Quiz 5 Integ Flashcards
Function of epidermis
- Outermost layer of the skin
- Primarily composed of keratinocytes which produce the protein keratin
Keratin: Makes our skin waterproof and provides protection against environmental waste
What layer is filled with keratin
Stratum Corneum
What are sebaceous oil glands
- Part of the dermis
- Produce sebum which lubricants the hair and surface of the skin
What sweat glands play a primary role in Thermoregulation?
Eccrine Sweat Glands
What is the hypodermis
It binds the skin to the underlying tissues
- Acts as an insulator, conserving body heat and protecting the body from mechanical shocks
What is the most visible part of the nail
Nail Plate
Function of the nail
1) Protection
2) Enhanced Sensation
3) Manipulation
4) Temperature Regulation
What is the primary function of sebaceous glands?
The production of sebum, an oily, waxy substance composed of triglycerides, cholesterol, proteins, and inorganic salts
Why do eccrine sweat glands produce sweat?
In response to elevated body temperature
What happens when the skin is exposed to UVB rays from sunlight?
It synthesizes vitamin D
Transepidermal Water Loss
- Refers to the water that passively evaporates from the skin
- Maintaining a balance in TEWL is essential to keep the skin hydrated and prevent dryness
Where does Repair and Growth begin?
Stratum Basale
4 Parts of Proliferation:
1) Collagent synthesis
2) Wound Contraction
3) Epithelialization
4) Angiogenesis
Pressure Wounds
Pathology: Caused by unrelieved pressed on the skin leading to tissue ischemia
Signs and Symptoms: Redness,pain,swelling, skin breakdown
Medical Mangament: Pressure relief
Diabetic Ulcers
Pathology: Caused by neuropathy and peripheral arterial disease in diabetes
Signs and Symptoms: Commonly on foot soles, painless due to neuropathy, surrounded by calloused skin
Medical Management: Topical treatments, wound dressings, surgical grafting
