and characteristics can vary significantly across different arthropod species, contributing to the vast diversity observed within this group of organisms.

Etymology of ENTOSTERNITE
The word "entosternite" is derived from two root words: "ento-" and "sternite".
1. "Ento-" comes from the Greek word "entos", meaning "within" or "inside". This root is commonly used in scientific and medical terminology to indicate something internal or located inside something else.
2. "Sternite" is derived from the Latin word "sternum", which refers to the breastbone or the ventral (underside) part of the thorax in animals.
Combining these root words, "entosternite" refers to a structure that is internal or within the sternite, usually found in arthropods. In arthropod anatomy, the sternite refers to the ventral plate or segment of the exoskeleton. An entosternite, therefore, is a structure located inside the sternite.
