Skin Cell Division Process

In comparison brain and nerve cells seldom reproduce.

Skin cell division process.

The period prior to the synthesis of dna in this phase the cell increases in mass in preparation for cell division. Before a dividing cell enters mitosis it undergoes a period of growth called interphase. The ability of cells to divide is unique for living organisms. Why do cells divide.

Regulation of cell division. For example when you skin your knee cells divide to replace old dead or damaged cells. In the case of skin cells it takes place in the basal layer of the epidermis. The process slows down as you get older but it never stops.

This process is repeated until the cycle is complete. The diagram to the right summarizes events leading to cell division. Cells divide for many reasons. 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.

Cell division occurs through a six phase mitosis process in which a somatic cell divides into two completely identical cells. The original cell is called the mother cell and the two new cells are called daughter cells. We call this process cell division and cell reproduction because new cells are formed when old cells divide. About 90 percent of a cell s time in the normal cell cycle may be spent in interphase.

Desquamation is the natural process in which skin cells are created sloughed away and replaced. This process of renewal is basically exfoliation shedding of the epidermis. The desquamation process happens in the outermost layer of the skin called the epidermis the epidermis itself has four unique layers. 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.

Many cells in an adult are not actively in the process of replicating. After an injury to the skin white blood cells move to the wound followed by various immune cells and then other cells follow. The cells in the superficial or upper layers of skin known as the epidermis are constantly replacing themselves. Skin cells die slough off and are replaced by new skin cells.

The skin possesses three layers. Examples of cells that are produced through mitosis include cells in the human body for the skin blood and muscles. The full process or cycle of mitosis is described in more detail below. Each layer of skin regenerates in response to injury using a different process.
