In human anatomy, the “epidermis” may refer to several structures, but it is used in colloquial language, and even by doctors, when talking with patients to refer to the thickened skin surrounding nails and nails of the feet (eponychium) and refer to the external part of the hair, consisting of dead cells.  It can also be used as a synonym of the epidermis of the outer layer of the skin and the surface layer of overlapping cells covering the hair shaft (cuticula pili), which closes the hair in its follicle.

Cuticle function

The main structural components of plant skins are the unique cutin and/or cutan polymers impregnated with wax. Plant skins act as barriers of permeability to water and water-soluble materials.


In Cuticle function, the skin protects both the plant surfaces from getting wet and prevents the plants from drying out. Xerophytic plants, such as cactus, have very thick skins that help them survive in a dry climate. Plants that live in a sea spray may also have thicker shells that protect them from the toxic effects of salt.


Some plants especially adapted to live in a moist or aqueous environment, have extreme resistance to wetting. A well-known example is Sacred Lotus. This adaptation is not only a physical and chemical effect of the wax coating but depends to a large extent on the microscopic shape of the surface.


When the hydrophobic surface is sculpted into microscopic, regular, elevated areas, sometimes in fractal patterns, too high and too close to each other so that the surface tension of the liquid allows any flow into the space between the plateaus, then the contact area between the liquid and solid surfaces can be reduced to a small fraction of what a continuous surface can allow. The result is a significant wetting of the surface.



Mycology Cuticle


“Peel” is one term used in reference to the outer layer of the basidiocarp tissue of the fungus or “fruit”. The alternative term “pileipellis”, Latin “skin” “cap” (which means “mushroom”)  may be technically preferred, but it may be too cumbersome for widespread use. This is the part removed during the “peeling” of the mushrooms.


On the other hand, some morphological terms in mycology make smaller distinctions, such as those described in the article on the topic of “pileipellis”. Irrespective of this, the bristle (or “skin”) differs from the trama, the internal meaty tissue of the fungus or similar fruiting body, and also from the tissue layer of spores, hymen.[post_grid id=”473″]
