2. The narrow strip of thickened epidermis at the base of a fingernail or toenail.
3. The sheath of a hair follicle.

cuticle

  1. in both animals and plants, a thin noncellular layer secreted by the epidermis. In higher plants it covers all the exterior, except where stomata and lenticels occur, and prevents water loss (cuticularization). In many arthropods, it forms part of the EXOSKELETON and is composed of CHITIN and PROTEIN, with a calcareous element in CRUSTACEANS.
  2. the epidermal cells of vertebrates (the stratum corneum) that have been converted to KERATIN (as in hair, feathers, scales, nails, claws, hooves, horns, etc.), giving proofing against water loss, bacterial entry and ultraviolet light.

n the outer layer of the skin. Also, a layer that covers the free surface of an epithelial cell.
cuticle, primary,
n 1. the transitory remnants of the enamel organ and oral epithelium covering the enamel of a tooth after eruption.
Synonym: Nasmyth's membrane. 2. is believed to be the last substance formed by ameloblasts, mediating the attachment of ameloblasts to the enamel.
cuticle, secondary,
n 1. the second cuticle formed when the ameloblasts are replaced by the oral epithelium. It then covers the primary cuticle on the enamel and is the only cuticle on the cementum.
2. a keratinized pedicle found between the gingival epithelium and the surface of a tooth.

cuticle

1. a layer of more or less solid substance covering the free surface of an epithelial cell.
2. the narrow band of epidermis extending from the wall of the nail or claw, onto the surface; called also eponychium.
3. the layer of cells on the surface of a hair shaft or wool fiber. In wool it is the projection of the edge of cuticular plates that gives the fiber its unique felting property.
4. an extremely thin, transparent, proteinaceous covering over the eggshell of bird's eggs. It may contain pigment and is permeable to gases.

cuticle of koilin
a tough membrane, usually greenish, and a carbohydrate-protein complex, produced by the solidification of the secretion of the tubular glands in the gizzard mucosa of birds; the cuticle protects the mucosa during its crushing operations.

Hypotheses have been proposed, including that BPUs interfere with the formation of the cuticle due to an increase in chitinase activity (Ishaaya & Casida 1974, Merzendorfer & Zimoch 2003) or that of the chitin by activation of the proteolytic activity of chitin synthase (Leighton et al.
