Final answer:
The cuticle provides a protective barrier for the nail matrix, preventing bacteria and infection. Composed of a layer of dead epithelial cells, it seals the edge of the nail plate and protects the matrix where nail growth originates.
Step-by-step explanation:
The structure acting as a barrier to stop bacteria and infection from getting to the nail matrix is known as the cuticle. The cuticle is a layer of dead epithelial cells that overlaps and seals the edge of the nail plate. The nail itself is a composition of dead keratinocytes filled with keratin, which makes them tough yet flexible. The nail matrix is a deep layer of epidermal tissue located at the proximal end of a nail, and it is where nail growth occurs. Stem cells within the matrix divide to allow the nail to grow, forming the nail root and then the nail plate as the nail extends outward. The cuticle functions to protect the nail matrix by preventing pathogens such as bacteria from infiltrating and creating infections, which could disrupt nail growth and the health of the nail bed.
It’s important to keep your cuticles clean at home. This prevents infection.The easiest way to care for them is to soak your hand or foot in soapy, warm water for around 10 minutes every few days. This helps soften the cuticle and keeps your nails clean.
You can also apply cuticle oil and a massage cream. Moisturize your cuticles regularly to prevent dryness and cracking.
