The tapering inferior end of the spinal cord is called the conus medullaris . This structure marks the official "end" of the spinal cord proper (usually at the level of the first lumbar vertebra). Inferior to this level, nerve roots collectively called the cauda equina project inferiorly from the spinal cord. These nerve roots are so named because they resemble a horse’s tail. Within this "horse’s tail" is the . This is a thin strand of pia mater that helps anchor the conus medullaris to the Coccyx.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

this is more of a statement than a question. is there answers to go along with this, or is it opinion based?
