LUSL 4084 SKIN 1
Week 4: Integumentary System
1. Anatomy and Physiology
Skin ◻
- Largest sensory organ
- Layers: Epidermis, Dermis, Hypodermis
(subcutaneous fat)
- Epidermal appendages (nail, hair, glands).
- Normal bacterial flora (gram -/+ staphylococci)
Functions ◻ Acts as the first line of defense against
infection, protects underlying tissue and organs,
receives stimuli, regulates body temp, excretes salt,
water, and waste, synthesizes Vit D3, stores nutrients.
2. Risk factors for Integ Disorders
◻ Exposure to chemical and environmental pollutants
◻ Exposure to Radiation
◻ Race and age
◻ Exposure to sun (indoor tanning)
◻ Harsh skin products and some medications
◻ Repeated injury
◻ Nutritional deficiencies
◻ Systemic injury
3. Psychosocial Impact
◻ Change in body image, decreased well-being and self-
esteem
◻ Social isolation and fear of rejection
◻ Pain
◻ Cost of medication, hospitalizations, follow up care
4. Phases of Would Healing
1. Inflammatory: Time of injury lasts 3-5 days (edema,
pain, redness, and warmth)
2. Fabroblastic: 4 days after injury lasts 2-4 weeks (scar
tissue)
3. Maturarion: Begins as earl as 3 weeks and lasts for 1
year (scar tissue thinner)
Healing by Intention:
1. First intention: Wound edges are approx and held in
place.
2. Second intention: Occurs with tissue loss, gradual filling
in of the dead space with CT.
3. Third intention: Delayed primary closure,
intentionally left open for several days for

irrigation, removal of debris and exudates.
5. Diagnosis Test
◻ Skin biopsy (keep dressing on for 8 hours post
procedure)
◻ Skin and wound cultures, viral culture is placed
immediately on ice
◻ Wood’s light exam (skin viewed under UV light
through glass to identify superficial infections
under the skin)
◻ Diascopy (glass slide over lesion, allows clear
inspection of lesion eliminating erythema)
