    Study Notes

    Integumentary System

    • The integumentary system is the body's outer layer, consisting of skin, hair, nails, and glands.
    • Skin is composed of three layers:
      • Epidermis: the thin, outer membrane layer.
      • Dermis: the middle, fibrous connective tissue layer.
      • Subcutaneous layer (hypodermis): the innermost layer of fatty tissue.

    Skin Conditions and Diseases

    • Dermatology: the branch of medicine dealing with skin diseases.
    • Dermatitis: inflammation of the skin.
    • Dermatophytosis: skin infection by dermatophytes (fungi).
    • Leukoderma: a localized area of white depigmented skin due to melanin loss, often after a burn or trauma.
    • Keratosis: localized horny overgrowth of the skin, such as warts or calluses.
    • Keratolytic: a compound used to remove excess keratin.
    • Hypertrichosis: excessive hair growth in areas it is uncommon, in both men and women.
    • Piloerection: hair raising/erection.
    • Pilomotor muscle: the muscle causing hair erection.
    • Onychomycosis: fungal infection of the nail.
    • Paronychia: inflammation of the tissues surrounding the nail.
    • Sebum: natural oily substance that protects the skin.
    • Seborrhea: a common non-contagious skin condition with excess sebum secretion.

    Additional Skin Terminology

    • Melano (dark or black):
      • Melanocyte: melanin-producing cells.
      • Melanoma: cancerous tumour of melanocytes.
    • Skin Conditions:
      • Diaphoresis: excessive sweating.
      • Hirsutism: excessive dark hair growth in areas common to women.
      • Photosensitivity: skin reaction to light.
      • Pruritus: severe itching
      • Vitiligo: chronic autoimmune loss of skin colour in patches.
    • Skin Diseases:
      • Abscess: collection of pus in skin.
      • Acne: inflammatory disease of sebaceous glands and hair follicles.
      • Scabies: infectious skin disease caused by a parasite.

      • Psoriasis: chronic, scaly, and often itchy skin disease.
      • Tinea: fungal skin infection.
      • Warts: epidermal growth due to viral infection.

    Cancer Terminology

    • Carcinogenic agent: substance causing cancer.
    • Precancerous lesion: lesion that may transform into cancer.
    • Carcinoma: malignant cancer arising from epithelial cells (skin, organs, and glands).
    • Sarcoma: malignant cancer arising from connective tissues (bone, muscle, cartilage, or fat).

    Tumour Types

    • Lipoma: benign tumor originating from fat.
    • Fibroma: benign tumor originating from fibrous tissue.
    • Myoma: benign tumor originating from muscle tissue.
    • Osteosarcoma: malignant tumor originating from bone.

    Diagnostic Procedures

    • Biopsy: taking a tissue sample for examination:
      • Incisional: taking part of the tissue.
      • Excisional: removing the whole lesion.
      • Needle: extracting a small sample with a needle.
