Skin Cell Division Process

This process of renewal is basically exfoliation shedding of the epidermis.

Skin cell division process.

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. The process slows down as you get older but it never stops. The ability of cells to divide is unique for living organisms.

Skin cells die slough off and are replaced by new skin cells. Skin cells grow and divide in the basement membrane. The cells in the superficial or upper layers of skin known as the epidermis are constantly replacing themselves. The skin possesses three layers.

In comparison brain and nerve cells seldom reproduce. The diagram to the right summarizes events leading to cell division. 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. About 90 percent of a cell s time in the normal cell cycle may be spent in interphase.

Regulation of cell division. The full process or cycle of mitosis is described in more detail below. We call this process cell division and cell reproduction because new cells are formed when old cells divide. The desquamation process happens in the outermost layer of the skin called the epidermis the epidermis itself has four unique layers.

In the case of skin cells it takes place in the basal layer of the epidermis. Each layer of skin regenerates in response to injury using a different process. This process is repeated until the cycle is complete. The period prior to the synthesis of dna in this phase the cell increases in mass in preparation for cell division.

Many cells in an adult are not actively in the process of replicating. 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. After an injury to the skin white blood cells move to the wound followed by various immune cells and then other cells follow. Skin cells belong in the category of somatic cells and are duplicated at a rapid rate during life.

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. Cells divide for many reasons. Desquamation is the natural process in which skin cells are created sloughed away and replaced.
