Mesoglea (Gr. Mesos - Middle, Gley - Glue)

Mesoglea is a gelatinous substance that is located between the ectoderm and endoderm in coelenterates.

The ectoderm is the outer germ layer from which the integumentary epithelium and nervous system develop.

The endoderm is the inner germ layer that gives rise to the epithelium of the digestive system and respiratory tract.

The mesoglea is located between these two layers and performs a supporting function, maintaining the shape of the body of the coelenterate. It also plays an important role in the processes of morphogenesis, regulating cellular movements and tissue differentiation.

The composition of the mesoglea is heterogeneous. The basis is a jelly-like substance rich in proteoglycans and glycoproteins. The mesoglea also contains cells - amoebocytes, capable of active amoeboid movement.

Thus, mesoglea is an important structural and regulatory component of coelenterates, ensuring the integrity of their body and the coordination of morphogenetic processes.
