Küünepõhi

Küünepõhi, also known as the nail bed, is the area of skin beneath the fingernail or toenail. It is a vital part of the nail apparatus, providing support and nourishment for the growing nail plate. The nail bed is composed of specialized epidermal cells that are tightly attached to the underlying dermis. This connection is crucial for the strength and integrity of the nail.

The color of the nail bed contributes significantly to the appearance of the nail. A healthy nail bed typically has a pinkish hue due to the rich blood supply in the underlying dermis. This blood flow is essential for delivering nutrients and oxygen to the cells responsible for nail growth. Any changes in the color of the nail bed can indicate underlying health issues. For instance, a pale or white nail bed might suggest anemia, while a bluish tint could be a sign of poor circulation or respiratory problems.

The nail bed also plays a role in sensation. It contains numerous nerve endings that allow us to perceive touch and pressure. This sensitivity helps protect our fingertips and toes from injury. Conditions affecting the nail bed, such as infections or trauma, can lead to pain, inflammation, and alterations in nail growth. Proper care of the nail bed, including keeping it clean and moisturized, is important for maintaining healthy nails and preventing potential complications.
