horny layer การใช้

:Skin is made up of layers of cells covered with a ( relatively ) thick, horny layer of keratin.
Males also have a strong pad on the inner side of the first finger, covered during the breeding season with a greyish brown velvet-like horny layer.
These effects include removing fat emulsion, defatting of dermal lipids, inflicting cellular damage on the epithelium, and increasing the transepidermal water loss by damaging the horny layer water-binding mechanisms and damaging the DNA, which causes the layer to thin.
The horny layer in this form is not produced in the normal manner, remaining too moist and not sufficiently greasy, thus constituting a "'stiff and brittle "'covering, rather than the supple, water-proof, normal surface . . ."
