Definition

The process where a part of a structure folds inward, often seen in biological development, such as during the formation of certain embryonic layers.

Example

During embryonic development, invagination is crucial for forming the digestive tract.

Conversation

I was reading about embryology, and I came across the term invagination.

Oh really? What does it mean?

It refers to the infolding of a part of the blastula, which is pretty fascinating.

That sounds interesting! Biology has so many complex processes.

Root Explanation

Invagination → It is formed from "in-" (meaning into) and "vaginare" (from Latin, meaning to sheath or to enclose). The word describes the process of folding inward, as if sheathing something within.

Memory Tip

Think of something being folded 'into' ('in-') a 'sheath' ('vaginare') — that's why invagination refers to an inward folding.
