How Do You Spell VITELLINE SAC?

Pronunciation: [vˈa͡ɪtə͡lˌa͡ɪn sˈak] (IPA)

The correct spelling of the term "Vitelline Sac" is pronounced /vɪˈtɛlaɪn sæk/. The word "vitelline" is derived from "vitellus," the Latin word for yolk, while "sac" refers to a pouch or sac, resulting in an anatomical structure that contains the yolk in a developing embryo. The use of phonetic transcription, such as IPA, helps clarify the spelling and pronunciation of complex scientific terms frequently used in anatomy and physiology, permitting better communication and understanding.

VITELLINE SAC Meaning and Definition

1. The vitelline sac, also known as the yolk sac, is a membranous structure found in the eggs of most vertebrates, including fish, reptiles, birds, and monotremes. It is an essential component of the early embryonic stage and plays a crucial role in supporting the growing embryo.

   The vitelline sac is connected to the embryo by a region called the yolk stalk or omphalomesenteric duct. Through this connection, the sac provides vital nutrients to the developing embryo, including proteins, lipids, and minerals that are stored in the yolk. These nutrients are essential for the embryo's growth and development until it becomes capable of obtaining food independently.

   In addition to nourishing the developing embryo, the vitelline sac also serves as a site for temporary waste storage. It accumulates waste products produced by the embryo and eventually aids in their elimination from the body.

   As the embryo matures, the vitelline sac gradually decreases in size, gradually being replaced by other structures that take over the role of nutrient provision. In most mammals, including humans, the vitelline sac is highly reduced and does not play a significant role in embryonic development.

   Overall, the vitelline sac is a crucial structure in the early stages of vertebrate development, providing essential nutrients and facilitating waste elimination for the growing embryo.

Etymology of VITELLINE SAC

The word "Vitelline" is derived from the Latin term "vitellus", which means "yolk". The term "sac" comes from the Latin word "saccus", meaning "bag" or "sack". In embryology, the vitelline sac, also known as the yolk sac, refers to a membranous sac that surrounds the yolk in the early stages of development of an embryo. It provides nutrients to the developing embryo before the placenta forms. The term "Vitelline Sac" combines these two Latin words to describe the sac containing the yolk.
