Study Notes
Functions of the Skin
- The skin is a multifunctional organ with many roles
- Temperature regulation
- Homeostasis/insensible fluid loss
- Protection against UV light
- Physical barrier against trauma
- Sensory perception
- Immune function
Anatomy & Physiology
- Epidermis (outer layer)
- Keratinocytes & Langerhans’ cells contribute to the immune system
- Skin microbiome
- Dermis (middle layer)
- Connective tissue, hair follicles, exocrine glands, neurons & blood vessels
- Subcutaneous/Hypodermis (inner layer)
- Adipose tissue, neurons & blood vessels
Microbiology
- Skin microbiome
- Diverse communities of superficial, deep surface, and adherent microbes
- Dependent on host physiology, environment, immune system, and lifestyle
