| 21. | The ostium of the fallopian tube remains from the anterior extremity of the original tubular invagination from the abdominal cavity.
|
| 22. | Optic cup morphogenesis is the invagination process occurring after neuroectoderm movement forms the spherical optic vesicle ( Phase 1 ).
|
| 23. | FSL constructs will not actively pass through the plasma membrane but may enter the cell via membrane invagination and endocytosis.
|
| 24. | It is typically the first step in any invagination process and is also important in folding tissues at specified hingepoints.
|
| 25. | The invagination is pinched off, leaving the engulfed material in the membrane-enclosed vacuole and the cell membrane intact.
|
| 26. | Dens invaginatus is a developmental anomaly resulting from invagination of a portion of crown forming within the enamel organ during odontogenesis.
|
| 27. | It is mechanically easy to convert invaginations of embryos into a " midline " that defines an axis of bilateral symmetry.
|
| 28. | Neural tube cells in " Xenopus " apically constrict during the initial invagination as well as during hingepoint folding.
|
| 29. | Exosomes are formed by invagination within a cell to create an intracellular vesicle called an endosome, or an endocytic vesicle.
|
| 30. | Each arises on the lateral aspect of the corresponding Wolffian duct as a tubular invagination of the cells lining the abdominal cavity.
