Question

The second layer of epidermis in rat integument is?
A) Stratum lucidum
B) Stratum germinations
C) Stratum corneum
D) Dermis
E) Stratum granulosum

Answer 1

Hint:The second layer below the epidermis is the dermis, which contains collagen, elastin, blood vessels and hair follicles. The sweat glands in this layer produce sweat, which helps to remove toxins from the body and keep the body cool.

Complete answer:
>Stratum granulosum: The cells of the granular layer (SGR) accumulate dense basophilic corneal hyaluronic acid particles (visible in close-up view). These particles contain lipids and are linked to liposomes to help form a waterproof barrier to prevent water loss from the body.
>Stratum germinations: The basal layer (the basal layer, sometimes called the germination layer) is the deepest of the five layers of the epidermis and is the outer surface layer of mammalian skin. The basal layer is a single layer of columnar or cubic basal cells.
>Stratum corneum: The stratum corneum is the outermost layer of the epidermis, and is made up of ten to thirty thin layers of continually shedding, dead keratinocytes. The stratum corneum is also known as the "horny layer," because its cells are toughened like an animal's horn.
>Stratum lucidum: The transparent layer is responsible for the stretch ability of the skin. It also contains proteins responsible for the degeneration of skin cells. This thick layer also reduces the effects of skin friction, especially in areas such as soles and palms.

Thus, the correct answer is option (A).

Note:The skin is the largest organ of the human body there are two main epidermal layers (Outer layer) and dermis (inner layer). The epidermis has several layers or layers. The deepest formation is the Basale layer, this is a single-layer cube or columnar cell.
