The term "vitellus nutritivus" refers to the nutrient-rich yolk of an egg. Its spelling can be explained through the International Phonetic Alphabet (IPA) phonetic transcription. The initial "v" is pronounced as /v/, the "i" as /ɪ/, the "t" as /t/, the "e" as /ɛ/, the double "l" as /lː/, the "u" as /u/, and the final "s" as /s/. The stress falls on the third syllable, with the accent /ˈnu.tri.ti.vus/. Understanding the IPA helps to correctly pronounce and spell words, especially those with challenging spellings or pronunciations.
Vitellus nutritivus, also known as the nutritive yolk or egg yolk, is a term predominantly used in biological sciences, specifically in the field of embryology and zoology. It refers to the nutrient-rich substance found in the egg of animals, particularly in oviparous species.
The vitellus nutritivus constitutes the primary source of nourishment for the developing embryo during its early stages of development. It contains various essential components vital for the growth and development of the embryo, such as proteins, lipids, minerals, vitamins, and other nutrients.
The size and composition of the vitellus nutritivus can vary across different species, depending on their reproductive strategies and the energy requirements of the developing embryos. Some species may have larger yolk reserves, resulting in more significant energy stores available to sustain the embryo throughout its development.
In addition to providing nourishment, the vitellus nutritivus also serves as a protective medium for the developing embryo, providing a physical barrier against external shocks and temperature fluctuations. It also acts as a source of immune factors that aid in the defense against potential pathogens.
Overall, the vitellus nutritivus plays a vital role in the reproductive process of animals by ensuring the adequate provision of nutrients to support the growth and development of embryos until they are sufficiently developed to survive independently.

The term "vitellus nutritivus" is a Latin phrase that translates to "nourishing yolk" in English.
- "Vitellus" is derived from the Latin word "vitreolus", which means "the yolk of an egg". It comes from the Latin word "vitreus", referring to "glass". This is because the yolk of an egg has a similar appearance to glass.
- "Nutritivus" is derived from the Latin word "nutrire", which means "to nourish" or "to feed". It is the source of the English word "nutrition".
When combined, "vitellus nutritivus" refers to the yolk of an egg, which serves as a source of nourishment for the developing embryo.
