The term 'onychosisis' specifically refers to any deformity or disease affecting the natural nail. This encompasses a variety of conditions that can alter the appearance, texture, or health of the nail plate. By understanding 'onychosisis' in this way, it becomes clear that this term is a clinical descriptor used in the field of dermatology and cosmetology to identify issues related to the nails, such as lifting, discoloration, or structural abnormalities resulting from injury or disease.

In contrast, the other options address different topics unrelated to the definition of 'onychosisis.' The health of the surrounding skin pertains to skin conditions rather than to the nail itself, while the appearance of artificial nails deals with enhancements that do not relate to the natural nail's health or structure. The process of nail growth is a biological function, which is also distinct from the definition of 'onychosisis,' as it does not describe a deformity or disease but rather the natural cycle of nail formation.
