The conversion of living cells into dead protien is called
- A.
Keratinization
- B.
Lucidum
- C.
Mitosis
- D.
Cell devision
Correct Answer
A. KeratinizationExplanation
Keratinization is the process in which living cells are converted into dead protein. This process occurs in the outermost layer of the skin, known as the epidermis. During keratinization, the cells in the epidermis produce a tough, fibrous protein called keratin, which helps to provide protection and waterproofing to the skin. As the cells move towards the surface of the skin, they undergo a series of changes, including the loss of their nucleus and organelles, ultimately becoming flattened and filled with keratin. This process is essential for maintaining the integrity and function of the skin.Rate this question:

- D.
Subcutaneous layer
Correct Answer
A. Stratum germinativiumExplanation
The correct answer is "stratum germinativium." The stratum germinativium is the deepest layer of the epidermis, where melanocytes originate. Melanocytes are responsible for producing melanin, the pigment that gives color to the skin, hair, and eyes. This layer is located above the subcutaneous layer and is responsible for the continuous renewal of the epidermis. The stratum lucidum is a translucent layer found only in thick skin, while the stratum corneum is the outermost layer of the epidermis composed of dead skin cells.Rate this question:

_________ layer of the skin does not contain blood vessels.
- A.
Epidermis
- B.
Corneum
- C.
Dermis
- D.
Cutis
Correct Answer
A. EpidermisExplanation
The epidermis is the outermost layer of the skin and does not contain blood vessels. It is primarily composed of keratinocytes, which are constantly being shed and replaced. The lack of blood vessels in the epidermis is important for the skin's protective function, as it helps to prevent the loss of fluids and nutrients. The dermis, on the other hand, is the layer beneath the epidermis and contains blood vessels, nerves, and other structures. The corneum and cutis are not specific layers of the skin, so they are not relevant to this question.Rate this question:

Correct Answer
A. Subcutaneous layerExplanation
The subcutaneous layer is not a part of the epidermis. The epidermis is the outermost layer of the skin and is composed of several layers, including the stratum corneum, stratum lucidum, and stratum germinativum. The subcutaneous layer, also known as the hypodermis, is located beneath the dermis and is composed of adipose tissue and connective tissue. It serves as a cushioning layer and helps to insulate the body.Rate this question:
