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 skin (integument) and its derivatives (adnexa) comprise the largest organ in the body. Skin is composed of two layers: (1) the ectodermally derived surface layer called the epidermis and (2) the underlying mesodermally derived connective tissue layer which is called the dermis. The epidermis is a stratified squamous epithelium with a different number of cell layers in different areas of skin.
