Evagination vs. Invagination — What's the Difference?

Endodermic evagination

In developmental biology, invagination is a mechanism that takes place during gastrulation. This mechanism or cell movement happens mostly in the vegetal pole.

To cause (a body part) to turn inside out by eversion of an inner surface.

The action or process of being turned inside out or folded back on itself to form a cavity or pouch.

The act of evaginating.

The act or process of invaginating or the condition of being invaginated.

An outgrowth or protruded part.

An invaginated organ or part.

The act of unsheathing.

(Embryology) The infolding of a portion of the outer layer of a blastula in the formation of a gastrula.

An outgrowth or protruded part.

(medicine) The process where an anatomical part invaginates upon itself or into another structure.

One of the methods by which the various germinal layers of the ovum are differentiated.

The condition of an invaginated organ or part.

The inward movement of the wall of a tissue or cell, to form a cavity; also, the cavity thus formed.

The inward movement of one part of the wall of a blastula, to form a gastrula; the process of gastrulation, in which layers of the ovum are differentiated.

The condition of being folded inward or sheathed

The folding in of an outer layer so as to form a pocket in the surface;
