  • It covers the tips of the fingers and toes. It is made up of sheets of hardened keratinocytes.
    nails
  • Keeping the skin clean and dry, avoiding sharing personal items, and wearing breathable fabrics.
    Prevention of Fungal Infections
  • Thermal damage
    Detected by hot, cold, and pain sensory receptors in the skin.
  • Chemical damage
    Blocked by specialized keratin cells in the upper layer of the skin.
  • It anchors the hair into the skin. It regulates hair growth.
    hair follicle
  • A small-oil producing gland found in the dermis. It is attached to the hair follicles. It produces oil sebum and waxy substance.
    sebaceous gland
  • A highly contagious skin infection caused by bacteria, most often affecting children.
    Impetigo
  • Skin
    The largest organ of the body that protects and covers the internal organs from the external environment.
  • It is linked to genetic and environmental factors, including allergens, irritants, and stress.
    Eczema
  • Functions of the integumentary system
    Protects deeper body organs from physical, chemical, thermal damage, UV radiation, and bacteria.
  • What is the thickest layer of the skin?
    dermis
  • Physical damage
    Bumps and cuts that are cushioned by fat cells and alerted by pressure receptors.
  • What is the deepest layer of the skin?
    hypodermis
  • the abnormal growth of skin cells, often due to excessive exposure to ultraviolet (UV) radiation.
    Skin Cancer
  • Main function of the skin
    To protect and cover the internal organs of the body from the external environment.
  • Dermis
    A strong and stretchy layer of skin made up of the papillary layer and the reticular layer.
  • What is the outermost layer of the skin that covers almost entire body surface?
    epidermis
  • Hair
    Scattered all over the skin, providing minimal protection and produced by hair follicles.
  • An autoimmune condition that causes the rapid buildup of skin cells, leading to scaly patches.
    Psoriasis
  • Oil glands
    Produce sebum to keep the skin soft and moist, and contain chemicals that kill bacteria.
  • the most dangerous type of skin cancer, arising from the pigment-producing melanocytes.
    Melanoma
  • Occur when fungi overgrow on the skin, typically in warm, moist areas.
    Fungal Infections
  • A chronic condition that causes patches of skin to become inflamed, itchy, and cracked.
    Eczema (Atopic Dermatitis)
  • It helps produce body sweat, oil wax, helps cool down the skin surface, helps protect the skin, and moisturize the skin surface.
    exocrine glands
  • Epidermis
    Composed of five layers of skin, primarily keratin cells that produce tough keratin.
  • What is the foundation of the integumentary system?
    skin
  • Integumentary system
    The skin and its accessory structures, including oil and sweat glands, hair, and nails.
  • Collagen and elastin fibers
    Decrease with age, causing the skin to sag and wrinkle.
  • Bacteria
    Destroyed by acidic skin secretions and immune cells if it enters through an open wound.
  • It is a small tubular structure of the skin that produce sweat found in the dermis and goes out of the skin pores.
    sweat gland
  • refers to skin inflammation, often caused by allergic reactions or irritants.
    Dermatitis
  • Eccrine glands
    Widely distributed sweat glands that respond to internal and external temperature changes.
  • Structure of skin
    Made up of the epidermis (outer layer) and the dermis (second layer of dense connective tissue).
  • Nails
    Scale-like extensions of the epidermis made of keratin, with no real function in the integumentary system.
  • It is a layer of clear skin located at the bottom edge of the fingers and toes.
    cuticle
  • Sweat glands
    Eccrine and apocrine glands that secrete sweat to regulate body temperature.
  • Apocrine glands
    Larger sweat glands found in genital areas, playing a minimal role in regulating body temperature.
  • UV radiation
    Partially protected against by melanin produced by the skin.
  • A common skin condition that occurs when hair follicles become clogged with oil and dead skin cells.
    Acne
  • Accessory structures of the skin
    Include oil and sweat glands, hair, and nails.
