How Do You Spell VITELLINE MEMBRANES?

1. Vitelline membranes are a pair of protective layers that surround the yolk of an egg. These membranes are found within the eggshell and serve several important functions in embryonic development.

   The vitelline membranes are made up of two distinct layers – the inner and outer membranes. The outer membrane is a thicker, more rigid layer, while the inner membrane is thinner and more delicate. Together, they create a barrier that shields the yolk and provides structural support.

   One of the main functions of the vitelline membranes is to provide protection for the developing embryo. They act as a shield against mechanical damage, preventing the yolk from rupturing or being damaged during movements inside the eggshell. Additionally, the membranes help to maintain the yolk in its proper position, preventing it from shifting or floating within the egg.

   Another important role of the vitelline membranes is to facilitate gas exchange. These membranes are permeable to gases, allowing oxygen to enter the egg and carbon dioxide to exit. This exchange of gases is crucial for the developing embryo's respiration.

   Furthermore, the vitelline membranes aid in the absorption of nutrients by the developing embryo. They act as a barrier between the yolk and the albumen (egg white) to prevent unnecessary diffusion of nutrients, ensuring proper nutrient utilization by the growing embryo.

   In summary, vitelline membranes are protective layers that surround the yolk of an egg. They provide physical protection, maintain yolk position, facilitate gas exchange, and aid in nutrient absorption during embryonic development.

Common Misspellings for VITELLINE MEMBRANES

The word "Vitelline Membranes" comes from the combination of two terms: "Vitelline" and "Membranes".

1. Vitelline: The term "Vitelline" is derived from the Latin word "vitellus", which means "yolk". It refers to the yolk of an egg. In biological terms, the vitelline refers to substances or structures related to the yolk.

2. Membranes: The term "membranes" comes from the Latin word "membrana", meaning "thin skin" or "layer". In biology and anatomy, membranes refer to thin layers or films of tissue that cover or separate parts of the body.

By combining these two terms, "Vitelline Membranes" refers to the thin layers or membranes associated with the yolk of an egg or structures related to it.
