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.
The epidermis is the main component of the dermal tissue system of leaves (diagrammed below), and also stems, roots, flowers, fruits, and seeds; it is usually transparent (epidermal cells have fewer chloroplasts or lack them completely, except for the guard cells.) The cells of the epidermis are structurally and functionally variable.
