Cuticle

The cuticle refers to a protective, often hardened, outer layer of a biological structure. It's found in various organisms, playing crucial roles in defense, support, and water retention. In animals, specifically humans, the cuticle often describes the skin fold at the base of fingernails and toenails, acting as a barrier to protect the underlying nail matrix from infection. Plant cuticles, composed of cutin and waxes, are essential for preventing water loss and protecting against pathogens. Insect cuticles, made of chitin, provide an exoskeleton for protection and muscle attachment, whilst microbial cuticles offer a defensive outer layer.
