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.
1 Epidermis is the single exterior layer that protects the stems, leaves, flowers, and roots. 2  The outside surface of the epidermis tissue is usually covered with a waxy substance called cutin, which reduces water loss. 3  Parenchyma tissues are made of simple, thin-walled cells.
