METACOEL Meaning and
Definition
-
Metacoel refers to the secondary body cavity found in triploblastic animals, particularly in certain invertebrates such as mollusks, annelids, and nemerteans. This body cavity is distinct from the main body cavity, known as the coelom, that forms during embryonic development. The metacoel is typically a remnant of the embryonic blastocoel, which is the primary body cavity formed during early embryogenesis.
The metacoel is situated between the outer body wall and the digestive tract. It is lined by a layer of mesodermal cells, known as the mesocoel, which separates it from the main coelom. The metacoel is enclosed by the metacoelomic epithelium, a thin membrane that serves as a barrier between the body cavity and the surrounding tissues.
The metacoel plays various roles within the organism. It allows for the movement and expansion of certain organs, such as the gonads, when they are filled with reproductive products. It also serves as a reservoir for waste products, providing a space for their accumulation and subsequent elimination.
In summary, the metacoel is a secondary body cavity found in certain invertebrates, acting as a separate compartment within the organism's overall body plan. It plays a vital role in supporting organ movement, waste storage, and elimination processes.
