What is the function of Eleidin?

Eleidin is a transformation product of the amino acid complex keratohyalin, the lifeless matter deposited in the form of minute granules within the protoplasm of living cells. Eleidin is then converted to keratin in the stratum corneum.

What do Keratohyalin granules do?

Keratohyalin granules are important in the formation of the protective skin barrier and the terminal differentiation of the epidermis. FLG is associated with keratin intermediate filaments in the outer granular layer of the epidermis, and it supports their packing into bundles.

What do Keratohyalin granules contain?

Keratohyalin granules (KHG) mainly consist of keratin, profilaggrin, loricrin and trichohyalin proteins which contribute to cornification or keratinization, the process of the formation of epidermal cornified cell envelope.

What is the clear layer?

The stratum lucidum (Latin, ‘clear layer’) is a thin, clear layer of dead skin cells in the epidermis named for its translucent appearance under a microscope. It is readily visible by light microscopy only in areas of thick skin, which are found on the palms of the hands and the soles of the feet.

What are lamellar granules?

Lamellar granules (LG), also known as keratinosomes, lamellar bodies, membrane-coating granules, and Odland bodies, are specialized secretory granules of the keratinizing stratified squamous epithelia and are thought to be essential in barrier formation and desquamation (Hayward, 1979;Odland and Holbrook, 1981).

What do Tonofilaments do?

tonofilament. A bundle of intermediate filaments within a cell. They bind the pieces of the cytoskeleton to each other and to the cell membrane.

Which of the following is the red yellow form of melanin?

The more common product is eumelanin (brown) but in the presence of cysteine, pheomelanin can be formed (red to yellow). Melanin is formed primarily in the melanocyte, located in the inner layers of the skin where melanin and carotene blend to produce the skin color as well as the color in the eyes and hair.

What is Hyperkeratinization of the skin?

Follicular hyperkeratinization (abnormally rapid shedding of skin cells) in the sebaceous gland and follicular infundibulum (uppermost section of the hair follicle, near the opening of the pores) can be considered one of the crucial events in the development of acne lesions.
