Learn stratum corneum with free interactive flashcards. The stratum corneum (Latin for 'horny layer') is the outermost layer of the epidermis.There has been a long-standing belief in dermatology that the stratum corneum consisted of dead cells (corneocytes), devoid of biological activity and function.The stratum corneum is now understood to be live tissue that performs protective and adaptive physiological functions including … The thickness of the integumentary system ranges between 1.5 and 4 inches. The epidermis is rich in blood vessels and nerves. Functions: water repellant, protect from injury and microbial invasion.Only Present in THICK skin. deepest epidermal layer, has STRATUM GERMINATIVUM (melanocytes, langerhans cells, merkel cells, tactile discs) Stratum Spinosum. Lamellar granules (water repellant)25- 30 layers flattened dead keratinocytes. innermost epidermal layer; aslo called stratum basale.

The stratum corneum is a layer within the epidermis, the outermost layer of our skin. Overcleansing, using harsh exfoliants, and rubbing skin can strip the outer layer of skin of natural lipids and … True. Active in puberty, stimutaled by androgens (hormones).1.
Separates the stratum germinativum The process occurs on all exposed skin surfaces except the anterior surfaces of the eyes.water from interstitial fluids slowly penetrates the surface, to be evaporated into the surrounding air causing you to loose roughly 500 ml of water.
