Name each of the five sublayers of the epidermis in order from superficial to deep. For each layer, describe one unique characteristic and name the type of cells found there. Next, make a sentence to help you remember the order of the layers. Use the first letter of the second part of each layer (for example use the letter G for stratum granulosum) since they all start with "stratum." Put together a sentence with 5 words that start with the letters.

Cells of the epidermis are derived from stem cells of the stratum basale. Describe how the cells change as they become integrated into the different layers of the epidermis.2. What structures are produced from keratinization of the epidermis?1.) Epidermis of the skin. Draw the LPO and HPO view of the epidermis and identify its different layers. 2.) Draw an HPO view of the dermis and label its layers/parts. 3.)What are the cell junctions in the stratum spinosum? 4.) Where are the melanocytes located? 5.) Describe the structure and development of the skin and the associated integumentary structures.6.) What are the functions of the integument and its associated structures? 7.) What do all living things have in common? 8.) What kinds of organisms are composed of prokaryotic cells? Eukaryotic cells? What kinds of cells do humans have? 9.) What is tissues?10.) List the four principal tissue types. 11.) Which is true? a. Epithelial tissues are well supplied with blood vessels. b. Connective tissues consist mostly of cells with little extracellular matrix. c. Blood is a connective tissue.
- DIRECTIONS: Match the letter of the description and/or function to the epidermal layer that defines it. A. Outermost layer of dead keratinocytes that protect the skin 6. Stratum basale B. Layer of skin composed of areolar and dense irregular connective tissues 7. Stratum spinosum C. Layer of keratinocytes that undergo apoptosis via keratinization 8. Stratum granulosum D. Single layer of active stem cells that undergo somatic cell division 9. Stratum lucidum E. Layer of skin composed of adipose and areolar connective tissue 10. Stratum corneum F. Layer of keratinocytes with intermediate filaments to resist tension G. Layer of clear, flat, dead keratinocytes found only in thick skinCells of the epidermis derive from stem cells of the stratum basale. Describe how the cells change as they become integrated into the different layers of the epidermis. What determines the color of skin, and what Is the process that darkens skin when it is exposed to UV light?Answer the following questions. What is keratin? Describe the process of keratinization. Identify the 2 layers of the dermis. Describe their locations and the specific type of connective tissue that they are made of. In which layer are melanocytes located? What is their function? Identify all accessory structures located within the dermis. a) List the 2 types of sweat glands found in skin. b) Explain the differences between the 2 types of sweat glands. What type of tissue makes the ducts of the sweat glands? What is the arrector pili muscle? What is its function?
- You are looking at a slide from a patients sole. Which of the following layers of the epidermis would be present in the sample from your patient's sole, but not if you had taken a sample from the skin at their ankle? : Stratum corneum Stratum basale Stratum lucidum Stratum papillum In the "ABCD" rule used while diagnosing melanoma, B stands for: : behavior of the lesion blueness of the lesion border of the lesion blood vessels in the lesionDraw brackets and circles to indicate the layers and structures of the epidermis and dermis in this example of thick skin. Indicate and label the following structures: • Dermal papilla Epidermal ridge Stratum basale Stratum corneum Stratum granulosum Stratum lucidum Stratum spinosumThe human integumentary system is critical for maintaining homeostasis. Identify and describe three distinct structures found in the human skin that aid in the body's homeostasis maintenance.
