Keratinocyte Cell Diagram

Keratinocyte Cell Diagram: The skin is the largest external organ, very important for many process, the most known being that of eliminating toxins through perspiration. The skin of an adult occupies a large area and is made up of epidermis, basement membrane zone, dermis and subcutaneous tissue. These layers have different structures depending on the area of the body. Studies have shown hat each square centimetre of skin has 6 million cells, 15 sebum glands, 5 hairs, 2 heat receptors, 12 cold receptors, 100 sweat glands, as well as 400 cm nerve fibres and 100 cm blood vessels. The epidermis is a semi-permeable barrier, having a layer of flat and anuclear cells at the surface, which is called stratum cornum.

A cell diagram shows how the epidermis regenerates through the division of keratinocytes. A keratinocytes cell diagram shows very well how these protein cells are arranged in layers above the basal layer. Analyzing carefully a keratinocytes cell diagram, we can observe how new keratinocytes are made by new divisions. A keratinocytes cell diagram makes obvious how these cells in the basal layer are pushed upwards the surface of the skin. This means they start to flatten and they die. In a keratinocyte cell diagram is pictured how these cells reach the stratum corneum, exfoliate and then die. The process is called skin renewal and takes place very often and lasts around 30-40 days to complete. A cell diagram can show this process or simple the keratinocytes structure. Through this renewal process, the skin is able to optimize its protective barriers and stay safe for all our lives. Keratinocytes are derrived from ectoderm and produce proteins (keratin), as well as lipids.

Using a cell diagram can make obvious how these cells express adhesion molecules and produce inflammatory cytokines. These cells are polygonal, but will become flat at the surface, having irregular dark keratohyalin granules and thin homogeneous eosinophilic area. Their cytoplasm contains keratin filaments. A cell diagram is always useful as it makes easier to understand the connections between many and very tiny components in a cell. Learning using a cell diagram is very helpful and it takes a shorter time to understand the connections.
