Study Notes
Skin Cells and Pigments
- Melanocytes produce melanin, which determines skin color.
- Pigmentation refers to the coloring of the skin.
- Melanin is the black/brown pigment found in the skin.
- Keratinocytes constitute 90% of epidermis cells, crucial for skin protection.
Skin Layers
- Epidermis: The outer protective layer of the skin.
- Dermis: The layer beneath the epidermis containing connective tissue, hair follicles, and glands.
- Hypodermis: The inner layer beneath the dermis, composed of fat and blood vessels.
- Dermal papillae enhance the connection between epidermis and dermis.
Skin Functions
- Regulation of body temperature through vasodilation (enlargement of blood vessels) and vasoconstriction (narrowing of blood vessels).
- Protection from environmental factors and pathogens.
- Sensation through specialized receptors that detect pressure, touch, and pain.
- Excretion of waste products like uric acid and ammonia through sweating.
- Synthesis of vitamin D upon sun exposure.
Glands and Secretions
- Sebaceous glands produce sebum (oil) to keep skin moist and inhibit bacteria growth.
- Eccrine sweat glands regulate temperature by producing a watery secretion.
- Apocrine sweat glands, located in specific areas, secrete a thicker fluid.
- Ceruminous glands produce earwax (cerumen) found in the auditory canal.
Skin Conditions and Diseases
- Basal cell carcinoma: A common, rarely metastasizing skin cancer originating from the epidermis.
- Squamous cell carcinoma: The most prevalent skin cancer.
- Malignant melanoma: A severe type of skin cancer arising from melanocytes, known for rapid metastasis.
- Dermatitis: Inflammation of the skin, can be caused by various irritants or infections.
Pigmentation Disorders
- Albinism: Condition characterized by the absence of melanocytes and melanin production, leading to pale skin.
- Cyanosis: Bluish skin due to insufficient oxygen in hemoglobin.
- Jaundice: Yellow discoloration of the skin caused by excess bilirubin.
- Erythema: Redness of the skin often related to increased blood flow during exercise.
Hair and Nails
- Vellus hair: Fine, soft hair found on the body, commonly seen in women.
- Hair serves protective roles against environmental elements and provides insulation.
- Nails are composed of tightly packed keratinized cells, contributing to protection and functionality.
Specialized Cells
- Langerhans cells act as immune sentinels in the skin.
- Merkel cells are mechanoreceptors involved in the sensation of touch.
- Free nerve endings detect pain in the skin.
Summary of Skin Components
- Integumentary system: Comprised of skin, hair, nails, and sensory receptors, serving as a protective barrier.
- Skin covers about 2 square meters of the body's surface.
General Facts
- Adipose tissue in the hypodermis provides insulation and energy storage.
- Hemoglobin contributes to skin coloration, showing through in blood vessels within the dermis.
