    Study Notes

    Acne and Skin Conditions

    • Acne results from excessive production of sebum, leading to clogged pores.
    • Pustules are common lesions associated with acne.
    • Acne vulgaris is the most common form of acne.
    • Eczema is a noncontagious skin inflammation characterized by redness, itching, and lesions.
    • Impetigo is a skin infection caused by staphylococcus bacteria.
    • Boils are pus-filled, blister-like swellings.
    • Herpes causes eruptions of small blister-like vesicles, affecting skin or mucous membranes.
    • Ringworm is a highly contagious fungal infection that presents as raised, itchy, circular patches.
    • Athlete's foot is a fungal infection specifically affecting the feet.
    • Shingles is a viral infection known for causing a painful rash.

    Skin Structure and Functions

    • The integumentary system comprises multiple layers of skin: epidermis, dermis, and subcutaneous (hypodermis).
    • The epidermis is the outermost, keratinized layer serving as a protective barrier.
    • The dermis contains collagen fibers, blood vessels, lymph vessels, nerves, and hair follicles.
    • Hair follicles originate in the dermis and extend through the epidermis to form hair.
    • Sebaceous glands are located in the dermis and secrete an oily substance to nourish skin and hair.
    • Sweat glands serve to excrete waste and regulate body temperature.

    Skin Cells and Cancer

    • Langerhans cells in the skin act as macrophages, defending against microorganisms.
    • Squamous cell carcinoma is a skin cancer arising from the epidermis, commonly found on the scalp and lower lip.
    • Malignant melanoma originates in pigmented cells and is known for rapid metastasis.

    Specialized Skin Features

    • The stratum corneum is the outermost layer of the epidermis, providing protection.
    • Papillae create unique fingerprints through their ridge patterns on the inner surfaces of fingers.
    • The nail matrix is the area where nail growth occurs.
    • Mast cells in the dermis release histamine during allergic reactions, playing a role in immune response.
