evagination

The arciform density is located within the synaptic ridge, a small evagination of the presynaptic membrane.

This primordium begins as an evagination between the first and second pharyngeal grooves, relatively where the anterior two-thirds of the tongue ends.

The human allantois is an endodermal evagination of the developing hindgut which becomes surrounded by the mesodermal connecting stalk.

These pouches are on both sides of the head and are an air-filled out-pouching or evagination to the Eustachian tube, leading into the trachea.

It arises as an anterior evagination of the pineal organ or as a separate outgrowth of the roof of the diencephalon.

Thus, the structural element(s) that are required for localized evagination of membrane appears to be membrane-associated and/or "pulled" from the cytoplasm during the initial bleb formation.

It is formed by two layers of dura mater which are part of an evagination of the tentorium cerebelli near the apex of the petrous part of the temporal bone.

At the present time, we do not know the composition of the membrane that comprise each bleb, or the structural features of the cell that would allow evagination or expansion of these membrane structures at specific sites on the cell surface.

In the equids (horses) and some rodent-like species such as the desert hyrax, an evagination of the eustachian tube is known as the guttural pouch and is divided into medial and lateral compartments by the stylohyoid bone of the hyoid apparatus.

As seen in Fig 5, and in each of these videos, MTX-induced blebbing results in an enormous increase in membrane surface area which may represent stretching of the membrane or an evagination of existing caveolar structures associated with the plasmalemma of endothelial cells.
