Study Notes
Structures of Nail
- Lunula: A crescent-shaped, pearly area indicating densely packed cells; blood capillaries are not visible.
- Cuticle: Overlapping skin at the nail base, the 'true cuticle' is often removed during manicuring.
- Free Edge: The protruding part of the nail that can be shaped and filed, extending over the hyponychium.
- Matrix: Living part of the nail located beneath the cuticle; responsible for nail growth by producing new cells. Damaged matrix can lead to deformed nails.
- Nail Bed: The area where the nail plate rests; rich in blood vessels and nerves, featuring grooves that match the nail plate's underside.
- Nail Walls: Skin folds that protect the edges of the nail and anchor it in place.
- Nail Plate: The visible portion of the nail, mainly composed of dead cells; semi-transparent due to underlying blood circulation.
Shapes of Nail
- Oval Nail: Suited for long nail beds; slightly rounded at the base and pointed at the tip; has a natural appearance.
- Round Nail: Suitable for short nails, where 1.5 mm sides are grown out straight before being rounded; offers strength.
- Stiletto/Pointed Nail: Tapered to a point; lacks strength due to loss of side support.
- Squoval: Combines an oval shape with a squared tip for added strength.
- Square Nail: Grows straight out with a flat tip cut across at right angles, maintaining the plate's line.
Nail Diseases and Disorders
- Nail conditions arise from infections (bacterial, fungal, viral) affecting both nails and surrounding skin.
- Infections may present as green, yellow, or black discoloration; often linked to damaged cuticles or broken skin.
Nail Disorders
- Blue Nails: Characterized by a bluish tint, often indicative of poor blood circulation or heart issues.
- Brittle Nails: Marked by vertical splitting or separation at the free edge, commonly caused by exposure to harsh detergents.
