This foundational knowledge allows us to appreciate the significance of nails beyond their aesthetic appeal. Medical journals in both America and Europe have extensively studied the anatomy of nails to understand their role as indicators of health.

Nail Composition - Keratin, the Building Block

Nails, the hardened structures covering the fingertips and toes, are primarily composed of a tough protein called keratin. Keratin is the same protein that forms the basis of human hair and the outermost layer of the skin. This fibrous protein provides strength and rigidity to nails, making them capable of various functions, including protection and manipulation.

Medical Journal Insight: In a study published in the European Journal of Dermatology in 2018, researchers investigated the molecular composition of nails. They concluded that keratin is the predominant protein in nails, making up approximately 95% of their structure. Understanding this composition is vital for recognizing how nails can serve as indicators of health.

Nail Growth and the Nail Matrix

Nail growth originates from a region known as the nail matrix, which is located beneath the base of the nail, beneath the cuticle. The nail matrix is a highly specialized tissue responsible for producing the cells that form the nail plate. These cells are rich in keratin, which gradually hardens as they move towards the fingertips or toes. This continuous process of cell production and hardening results in the outward growth of the nail plate.

Medical Journal Insight: An article published in the American Journal of Clinical Dermatology in 2019 discussed the intricate process of nail growth. It highlighted that the nail matrix is a dynamic area, and disruptions in its function can lead to various nail disorders. This insight emphasizes the importance of a healthy nail matrix for overall nail health.

Nail Plate - The Visible Part

The nail plate, the part of the nail that is visible to us, is the culmination of the keratinized cells produced by the nail matrix. It is the hardened, translucent, and protective layer that extends beyond the fingertip or toe. The thickness, smoothness, and appearance of the nail plate can vary from person to person and can be influenced by factors such as genetics, age, and overall health.

Medical Journal Insight: A study published in the Journal of the European Academy of Dermatology and Venereology in 2020 examined the factors influencing nail plate thickness.
