The tracks on either side of the nail that the nail moves on as it grows are called the nail folds. These are folds of epithelium at the sides of the nail body, holding it in place.
Understanding the anatomy of the nail and how it grows can help us appreciate the intricate process that occurs right at our fingertips. The nail folds play a crucial role in guiding the growth of the nail and ensuring its stability.
The nail itself originates from the nail matrix at the proximal end, where stem cells divide to form the nail plate or nail body. This nail plate is made up of densely packed dead keratinocytes, giving the nail its strength and structure.
As the nail grows, the edges of the nail plate are embedded in the nail folds. The nail folds act as protective barriers, helping to anchor the nail in place and safeguard the nail margins from damage.
Next time you look at your nails, remember the intricate system of the nail folds that support their growth and health. With proper care and understanding, you can ensure that your nails stay strong and beautiful.
