Dialogue. The call.
Ivanov: you know i think that various organs consist of cells. is ther structure similar?
Brown: Well, at first the cells develop by a division of one cell into two cell, and then these two cells are divided into four cells and so one. In the growth of the tissues and organs there appear different cells with different functions
Ivanov: Oh, but how can it be? Do the cells differentiate greatly?
Brown:You see, the cell in the nervous system send out long processes to form the nerves, those in the muscles become long and striped in appearance, and those which form fat become filled with fat droplets which distend the cells
Ivanov: And what about the cells in future bones, tendons, cartilages? Are they also different to a certain extent?
Brown:You are quite right. Thus, in the future bones, some cells deposit lime salts, and others from cartilage; while in tendons, they product long white fibers of a gelatinous substance
Ivanov: Are there any cells that change little or retain their primitive characters?
Brown: In some organs the cells change little, for example, in liver, and the white blood corpuscles retain their primitive characters most entire. Tumors, especially malignant ones, have a highly cellular structure. And their cells are either of embrionic type or, at best, form poor imitations of the tissues in which they grow
Ivanov: Oh, this information is rather interesting! Thank you very much
