TELOLECITHAL Meaning and
Definition
-
Telolecithal is an adjective that describes the characteristic of certain animal eggs. It refers to the distribution of yolk material within the egg, where yolk is mainly concentrated towards one end or pole of the egg. This pattern of yolk distribution distinguishes telolecithal eggs from other types of eggs.
In telolecithal eggs, the yolk serves as the main source of nutrients for the developing embryo. The yolk is often rich in proteins, lipids, and other essential substances required for the growth and development of the embryo. The presence of a concentrated yolk at one end provides a localized supply of nutrients and energy for the developing embryo.
Telolecithal eggs are commonly seen in most reptiles, birds, and monotremes (egg-laying mammals). These animals produce large eggs containing substantial amounts of yolk. The yolk is enclosed within a protective outer shell or membrane, providing support and protection to the developing embryo.
The telolecithal pattern of yolk distribution is significant in the study of embryology and developmental biology. It influences the type of embryonic development an animal undergoes, as well as the overall structure and function of various embryonic tissues and organs.
Overall, telolecithal represents a specific type of egg structure found in certain animals, characterized by significant yolk concentration towards one pole.

Etymology of TELOLECITHAL
The word "telolecithal" is formed by combining two Greek roots: "telos" meaning "complete" or "end" and "lekythos" meaning "egg". "Telolecithal" is a term used in biology to describe an egg or ovum where the yolk is concentrated at one end or pole of the cell. Therefore, etymologically, "telolecithal" refers to an egg with complete or concentrated yolk.
