Stratum Corneum

Question: Briefly explain why skin cancer would not likely originate from cells of the stratum corneum.? Briefly explain why skin cancer would not likely originate from cells of the stratum corneum.

Answer: The cells are all dead in that layer of the epidermis. Dead cells = no mutation = no skin cancer.

Question: Why are there no skin cancers that originate from stratum corneum cells?

Answer: dead cells cannot undergo mitosis let alone cancer, their only job is to form a protective dead layer, and they are shed very easily.

Question: Which is the barrier layer of the skin,is it stratum corneum or stratum lucidium?

Answer: It is the stratum corneum because this skin layer is the outermost layer among other strata and is composed mainly of callus which help to protect skin from abrasions.

Question: Pharmacist can you please give your opinion? Topical appilcations? I'm curious about topical applications or transdermal deliver of topics. I read that it's useless cause the stratum corneum in the epidermis will hinder deliver into the lower layers. Then I wonder about diffusion of what actually reaches through. So do topical applications work? Also is there a delivery agent used to help most topics get past the stratum corneum? If so what is the name?

Answer: Transdermal drug delivery becomes more sophisticated every year. In the 1960's Dimethyl Sulfoxide (DMSO) became used as a vehicle to transport drugs across the skin barrier, but numerous legal, patent, safety and toxicology problems prevented its widespread use. Micro or Nano-emulsions have become the dominant mechanism for transporting drugs across the skin's barrier in the last decade.

Question: The layer of the epidermis that contains cells undergoing division is the? A) a.stratum corneum B) b.stratum lucidum C) c. stratum germinativum D) d.stratum granulosum E) e.stratum spinosum thanks!

Answer: c. stratum germinativum The stratum basale or stratum germinativum (as in germination) is the site of cell replication. The cells mature, then die as they become more superficial.

Question: WHO is knowledgeable about Water Vapor and the Heat Balance between human Skin and the Air ? ? ? The skin is constantly supplied with water to evaporate, the stratum corneum impedes evaporation, but is constantly renewing and adapts to surrounding conditions, especially Humdity, low humidity can damage unacustomed skin (as can high humidity) Who is knowledgeable in this area of cross disipline science with few absolutes ??

Answer: You want a specific book on this subject. I would provide the link but long links don't work correctly on Yahoo Answers. You can get this book at Amazon.com. The book is expensive but is the definitive resource on this topic. I don't believe there is another book that specifically delves into this area of expertise. Measuring the Skin by P. Agache, Philippe Humbert, H.I. Maibach

Question: The layer of dividing cells at the base of the epidermis is the? A) stratum corneum B) stratum lucidum C) stratum germinativum D) stratum granulosum E) stratum spinosum

Answer: c). stratum germinativum

Question: The layer of the epidermis that contains melanocytes is the? A) a.stratum corneum B) b.stratum lucidum C) c.stratum germinativum D) d.stratum granulosum E) e.stratum spinosum

Answer: Remembering from my anatomy class it is in the stratum basale, but that isn't an option. So I looked it up on wikipedia and sure enough it is in the stratum basale. So after looking up stratum germinativum that is stratum basale so answer C is correct. It is the deepest layer of the epidermis.

Question: which of the follwoing does not containe keratinized cells? which of following does not containe keratinized cells a. dermal papillae b. stratum corneum c. hair d. nails

Answer: hair and nails do for sure, I learned this in my biology class.. and stratum corneum does too, I'm pretty sure. "The stratum corneum is the outermost layer of the epidermis, composed of large, flat, polyhedral, plate-like envelopes filled with keratin, which is made up of dead cells that have migrated up from the stratum granulosum." Therefore the answer is a. Hope this helped! :)

Question: Any dermatologists out there? How long does it take for a skin cell to travel from the stratum basale to the stratum corneum? Does anyone know or know where I can find this information?

Answer: 28 days
