The snout is very blunt, with the lower jaw's plate ( which consists of cornified epithelium ) jutting out slightly.
12.
Keratin 13 is a type I cytokeratin, it is paired with keratin 4 and found in the suprabasal layers of non-cornified stratified epithelia.
13.
Colonies of dematophytes are usually restricted to the nonliving cornified layer of the epidermis because of their inability to penetrate viable tissue of an immunocompetent host.
14.
These hard, integumentary structures are formed by intercellular cementing of fibers formed from the dead, cornified cells generated by specialized beds deep within the skin.
15.
The skin of crocodilians is thick and cornified, and is clad in non-overlapping scales known as scutes, arranged in regular rows and patterns.
16.
The tail was also unusual in that the free part resembled the shape of a feather, with the large cornified scales a prominent feature on the underside.
17.
These proteins are highly insoluble and extensively cross-linked to each other, giving the insoluble property of the cornified envelope and contribute to the mechanical resistance of the skin.
18.
TG5 is strongly expressed in the epidermal granular cells, where it cross-links a variety of structural proteins in the terminal differentiation of the epidermis to form the cornified cell envelope.
19.
These skin cells finally become the cornified layer ( " stratum corneum " ), the outermost epidermal layer, where the cells become flattened sacks with their nuclei located at one end of the cell.
20.
Its thickness varies between 15 and 20 nm ., and is formed during the transition stage of granular keratinocytes into corneocytes The three proteins that form the scaffold of the cornified envelope include involucrin, envoplakin and periplakin.
