¶ … tissue types that compose the epidermis. Name the tissue types that compose the dermis. List the major layers of the epidermis and dermis and briefly describe the individual functions of each layer.

The epidermis of skin is composed of 4 cell types, which may be stratified or squamous: keratinocytes, melanocytes, Merkel's cells, and Langerhan's cells. The dermis is the layer of skin beneath the epidermis, which consists of three major constituents: collagen, elastic fibers, and reticular fibers. The epidermis layer can have up to five strata while the dermal layer has two. Together, from the outermost to innermost, these strata are: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale in the epidermis, and the papillary and reticular layer in the dermis.

The functions of these layers are as follows:

Stratum corneum -- composed of dead cells and keratin, prevents desiccation of deeper cells

Stratum lucidum -- composed of dead, flattened keratinocytes and also melanocytes, contains high levels of melanin and helps protect against UV damage

Stratum granulosum -- layer where keratinocytes initiate keratinization and begin producing keratin

Stratum spinosum -- keratinization may also initiate at this stratum, contains spiny cells which interlock, providing additional structure to skin

Stratum basale -- continuously dividing layer of keratinocytes, basement of epidermal layer, typically one cell thick

3. Name the three pigments that contribute to skin color. Give a brief example of how a specific change in skin color could be used as a clinical sign for certain pathologies.

Research Proposal on Tissue Types That Compose the Epidermis. Name Assignment

Skin color is produced by three elements: melanin (pheomelanin or eumelanin), hemoglobin, and oxyhemoglobin. Hypoxia is an example of a condition where skin color is altered by a decrease in oxygenated hemoglobin. Lack of oxygen results in dark red hemoglobin (deoxyhemoglobin), which when seen through the skin appears blue. Thus, people who are experiencing pathological hypoxia may manifest blue skin.

4. In clinical practice, drugs can be delivered by… [END OF PREVIEW] . . . READ MORE
