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.
Understanding the structure of the skin. Our skin is divided into three layers: the epidermis on the surface, the dermis in the middle, and the subcutaneous tissue deepest down. Each layer protects the body in a different way. The epidermis, the uppermost layer of skin, protects us from external irritation. It tends to be very thin, with a thickness of no more than around 0.1-0.3 mm. The epidermis is itself divided into four layers: the stratum corneum, the stratum granulosum, the stratum spinosum, and the stratum basale. Epidermal cells are constantly being created on a 28-day cycle of rebirth and decay. We call this the âturnoverâ of the skin.
