Integumentary Skin Protection

Subject: Integumentary Skin Protection

What? The skin provides protection to the underlying tissues from pathogens, mechanical damage, and UV light. If the remains unbroken no pathogens can enter due to the outermost layers of epidermis containing a large supply of dead keratinocytes.

Why? History The skin is an elastic covering. It acts as a protective barrier to the underlying tissues like blood vessels, nerves, and organs. It protects against exposure to dangerous things like bacteria and UV light.

How does it relate to the skin? Keratinocytes begin as offshoots of the stem cells of the stratum germinativum layer. The skin is the largest organ in the human body. Minor damage from rough or sharpened objects is mostly absorbed by the skin before it damages the underlying tissues. Skin is known to be largest organ in the human body. Keratinocytes make up 90% of the epidermis.

Where does it typically occur? Skin covers the body. The first layer of skin under the stratum corneum is the stratum lucidum. The stratum lucidum is found on the palms of the hands and soles of feet which is an interesting fact. It is a protective layer. Skin is the outer covering of the body. The first layer of the skin is the epidermis. The layer we see is a sub-layer of the epidermis called the stratum corneum.

When? Implications Skin color is controlled by 3 pigments: melanin, carotene, and hemoglobin. Melanin is produced by melanocytes in the stratum germinativum to protect the skin from UV rays. The color of our skin is not only determined by the melanin, but also the carotene and hemoglobin. Melanin is a brown to black pigment in the skin.

Who benefits from this? All humans. With the constant replacement and reproduction occurring in the cell, older cells are sent to aid the repair of injuries in the body. Everyone benefits from this because without skin, our underlying tissues would be exposure.

What causes this? –The human body has trillions cells that operate differently. Cells actually group together to form tissues, organs and systems. Since the body has trillions and trillions of cells that all have different jobs or duties, those cells group together and form the tissues, organs, and systems in our bodies.

How? Solutions (Mechanical /Machines) Machines can change the function of the skin layers. Electrical equipment can actually stimulate the cells in the dermis to make collagen. There are different machines that can stimulate the cells in the skin and produce more. It would stimulate the cells in the dermis layer.

How? Solutions (Non Mechanical) This protection explains the necessity of cleaning, covering cuts with bandages to prevent infection, and not picking at pimples. Do not pick at pimples. Use band aids to cover cuts, and clean the skin daily is necessary to a healthy body.
