Understanding Skin and Body Membranes: Structure, Function, and Disorders

This comprehensive overview explores the classification and functions of body membranes, focusing on epithelial and connective membranes, including cutaneous, mucous, and serous types. Delve into the structure of the skin, comprising the epidermis, dermis, and hypodermis, highlighting their layers and cell types like keratinocytes and melanocytes. Learn about skin color influences, appendages, and common disorders, including burns, infections, and skin cancer types. Additionally, we discuss the developmental aspects of skin throughout the life cycle, from fetal development to aging changes.

Presentation Transcript

  1. A&PChapter 4 Notes Skin and body membranes

  2. Classification of Body Membranes • Epithelial Membranes • Cutaneous • Mucous • Serous • Parietal layer • Visceral layer • Connective Membranes • Synovial

  3. Typical Synovial Joint

  4. Integumentary System Skin (cutaneous membrane) and derivatives Mostly protective function Epidermis, dermis, hypodermis

  5. Epidermis • 5 layers (strata) • Stratum basale • Spinosum • Granulosum • Lucidum • Corneum • Avascular • Keratinocytes • Melanocytes

  6. Dermis • “hide” • Collagen, Elastin, Phagocytes • Papillary layer • Dermal papillae • Meissner’s corpuscles • Papillary patterns • Reticular layer • Blood vessels, sweat and oil glands • Pacinian corpuscles

  7. Skin Color • Three pigments contribute to skin color • Melanin • Carotene • Oxygen bound to hemoglobin • Homeostatic Imbalances: • Erythema • Pallor • Jaundice • Bruises

  8. Appendages of the Skin • Cutaneous glands • Exocrine glands • Sebaceous glands • Sweat glands • Hairs and hair follicles • Root • Shaft • Hair bulb matrix • Arrectorpili • Nails • Free edge, body, root

  9. Homeostatic Imbalances of Skin • Infections and Allergies • Athletes foot • Boils • Cold sores • Contact dermatitis • Impetigo • Psoriasis

  10. Homeostatic Imbalances Cont’d • Burns • Rule of nines • 1st degree • 2nd degree • 3rd degree

  11. Severity of Burns 1st degree 2nd degree 3rd degree

  12. Skin Cancer • Basal cell carcinoma • Squamous cell carcinoma • Malignant melanoma • ABCD rule

  13. Developmental Aspects of Skin and Body Membranes • Fetal - Baby • Lanugo • Vernixcaseosa • Milia • Adolescence • Acne • Dermatitis • Old age • Subcutaneous tissue decrease (cold) • Drier skin • Bags and jowls • Alopecia and graying hair (delayed gene)
