Dental Embryology Terminology
Term | Definition |
---|---|
Prophase of Mitosis | Chromatin thread shortens and thickens and becomes chromosomes. Chromosomes then split into pairs of chromatids. Nuclear membrane disappears and centrioles appear and begin migrating to opposite poles of cell. |
Anaphase of Mitosis | Division and movement of completed identical sets of chromatids (chromosomes) to opposite ends of cell. |
Metaphase of Mitosis | Centromeres and chromatids line up in middle of cell. |
Telophase of Mitosis | Nuclear membrane reappears, nucleoli appear, and chromosomes lengthen and form chromatin thread. |
Meiosis | Process of reduction of the number of chromosomes to half the normal number in the germ cells to allow fusion of the male and female germ cells. |
