Structural Skin with Healthier Me Today! The body’s largest organ, the skin, defends against viruses, controls body temperature, and produces touch (tactile) sensations. The epidermis, dermis, and Hypodermis are the three primary layers of the skin. Skin cancer, acne, wrinkles, and rashes are a few issues that can affect the skin.
What Is The Skin? – Structural Skin
The body’s largest skin organ comprises water, protein, lipids, and minerals. Your skin controls body temperature and guards against infections. Skin nerves enable you to experience emotions like heat and cold.
The integumentary system, which includes your skin, hair, nails, sweat glands, and oil glands, is pronounced: “in-TEG-you-MEINT-a-ree.” The term “integumentary” refers to a body’s skin.
Structural Skin – The Layers of Your Skin
The skin is made up of three tissue layers:
- The epidermis is the outermost layer.
- The middle layer is the dermis.
- The bottom, or fatty layer, is the Hypodermis.
What Does The Top Layer Of Skin Known as The Epidermis Do? – Structural Skin
The top layer of your skin, which you are able to see and touch, is called the epidermis. The skin cells are made of the protein keratin, which joins with other proteins to form this layer. Keratin is a component of skin cells. Skin’s epidermis:
- Serves as a barrier of protection: Infection-causing bacteria and germs are prevented from getting into your body and bloodstream by the epidermis. In addition, it shields from the sun, rain, and other elements.
- Produces new skin cells: The epidermis does this constantly. Your body eliminates about 40,000 old skin cells per day, which these new ones replace. Every 30 days, your skin is renewed.
- Safeguards your body: The epidermis contains Langerhans cells, an immune system component. They aid in the battle against diseases and bacteria.
- Provides skin tone: Melanin, the pigment that gives skin its color, is found in the epidermis. Your hair, eyes, and skin color depending on how much melanin you have. People with darker skin and those who produce more melanin often tan faster.
What Does The Middle Layer Of Skin Known as The Dermis Do? – Structural Skin
90% of the thickness of the skin is made up of the dermis. This skin’s middle layer:
- Contains elastin and collagen: A collagen protein gives skin cells strength and resiliency. Elastin, another protein in the dermis, maintains skin flexibly. It also aids in the form recovery of stretched skin.
- Increases hair: The dermis is where the roots of hair follicles are attached.
- Keeps you connected: Dermal nerves alert you when something is too soft, irritating, or excessively hot to touch. You can also feel pain thanks to these nerve receptors.
- Produces oil: Dermal oil glands contribute to the smoothness and softness of the skin. Additionally, oil stops your skin from absorbing too much water when you swim or are trapped in a downpour.
- Makes You Sweat: Through skin pores, dermal sweat glands emit sweat. Your body temperature is regulated through sweating.
- Provides blood: To maintain the health of the skin layers, blood veins in the dermis supply nutrients to the epidermis.
What Does the Bottom Layer Of Skin Known as The Hypodermis Do? – Structural Skin
The Hypodermis: the fatty layer of skin is located at the bottom of the Hypodermis.
- Muscles and bones are padded: Muscles and bones are shielded from harm by fat in the Hypodermis when you fall or get into an accident.
- Has connective tissue: Layers of skin are joined to muscles and bones by this tissue.
- Supports the blood vessels and nerves: The Hypodermis has more blood vessels and nerves than the dermis (middle layer). The branching out of these blood vessels and nerves joins the Hypodermis to the rest of the body.
- Body temperature control: You don’t get too hot or chilly because of the fat in your Hypodermis.
What Else Makes Up The Skin? – Structural Skin
Your skin has 60,000 melanocytes and about 19 million skin cells per square inch (cells that make melanin or skin pigment). Additionally, it has 20 blood arteries and 1,000 nerve endings.
What Conditions And Disorders Affect The Skin? – Structural Skin
Your skin is susceptible to several issues because it is the body’s external defense system. These consist of the following:
- Allergies are similar to poison ivy rashes and contact dermatitis.
- Various bug bites include spider bites, mosquito bites, and tick bites.
- Skin cancer, such as melanoma.
- Skin infections such as cellulitis.
- Dry skin and skin rashes.
- Skin disorders like eczema, acne, psoriasis, and vitiligo.
- Various skin lesions, such as moles, freckles, and skin tags.
- Wounds, burns (including sunburns), and scars.
How Can I Protect My Skin?
As you get older, you lose collagen and elastin. The dermis, the middle layer of skin, thins as a result. The skin may sag and become wrinkled as a result.
While you cannot stop the aging process, you can take the following steps to maintain younger-looking skin:
- Even if you spend most of the day indoors, use sunscreen daily. Choose a broad-spectrum sunscreen with an SPF of at least 30.
- Don’t sunbathe either inside or outside. Skin damage results from tanning. It can lead to skin cancer and aging of the skin.
- Find appropriate coping mechanisms for stress. Some skin disorders can deteriorate due to stress.
- Check your skin and moles frequently for any changes that could be skin cancer symptoms.
- Give up using tobacco products and smoking. Skin ages more quickly due to nicotine and other substances in cigarettes and electronic cigarettes.
- Wash your face gently both in the morning and at night.
- Apply moisturizer after each shower to avoid dry skin.
When Should I Talk To A Doctor?
If any of the following occur, contact your healthcare professional right away:
- A mole’s size, color, shape, or symmetry changing.
- Skin alterations resemble new moles.
- A wound that won’t heal with an ordinary bandage (that may need stitches).
- Severe burns with blisters.
- Skin infection symptoms such as red streaks or yellow discharge.
- Undiagnosed skin disease or rash.
