    en.wikipedia.org/wiki/Visual_cortex

    In terms of anatomy, V2 is split into four quadrants, a dorsal and ventral representation in the left and the right hemispheres. Together, these four regions provide a complete map of the visual world. V2 has many properties in common with V1: Cells are tuned to simple properties such as orientation, spatial frequency, and color.

  3. Cell division - Wikipedia

    en.wikipedia.org/wiki/Cell_division

    At the peak of the cyclin, attached to the cyclin dependent kinases this system pushes the cell out of interphase and into the M phase, where mitosis, meiosis, and cytokinesis occur. [19] There are three transition checkpoints the cell has to go through before entering the M phase. The most important being the G 1-S transition checkpoint. If ...

    en.wikipedia.org/wiki/Cell_isolation

    Cell isolation is the process of separating individual living cells from a solid block of tissue or cell suspension. While some types of cell naturally exist in a separated form (for example blood cells ), other cell types that are found in solid tissue require specific techniques to separate them into individual cells.

    A mature individual consists of up to a thousand [clarification needed] cells that can be divided into four different cell types. The monociliated cells of the dorsal epitheloid are flattened and contain lipid bodies. The cells on the ventral side likewise possess a single cilium, while their elongated columnar shape, with a small cross section ...

  9. Hayflick limit - Wikipedia

    en.wikipedia.org/wiki/Hayflick_limit

    As the cell divides, the telomeres on the ends of chromosomes shorten. The Hayflick limit is the limit on cell replication imposed by the shortening of telomeres with each division. This end stage is known as cellular senescence. The Hayflick limit has been found to correlate with the length of the telomeric region at the end of chromosomes.
