Study Notes
Mucous Membranes
- Mucous membranes have a main function of protecting the body from foreign substances and pathogens
- They are composed of epithelial tissue, underlying lamina propria, and a layer of smooth muscle
Serous Membranes
- Serous membranes are lined with simple squamous epithelium
- They produce serous fluid, which reduces friction between the membrane and surrounding organs
- They are located in the body cavities, such as the pericardium, pleura, and peritoneum
Skin Layers
- The epidermis is the outermost layer of the skin, and it is avascular
- The most common cell type in the epidermis is keratinocytes
- The stratum corneum is the layer of the epidermis that contains keratinocytes that produce keratin
- The hypodermis (subcutaneous layer) is primarily composed of areolar connective tissue and adipose tissue
- Its main function is to anchor the skin to underlying bones and provide insulation and cushioning
Burns
- The main danger associated with burns is infection and dehydration
- The extent of a burn is estimated by the percentage of affected body surface area
- In a second-degree burn, the epidermis and dermis are damaged
- In burn patients, circulatory shock results from excessive fluid loss
- A first-degree burn is characterized by redness, swelling, and pain
- According to the rule of nines, the palm of the hand represents about 1% of body surface area
- A third-degree burn is characterized by charring of the skin and damage to the hypodermis
- Burns are deemed critical if they affect more than 10% of the body surface area
Skin Cancer
- The most common risk factor for skin cancer is UV exposure
- In skin cancer classification, 'benign' means non-cancerous
- A fourth-degree burn is distinguished from a third-degree burn by the involvement of muscle and bone
- Critical burns are characterized by affecting more than 10% of the body surface area
- Basal cell carcinoma is believed to be induced by UV exposure
- Basal cell carcinoma lesions are characterized by a pearly, waxy appearance
- Malignant melanoma arises from melanocytes and is the most aggressive type of skin cancer
- Squamous cell carcinoma lesions are characterized by a rough, scaly appearance
- Basal cell carcinoma is the least malignant and most common type of skin cancer
- If malignant melanoma is not removed and spreads, it can be fatal
Studying That Suits You
Use AI to generate personalized quizzes and flashcards to suit your learning preferences.
Description
Test your knowledge on the homeostatic imbalances of the skin, focusing on burns, tissue damage, and cell death caused by various factors like heat, electricity, UV radiation, and chemicals. Learn about the associated dangers such as protein denaturation, dehydration, electrolyte imbalance, and circulatory shock.
