Integument Exam Practice Notes

Surface Skin Cell Regeneration
Regeneration occurs in the stratum basale, the deepest epidermal layer housing highly mitotic cells.
Stratum Lucidum Location
This layer is exclusive to the thick skin found on the palms and soles, situated between the stratum corneum and stratum granulosum.
Resistance to Tearing
The reticular layer of the dermis contains a network of collagen fibers, providing strength and resistance when the skin is stretched.
Epidermal Sensory Receptors
Tactile cells, also known as Merkel cells, serve as sensory touch receptors located at the epidermis-dermis border.
Rule of Nines for Burns
This method estimates burn coverage by dividing the body into 11 regions, each accounting for approximately 9% of total body surface area, aiding in assessing burn severity.
Characteristics of Third-Degree Burns
These burns are full-thickness, affecting all layers of the skin, leading to significant tissue damage.
Health Risks from Serious Burns
Significant fluid loss from serious burns can lead to kidney failure and circulatory shock due to the disruption of skin's fluid retention capabilities.
Treatment for Critical Burns
Treatment for serious burns does not include applying ice or cold pads; instead, it focuses on other critical medical interventions.
Post-Sunburn Redness
Redness following a sunburn is due to inflammation and increased blood flow to the affected skin area.
Pain Sensation in Burns
Third-degree burns may be less painful than first- or second-degree burns because they destroy the pain receptors in the skin.

Test your knowledge of integumentary systems with these practice questions based on Exam 2 material. Focus on the structure, function, and layers of the skin, including the epidermis and its regeneration processes. Perfect for students preparing for anatomy assessments.
