MESOCOELIA Meaning and
Definition
-
Mesocoelia is a term used in biology and paleontology to describe a specific anatomical feature found in certain organisms. It refers to the cavity or space that exists between the inner and outer layers of the body, often within a coelomate organism.
In coelomate animals, the body cavity is typically divided into different sections or compartments. The mesocoelia specifically refers to the middle portion or compartment within this body cavity. It is situated between the mesodermally derived lining of the outer body wall (somatic mesoderm) and the lining of the internal organs (visceral mesoderm).
The presence of a mesocoelia is important for the organization and functioning of the internal systems within an organism. It allows for the separation and protection of the organs from the outer body wall, while also providing a space for specific biological processes to occur. For example, in some animals, the mesocoelia may house important circulatory or reproductive structures.
The term "mesocoelia" is commonly used in the context of describing the internal anatomy of various animals, such as annelids, arthropods, and certain mollusks. Understanding the structure and function of the mesocoelia aids in the study and classification of these organisms and contributes to our overall knowledge of animal biology and evolution.
Common Misspellings for MESOCOELIA
Etymology of MESOCOELIA
The word "Mesocoelia" is a combination of two Greek roots: "meso" meaning middle or intermediate, and "koilos" meaning hollow or cavity. Mesocoelia refers to a middle body cavity or a cavity located between other structures, particularly in organisms such as coelenterates, which have a central body cavity called the coelenteron or gastrovascular cavity.
