Skin Cell Division Process

The process slows down as you get older but it never stops.

Skin cell division process.

In comparison brain and nerve cells seldom reproduce. The cells in the superficial or upper layers of skin known as the epidermis are constantly replacing themselves. This is depicted in the diagram as cells that cease division also known as the g 0 phase or the resting phase the term resting phase is a misnomer however. The full process or cycle of mitosis is described in more detail below.

The original cell is called the mother cell and the two new cells are called daughter cells. Each layer of skin regenerates in response to injury using a different process. Many cells in an adult are not actively in the process of replicating. Skin cells belong in the category of somatic cells and are duplicated at a rapid rate during life.

We call this process cell division and cell reproduction because new cells are formed when old cells divide. Skin cells die slough off and are replaced by new skin cells. The skin possesses three layers. About 90 percent of a cell s time in the normal cell cycle may be spent in interphase.

Regulation of cell division. Cells divide for many reasons. Desquamation is the natural process in which skin cells are created sloughed away and replaced. Before a dividing cell enters mitosis it undergoes a period of growth called interphase.

This process of renewal is basically exfoliation shedding of the epidermis. Mitosis is a type of cellular division in which one cell called the parent divides into two identical daughter cells reports dawn tamarkin ph d of springfield technical community college. Why do cells divide. The desquamation process happens in the outermost layer of the skin called the epidermis the epidermis itself has four unique layers.

The ability of cells to divide is unique for living organisms. The period prior to the synthesis of dna in this phase the cell increases in mass in preparation for cell division. Skin cells grow and divide in the basement membrane. The deepest layer is the subcutis which is beneath the dermis and the outermost layer is the epidermis.

For example when you skin your knee cells divide to replace old dead or damaged cells. Examples of cells that are produced through mitosis include cells in the human body for the skin blood and muscles. Cell division occurs through a six phase mitosis process in which a somatic cell divides into two completely identical cells. In the case of skin cells it takes place in the basal layer of the epidermis.
