Document Summary
Page 2 of 40: merkel cells, fibroblasts, as skin cells move toward the surface of the body, they produce a protein that reduces water loss. Page 5 of 40: dermatitis, carotene, cyanosis, melanin is produced only by, keratinocytes, basal cells, langerhans cells, d. melanocytes, merkel"s cells, a victim of an automobile accident goes into shock, which results in decreased blood flow. Page 14 of 40: what does structure e represent on the diagram, hair follicle, arrector pili, dermis, hypodermis, sebaceous gland, the figure illustrates keratinization in the epidermis. What layer of the epidermis is d: stratum spinosum, stratum corneum, stratum basale, stratum lucidum, stratum granulosum, the figure illustrates keratinization in the epidermis. Page 15 of 40: apocrine sweat gland, sebaceous gland, eccrine sweat gland, duct of apocrine sweat gland, sweat pore, the diagram illustrates glands of the skin. Vanputte - chapter 05 #10: as skin cells move toward the surface of the body, they produce a protein that reduces water loss.
