Skin, nails, hair | Nursing homework help
Important parts of the body, such as hair and skin, perform important functions. Skin, hair and nails are affected by a number of physiological factors, which can lead to abnormalities. Jensen (2005) states that the skin is composed of three layers, including the dermis and the subcutaneous tissues. The epidermis, the topmost layer of skin, contains melanocytes that produce the melanin responsible for skin colour. Dermis is composed of sweat glands and sebaceous follicles. Subcutaneous tissue is composed of fat, connective tissues, and large blood vessels.
Hair and nails have similar structure. Hair grows in hair follicles found within the subcutaneous and dermal tissue. Hair shafts are made up of three layers, the cortex, cuticle and medulla. Hair variations can be caused by genetics, hormone changes and illnesses such as Alopecia. Problems with nails can be caused by systemic illnesses, infections, trauma or medication. Some common nail issues include ridges and ingrown or fungal nails.
Skin, hair and nails are affected by a number of physiological factors. Variations of these factors may cause problems and abnormalities. To accurately assess patients and give them appropriate care, nurses should have a thorough understanding of these variations and factors. Nurses should also educate their patients about proper nail, skin, and hair care in order to promote health and prevent issues.
