In the stratum corneum, another layer of the epidermis, the keratinocyte gradually migrates to the surface and is sloughed off in a process called desquamation. The dermis (corium) is a complex network of collagen fibres, sweat glands, hair roots, nervous cells, nervous fibres and blood ...
The stratum corneum is the outermost layer and is 20-30 cells thick, made of deadkeratinized cells. The stratum lucidum, usually only found in the palms and bottom of feet, reduces friction. The stratum granulosum is composed of tightly compacted, flattened cells that help waterproof the skin...
A poloxamer 407 (POX) gel containing dimethyl isosorbide (DMIS), isopropyl alcohol (IPA), propylene glycol dicaprylocaprate (MIG) and water has been suggested in a previous study for permeation enhancement of 5-aminolevulinic acid (ALA) across isolated human stratum corneum. The purpose of this...
Nails are homologous to the stratum corneum of the epidermis and contain a variety of minerals, such as calcium. They consist of compacted and layered keratin-filled squames (scales). The arrangement and cohesion of the squames are responsible for the hardness of nails. A nail consists of: ...
Cutaneous water loss and sphingolipids in the stratum corneum of house sparrows, Passer domesticus L., from desert and mesic environments as determined by ... Because cutaneous water loss (CWL) represents half of total water loss in birds, selection to reduce CWL may be strong in desert birds...
