To understand what a nail bed is, it is best to first have an idea of the function and anatomy of the entire nail. The nail is made up of several parts. There is the cuticle, which holds the nail to the finger; the nail plate, which is the main part of the nail; and the usually crescent-shaped lunula, or nail root, located near the cuticle. The parts around the nail include the perionychium, which is located on the sides of the nail, where toenails and ingrown nails occur, and the hyponychium, which is located under the front of the nail plate, where the skin connects to the finger. The nail bed, also known as the nail bed, is located under the nail plate.
The general function of a nail is to protect our fingers, as well as help us feel what we touch with more sensation. Each part of the nail is important in its own way. The nail bed is responsible for the development of the nail plate. Cells found in the nail bed produce keratin, which builds up in layers and becomes the hard nail plates found on our fingers and toes.
Nails can also reveal certain aspects of our health. If a nail bed is injured, the nail may develop white spots, although these spots usually diminish over time. Some indications may be more serious. For example, a symptom of inflammatory skin psoriasis is the separation of the nail plate from the nail bed. This same symptom can also be caused by a response to certain medications.
People with diabetes should be especially cautious of any nail injuries or nail bed infections. As with any potential medical condition, a medical exam should be scheduled to confirm a diagnosis and continue treatment. Signs of a nail bed infection include redness, swelling, pressure, and a feeling of warmth or burning in or around the nail.
Although not all nail bed problems are preventable, there are certain steps that can be taken to help protect them from damage and infection. Habits such as nail biting and chewing should be avoided as they can directly damage the nail bed and allow bacteria to enter the nail. Nail polish remover should be used sparingly as it tends to dry out the nail, which can lead to splitting of the nail and the introduction of bacteria.
Using a nail hardener is a good way to help build the strength of the entire nail. This will also protect the nail bed. Healthy nail beds help keep the entire nail intact and smooth, resulting in a nice-looking nail and better finger feel and dexterity.
