I have a strange feeling that you have no clue as to what cytokinesis is.

So to help you out, here is a link on cytokinesis: http://en.wikipedia.org/wiki/Cytokinesis

actually in plant cells it is fairly common for cytokinesis to occur unequally, not in the middle, and distribue more cytoplasm to one daughter cell and less to the other. It is done to create a polarity of the cell.

mitosis = karyokinesis + cytokinesis

I think what you mean is what would happen if karyokinesis sin’t followed by cytokinesis…well, it’s simple…there’ll be a binucleate stadium.. 😆

a syncytium is formed then 😀

Well, not exactly. A syncitium reffers to a group of cells acting as a hole. For example, the smooth muscle cells in the wall of the digestive tube form a syncitium (depolarization in one muscle cell will be followed by depolarization in neighbouring cells and so on). The action potential in a syncitium isn’t conducted through nerve fibers but through the cells themselves. This is done through specialized cell junctions called GAP junctions. These junctions are formed from large numbers of conexones (small protein channels, 6 proteins each called conexines) so ions can flow from a cell to another but not other larger components such as organelles or larege proteins.

No, xand_3r, sdekivit is right. Anatomy books do say that the heart muscle or the muscle cells in the wall of the small intestine function as a syncitium. But the strict definition of a syncitium is a cellular mass with many nuclei that originate in the same nucleus. As opposed to a plasmodium that is composed of many cells that fuse without the nuclei fusing.

I can think that physically, the midplane is the most vulnurable part for cytokinesis due to both right and left mass polarity…But, as like always, excecptions always occur in this kind of situation.. 😆

you don’t have to explain what gap junctions are 🙂 but a syncytium is, as MrMistery already explained, a group of cells that didn’t undergo division of the cell membranes, but only nuclear division.

Examples of syncytia: the syncytiotrophoblast in embryogenesis, the syncytial blastoderm at the early development of Drosophila

–> thus a syncytium is a mass of cells that only underwent nuclear division but not cellular division creating new cells

Yes, you’re right. I forgot about the sincitiotrofoblast. Sorry.

we suppose that cytokinesis occur in mid place bcoz cell has to divide in two halves.it may happen that two halves r not equal bt they are generally comparable.
nd imenwe mytosis must involve cutokinesis.

never mind, even the best makes mistakes 😉
