Where are keratinized cells found in the body?
A. Sweat and sebaceous glands
B. Hair and nails
C. Capillaries and nerve fibers
D. The subcutaneous layer of the skin
i think d
To the extent of my knowledge.
B is the correct answer.
In addition to my first answer.
Here is a GOOGLE search on the subject.
During development, the embryo contains keratinized cells in a number of places. One unique spot is in the lining of the esophagus, which is normally not keratinized in adults. In adults, keratinized cells form the topmost layer of the skin (the stratum corneum of the epidermis).
thanks!
To find the answer to this question, we need to have an understanding of what keratinized cells are and where they are commonly found in the body.
Keratinized cells are cells that have undergone a process called keratinization, wherein they become filled with a protein called keratin, making them tough and resistant to external damage. These cells are typically found in structures that require protection and durability.
Now, let's go through each option and see which one includes structures that contain keratinized cells:
A. Sweat and sebaceous glands: Sweat glands produce sweat, while sebaceous glands secrete sebum, an oily substance that helps lubricate the skin and hair. Neither of these glands contains keratinized cells, so we can eliminate this option.
B. Hair and nails: Both hair and nails are composed of keratinized cells. This means that they have undergone the process of keratinization, making them strong and resilient. So, this option is a probable answer.
C. Capillaries and nerve fibers: Capillaries are tiny blood vessels, and nerve fibers are part of the nervous system. Neither of these structures contains keratinized cells, so we can eliminate this option.
D. The subcutaneous layer of the skin: The subcutaneous layer, or the hypodermis, is the deepest layer of the skin. It consists of connective tissue and fat cells, but it does not contain keratinized cells. Therefore, we can eliminate this option.
Based on the information provided, option B, which includes hair and nails, is the correct answer.
