Final answer:
Manicuring is a non-invasive cosmetic procedure focused on the care of human nails, cuticles, and calluses, which are part of the integumentary system. Nails consist of dead cells, with the free margin being the portion trimmed during a manicure. Cutting the cuticle is discouraged as it provides a protective seal against infections.
Step-by-step explanation:
The terminology used at s. 454.01 (13) Stats refers to the practice of manicuring, which is a specific aspect of personal care within the field of cosmetology focusing primarily on the maintenance and appearance of the nails. As the body of knowledge around nail care has evolved, so too have the practices and regulations that govern this niche area. The cutting of human nails, cuticles, and calluses constitutes the bulk of manicure services and does not include any other invasive procedures, ensuring a clear boundary within the professional scope.
Nails are important accessory structures of the integumentary system, consisting of layers of hardened keratinocytes, and appear to be a continuation of the skin. The free margin of the nail is the part that extends over the fingertip which is commonly trimmed or filed during a manicure to keep the nails tidy. The cuticle is a layer of dead epithelial cells that functions as a protective barrier, sealing the edges of the nail plate to the skin and preventing underlying tissue infections. Therefore, the practice of cutting the cuticle is generally discouraged in manicures to avoid compromising this protective seal.
The nail plate of the human nail is primarily made up of dead cells, similar to the hair shaft, which is why it does not bleed when it is cut. Routine nail care, such as trimming the free margin or gently pushing back the cuticle, can be beneficial to nail health when performed properly. It is important to understand the function and composition of the different parts of the nail when practicing or seeking nail care services.
