This modern wound care device consists of two layers-the upper layer mimics the epidermis and the layer underneath is a porous matrix which replaces the dermis. The top temporary epidermis is made of silicone which provide immediate physiological closure preventing fluid and heat loss along with functioning as a bacterial barrier. The underlying matrix layer consists of cross-linked

It follows that water will move from a region of high water concentration to a region of low water concentration therefore‚ if a cell is placed in a hypertonic solution water will move from the cell into the solution until the

Staining‚ as it is highly dependent (McCarthy‚ 25). In the specific experiment that was done‚ Gram Staining was used and the bacteria that was found was purple and round (cocci) shaped. Through this the bacteria was identified as Staphylococcus epidermis. Material and Methods: The first step to identifying the bacteria was to heat fix it to the slide. The materials used were a slide‚ water‚ a Bunsen Burner‚ bibulous paper and clothes pin. The unknown bacteria was in a vial in solid form. The steps

Skin is the largest organ in the human body. It is made up of three layers‚ the epidermis‚ dermis and the hypodermis. The epidermis is the outer layer of skin that keeps out harmful germs and bacteria but keeps in the vital fluids that humans need to survive. The dermis is the inner layer of skin that contains blood vessels‚ nerves‚ hair follicles‚ oil‚ and sweat glands Until the late twentieth century‚ skin grafts were constructed from the patient’s own skin. Traditional ways of dealing with large

an impression of friction ridges. A friction ridge is a raised portion of the epidermis on the digits (fingers and toes)‚ the palm of the hand or the sole of the foot‚ consisting of one or more connected ridge units of friction ridge skin. These are sometimes known as "epidermal ridges" which are caused by the underlying interface between the dermal papillae of the dermis and the interpapillary (rete) pegs of the epidermis. These epidermal ridges serve to amplify vibrations triggered‚ for example‚

At that point after surgically cutting through the first three layers of skin I would be at her periosteum of compact bone‚ then

Type of cancer. Melanoma is a skin cancer that originates in the melanocytes‚ a type of cell that makes up the skin. Skin is formed by three layers: epidermis‚ dermis and subcutaneous tissue. Melanocytes‚ together with keratinocytes‚ are part of the epidermis and are responsible for producing melanin‚ a pigment that protects against the damaging effects of sunlight. The formation of melanin - melanogenesis is a biochemical process carried out by melanocytes and is affected by several hormones: α-melanocyte-stimulating

leaves along a water source and away from a water source was to analyze the stomatal density difference. This experiment was performed to measure which environment had a greater effect on stomatal density. Stomata of a leaf is a miniature pore in the epidermis of a leaf surrounded by guard cells that have a slit which allow movement of gases in and out of the leaf. With stomata‚ when it opens carbon dioxide enters a leaf while water and dioxide exit the leaf. (Reece‚ Taylor‚ Simon‚ Dickey‚ Hogan‚ 2015)
