ectoderm , auch: exoderm , auch: ectoblast

The ectoderm has a greater role in the development of the fetus.

The ectoderm is the start of a tissue that covers the body surfaces.

It is crucial for interactions that occur in the ectoderm at an early stage.

The top layer is now called the ectoderm.

This ectoderm underlies where the cerebral hemisphere will eventually be.

The remainder of the ectoderm gives rise to the epidermis (skin).

This led them to believe that the apical ectoderm may play a role in forming parts of the wing.

Ectoderm is one of the three primary germ cell layers in the very early embryo.

It is these three components of the ectoderm that will each give rise to a particular set of cells.

The ectoderm is formed by the cells of the epiblast.

The neural tube begins as a solid cord formed from the ectoderm.

Evidence for this comes from single, cultured cells of ectoderm, which go on to form neural tissue.

Tough outer integument, an ectoderm with nervous and sensory capacities.

The distal part of the anal canal originates from the ectoderm.

It is formed by ectoderm and endoderm coming into contact with each other.

The ectoderm is the outermost layer of the embryo.

Ectoderm follows a default pathway to become neural tissue.

It is, however, derived from the ectoderm.

The shells develop from the ectoderm as an organic framework which is subsequently mineralised.

It is the animal hemisphere of the blastula that will eventually become the ectoderm.

By the 10 mm stage, the lens vesicle has completely separated from the surface ectoderm.

These cells are in contact with the outer ectoderm cells, which will eventually become the lens.

The lower part (one-third) is derived from ectoderm around the proctodeum.

This means that two embryonic discs could only unite in locations where the ectoderm is absent.

These cells are also derived from epiblast which is transformed into ectoderm.

In the gastrula stage, the segmentation cavity in which the mesoblast is formed lies between the entoblast and ectoblast.
