To become a pediatric nurse, you must complete additional training beyond what is required to be licensed as a Registered Nurse (RN) and may choose to earn the Certified Pediatric Nurse (CPN) credential. Educate patientsâ families and caregivers about procedures, treatments and other types of medical care.
Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
In humans and other mammals, the skin has three parts-the epidermis, the dermis and the subcutis (or hypodermis). The epidermis forms the surface of the skin. It is made up of several layers of cells called keratinocytes.The dermis lies underneath the epidermis and contains skin appendages: hair follicles, sebaceous (oil) glands and sweat glands.The subcutis contains fat cells and some sweat glands. Melanocyte stem cells are responsible for regeneration of melanocytes, a type of pigment cell. 2  Melanocytes produce the pigment melanin, and therefore play an important role in skin and hair follicle pigmentation. 3  It is not yet certain where these stem cells are found in humans.
