metaphase

Explanation:

The cell cycle control system initiates chromosome segregation only after metaphase has occurred.

At metaphase, the chromosomes of a dividing cell align at the equator to form what is known as the metaphase plate. Each chromosome gets engaged by spindles from the opposite sides of the poles at the kinetochore of the centromere.

Thereafter, the cell proceeds to the anaphase stage during which the shortening of the spindle fibers pulls the chromosome apart into sister chromatids and this eventually causes the sister chromatids to start migrating to opposite poles of the cell.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.
