Nails - are complex structures located at the distal ends of fingers and toes, serving both protective and functional roles.
Nail - They are primarily composed of keratin, a tough and fibrous protein that is also found in hair and the outer layer of skin.
NailPlate - The visible part of the nail, the nail plate is a hard, keratinized structure that serves as a protective barrier. It is the part of the nail that is commonly polished and groomed.
NailBed - The nail bed is the skin beneath the nail plate. It is rich in blood vessels and nerves, providing nutrients to the nail plate and contributing to its pinkish color.
Nail Matrix - Located beneath the cuticle at the base of the nail, the nail matrix is responsible for producing new cells that make up the nail plate. It is the growth center of the nail.
Lunula - is the whitish, crescent-shaped area at the base of the nail. It is part of the nail matrix and is more visible on some nails than others.
Cuticle - also known as "Eponychium", is a thin layer of skin at the base of the nail that protects the nail matrix from infection by sealing the space between the nail plate and the skin.
Hyponychium - is the area of skin just under the free edge of the nail. It acts as a barrier to prevent pathogens from entering the nail bed
Free Edge - is the part of the nail plate that extends beyond the fingertip. It can be trimmed and shaped for cosmetic purposes.
Protection - They protect the sensitive tips of fingers and toes from mechanical injury and environmental damage.
Sensory Enhancement - Nails provide a counterforce to the fingertips, enhancing the sense of touch and aiding in the manipulation of small objects.
Support - Nails offer structural support to the fingertips, allowing for precise movements and improved grip.
Indicators of Health - Changes in nail color, texture, or shape can indicate underlying health conditions, such as nutritional deficiencies, infections, or systemic diseases.
Protection - 1st physiological function of the nail
Sensory enhancement - 2nd physiological function of the nail
support - 3rd physiological function of the nail
indicators of health - 4th physiological function of the nail
