A type of keratinocyte, the stratum granulosum - which is comprised of one to three layers of flattened cells - produces kerato-hyalin, present as small granules.

What is major factor accounting for the waterproof nature of skin?
Glycolipid (lamellated granules) between stratum corneum cells.These granules accumulate in the keratinocytes of the stratum granulosum, and contain a waterproof glycolipid that is excreted into extracellular space helping to slow water loss across the epidermis.
What does not belong waterproof elastin lamellated granules produced by keratinocytes?
Lamellated granules, the rest are proteins or produce proteins found in the skin.
What pigment is phagocytized by keratinocytes?
Melanocytes phagocytize melanin. First, melanocytes which are present in the lowest or basal layer of the epidermis, produce the pigment melanin. The melanin forms granules called melanosomes. After the keratinocytes take up the pigment, it clusters around the keratinocyte nucleus on the superficial side. This protects the DNA in the keratinocyte nucleus from damage due to UV radiation.
Melanocytes and keratinocytes work together in protecting the skin from the UV damage when keratinocytes?
Accumulate the melanin granules on their superficial portion, forming a pigment that protects DNA from UV radiation
What is cytocrine secretion?
Injection of secretory granules into neighboring cells Such as melanocytes injecting melanosomes to neighboring keratinocytes
In which layer of the epidermis are granules of keratohyalin formed?
stratum granulosum
Where are lamellar granules produced?
in the the stratum granulosum cells of the epidermis.
What are the steps to extrusion moulding?
Thermoplastic granules are added into a hopper, these granules fall into a Archimedes Screw and are push towards a steel dye. The hydraulic ram at the base of the screw forces the screw forwards to make sure all of the plastic has been extruded. At the end of the process you are left with a shape of a continuous cross section e.g. a pipe.
What is the advantage for melanin granules being located in the deep layer of the epidermis?
The melanin is used to protect the cell's nucleus from the UV radiation from the sun. Since the upper layers of the skin are dead, there either is no nucleus remaining, or there simply is no need to protect the nucleus, therefore melanin granules are needed only in the deeper layers of skin
What is granules is sugar is a granules?
The size of the granules differ depending on what kind of sugar you are talking about. www.joyofbaking.com/sugar.html
Why the sugar granules is sample of matter What is the reason?
sugar granules is the sample matter
How are plastic granules made?
From recycled plastic granules
