Ovum Mesolecithal

Mesolecithal egg - (o. mesolecithale; Greek mesos middle + lekithos egg yolk) - a type of egg in which the yolk is distributed throughout the entire volume of the cytoplasm. This type of egg is typical for fish, amphibians and reptiles.

The yolk in a mesolecithal egg is distributed evenly throughout the cell, in contrast to telolecithal eggs, where the yolk is concentrated at one pole, and oligolecithal eggs, with a small amount of yolk. Thanks to the uniform distribution of the yolk, more efficient nutrition of the developing embryo occurs.

Mesolecithal eggs have an average yolk content. They occupy an intermediate position between the oligolecithal eggs of birds and mammals, and the telolecithal eggs of most fish and many invertebrates.

The mesolecytic ovum is a type of ovum that is found in some species of animals and plants. It differs from other types of eggs in that it is denser and contains a large amount of yolk, a nutrient that ensures the development of the embryo.

The mesolecytic egg also has a larger size and a more rounded shape than regular eggs. It also contains more proteins and fats, which are necessary for the development of the embryo during the first weeks after fertilization.

In some animal species, such as birds and reptiles, mesolecytic eggs are normal and necessary for normal embryonic development. However, in other animal species, for example, mammals, mesolecytic eggs may be a sign of pathology associated with disorders in the development of the embryo or diseases of the mother.

In order to determine whether the mesolecytic egg is normal or pathological, it is necessary to conduct additional studies and tests. This may include analysis of the composition of the yolk in the egg, as well as analysis of the mother's blood and other biological materials to identify possible diseases.

In general, the mesolecytic egg is an important indicator of maternal health and embryo development, and its determination can help in the diagnosis and treatment of various diseases and pathologies.
