Ovum Isolecithal

An isolecithal ovum is an egg that contains a small amount of yolk. It is a form of egg and is found in some species of animals and plants.

Isolecithal eggs are formed when the yolk does not fully develop in the egg. This may be due to various factors such as genetics, environmental conditions or the age of the animal.

Although isolecithal ova are found in many animal and plant species, they are not the norm in all. In most cases, the eggs contain enough yolk for embryo development.

Isolecithal type eggs have their advantages and disadvantages. On the one hand, they can provide the embryo with sufficient nutrients in the early stages of development. However, if the yolk is not sufficiently developed, this can lead to problems with embryo development and reduced embryo survival.

In general, isolecithal type eggs are found in various species of animals and plants and have their own characteristics. They may be beneficial to some organisms, but may also cause problems for embryonic development.

ISOLECITAL type eggs

The isolecytic egg has the shape of a circle or oval, with features similar to those of eggs with a homeological type of histogenesis. In the central part there is a small depression called a fossa. The development of other characteristics, such as yolk accumulation and trophoblast formation, occurs in a normal manner. However, during the first pregnancy, difficulties can be expected due to delayed ovulation, as well as disruption of distraction, which can only be prevented depending on the presence of a certain degree of uterine activity.

The development of these features occurs with disease of the heteropolar organs of the mother, i.e. genital organs of a woman (for example, in the case of polycystic ovaries with Schmidt-Leventhal syndrome). Like cyclic histogenesis tissue, they arise from a disruption of the normal formation and arrangement of yolk cells within the so-called inner layer membranes of the microscopic yolk cell line. These membranes are rigid and are responsible for forming the outer shape and housing the yolk material within the yolk sac. In other words, the lining of the inner layer of the ovary does not reorganize properly, resulting in the absence of another type of egg, such as radial mesolecitis.
