Uncovering The Mystery: How Your Nails Protect And Support Your Fingers

how do finger nails work

Fingernails are an important part of the body, providing protection for the tips of fingers and toes and helping with fine motor functions. They are made of keratin, the same substance that hair and the top layer of skin are made of. The nail plate is mostly made of keratin and is about half a millimeter thick.

Nails protect the tips of fingers and toes

Fingernails and toenails are made from skin cells, hair is also a skin appendage. The nail plate is mostly made of a hard substance called keratin and is about half a millimeter thick and slightly curved. The nail is firmly attached to the nail bed beneath it and separates at the tip of the finger or toe, where the end of the nail sticks out. This allows us to use our nails as tools, for example, scratching.

The hyponychium (informally known as the "quick") is the epithelium located beneath the nail plate at the junction between the free edge and the skin of the fingertip. It forms a seal that protects the nail bed. The onychodermal band is the seal between the nail plate and the hyponychium.

The hard surface of your nails helps to protect the tips of your fingers and toes. The tops of the toes are vulnerable to injury and stubbing.

Fingernails provide good clues to a person's overall health. For instance, when the doctor presses your nails, he or she is checking your blood circulation. By looking at your nails, a doctor may find changes that may be associated with skin problems, lung disease, anemia, and other medical conditions.

There’s an intricate network of nerves underneath the nail. While a person doesn’t have to have fingernails to survive, they can certainly help with many tasks. Can you imagine if your fingertips tried to roll backward when you held something? The strength and existence of fingernails helps keep this from happening (thank goodness!). The main function of toenails is likely for protection, compared to enhancing grip or the fine motor functions the fingernails have. The tops of the toes are vulnerable to injury and, as we’ve all learned the hard way, stubbing.

Don't be surprised if your doctor takes a look at your nails at your next checkup, even if you're having no problems with them. Fingernails provide good clues to a person's overall health.

Nails provide clues to overall health

Fingernails and toenails are made from skin cells, which are called skin appendages. Hairs are also skin appendages. The part that we call the nail is technically known as the “nail plate”.
