stratum basale: youngest karatincytes made by stem cells.
Cells found in Stratum Granulosum of Epidermis of skin, and these cells are basophil and suspected to play role in keratinization.
Keratinization starts when protein in the form of food is digested and the body breaks it down into amino acids. These enter the blood stream and are carried to the papilla and the matrix at the base of the follicle where cells are formed that will eventually create hair.
C. E. Orfanos has written: 'Feinstrukturelle Morphologie und Histopathologie der verhornenden Epidermis' -- subject(s): Diseases, Epidermis, Keratinization, Skin
the addition of keratin to the stratified squamous epithelial cells in the epidermis. Begins in the stratum spinosum and continues into the stratum granulosum.
Formation of keratin protein in cell is called keratinization .
Just took a quiz on this.. the answer is.. Keratinization is the result of Vitamin A deficiency
Dead Epidermis refers to dead upper skin layers in humans and animals. The skin has two layers, the Epidermis (which is on the very surface) and the much thicker Dermis, which lies below and forms the main body of skin. Every so often, parts of the epidermis die and flake off, to be replaced by a new one that grows to take it's place. This is to keep the skin clean, and get rid of harmful bacteria that get trapped in the Epidermis.
Acually, they only partially have one. You see, they have an inner epidermis, but not an outer one. The epidermis acually was not the purpose to protect the plant in the first place!
The basal layer, also called the stratum germinativum is the most active part of the epidermis and the place where new cell growth takes place.
They produce nails :)
Skin is respomsible for covering and holding the skelton in place
