    Constant renewing of skin - ProProfs

    Constant renewing of skin

    • Dermis

    • Epidermis

    • Hypodermis

    Correct Answer
    A. Epidermis
    Explanation
    The epidermis is the outermost layer of the skin and is responsible for constant renewing of the skin. It is composed of multiple layers of cells that continuously regenerate and shed, allowing for the growth of new skin cells. This process helps to maintain the integrity and functionality of the skin, protecting the underlying layers and providing a barrier against external factors such as bacteria, UV radiation, and dehydration.

    What is a coloring agent for hair? - ProProfs

    What is a coloring agent for hair?

    Correct Answer
    melanin
    Explanation
    Melanin is a coloring agent for hair. It is a pigment produced by specialized cells called melanocytes, which are located in the hair follicles. Melanin gives hair its natural color, ranging from black to brown to blonde. The amount and type of melanin present in the hair follicles determine the hair color. As we age, the production of melanin decreases, leading to gray or white hair.

    Moistens hair and skin.

    • Apocrine

    • Eccrine

    • Sebaceous

    Correct Answer
    A. Sebaceous
    Explanation
    The correct answer is sebaceous. Sebaceous glands are responsible for producing sebum, an oily substance that helps to moisturize and protect the hair and skin. These glands are found all over the body, except for the palms of the hands and soles of the feet. Sebum helps to keep the hair and skin hydrated and prevents them from drying out.

    • Epidermis

    • Dermis

    • Hypodermis

    Correct Answer
    A. Dermis
    Explanation
    The dermis is the correct answer because it provides elasticity and toughness to the skin. It is the middle layer of the skin, located between the epidermis (outer layer) and the hypodermis (innermost layer). The dermis contains various structures such as blood vessels, nerves, hair follicles, and sweat glands. It is responsible for giving the skin its strength and flexibility, allowing it to stretch and return to its original shape. Additionally, the dermis contains sensory nerve endings that enable us to feel sensations such as touch, pressure, and temperature.

    Blood supply and fat - ProProfs

    Blood supply and fat

    • Hypodermis

    • Dermis

    • Epidermis

    Correct Answer
    A. Hypodermis
    Explanation
    The hypodermis is the layer of skin located below the dermis. It is composed of fat cells and connective tissue, and its main function is to provide insulation and cushioning to the body. The hypodermis also contains blood vessels that supply nutrients and oxygen to the skin and help regulate body temperature. Therefore, the presence of blood supply and fat in the hypodermis makes it the correct answer.

    Only glands found every except palms and soles. - ProProfs

    Only glands found every except palms and soles.

    • Apocrine

    • Eccrine

    • Sebaceous

    Correct Answer
    A. Sebaceous
    Explanation
    Sebaceous glands are the correct answer because they are the only type of glands that are found everywhere on the body except for the palms and soles. Sebaceous glands produce sebum, an oily substance that helps to lubricate the skin and hair. These glands are most plentiful on the face and scalp but can also be found on other parts of the body.

    What is the purpose of the corneum? - ProProfs

    What is the purpose of the corneum?

    Correct Answer
    protection
    Explanation
    The purpose of the corneum is to provide protection. The corneum is the outermost layer of the skin and acts as a barrier against external factors such as bacteria, UV radiation, and chemicals. It helps to prevent water loss from the skin and maintains the skin's hydration levels. Additionally, the corneum also plays a role in preventing the entry of harmful substances into the body. Overall, the corneum serves as a protective shield for the underlying layers of the skin.

    99% water and some salt

    • Eccrine

    • Sebaceous

    • Apocrine

    Correct Answer
    A. Eccrine
    Explanation
    Eccrine glands are responsible for producing sweat, which is composed mainly of water and some salt. These glands are found all over the body and help regulate body temperature by releasing sweat onto the skin's surface. Sebaceous glands, on the other hand, produce oil to lubricate the skin and hair. Apocrine glands are found in areas such as the armpits and groin and produce a thicker sweat that can be broken down by bacteria, causing body odor.

    Coiled tubular sweat glands found in forehead palms and soles. - ProProfs

    Coiled tubular sweat glands found in forehead palms and soles.

    • Apocrine

    • Eccrine

    • Sebaceous

    Correct Answer
    A. Eccrine
    Explanation
    Eccrine sweat glands are the correct answer because they are the coiled tubular sweat glands found in the forehead, palms, and soles. These glands are responsible for producing sweat, which helps regulate body temperature. Unlike apocrine sweat glands, which are found in the armpits and groin and produce a thicker and odorless sweat, eccrine sweat glands produce a watery and odorless sweat. Sebaceous glands, on the other hand, are responsible for producing sebum, an oily substance that lubricates the skin and hair.

    These cells are an extension of the nervous system --- for touch reception. - ProProfs

    These cells are an extension of the nervous system --- for touch reception.

    Correct Answer
    merkel
    Explanation
    Merkel cells are specialized cells found in the skin that are responsible for touch reception. They are considered an extension of the nervous system because they are connected to nerve endings and help transmit sensory information related to touch to the brain. These cells are located in the epidermis, particularly in areas of the skin that are highly sensitive to touch, such as the fingertips and lips. Merkel cells play a crucial role in our ability to perceive and interpret tactile sensations.

    What are the sweat glands whose ducts empty into hair follicles? - ProProfs

    What are the sweat glands whose ducts empty into hair follicles?

    • Apocrine

    • Sebaceous

    • Eccrine

    Correct Answer
    A. Apocrine
    Explanation
    Apocrine sweat glands are the sweat glands whose ducts empty into hair follicles. These glands are found in specific areas of the body, such as the armpits and genital area. Unlike eccrine sweat glands, which are found throughout the body, apocrine glands produce a thicker sweat that contains proteins and fatty acids. This sweat interacts with bacteria on the skin, leading to body odor. The secretion from apocrine glands is triggered by emotional stress or hormonal changes, rather than regulating body temperature like eccrine glands.

    The top layer of dead skin cells. - ProProfs

    The top layer of dead skin cells.

    Correct Answer
    corneum
    Explanation
    The top layer of dead skin cells is called the corneum. This layer acts as a protective barrier for the skin, preventing harmful substances from entering the body and reducing water loss. The corneum is composed of flattened, keratin-filled cells that are constantly being shed and replaced by new cells from the underlying layers of the skin. It plays a crucial role in maintaining the integrity and health of the skin.

    What is a major protein in the hair? - ProProfs

    What is a major protein in the hair?

    Correct Answer
    keratinocyte
    Explanation
    Keratinocyte is a major protein in the hair. Keratin is the main structural component of hair, and keratinocytes are the cells in the hair follicles that produce and secrete keratin. These proteins help to strengthen and protect the hair strands, giving them their structure and elasticity. Keratinocytes also play a role in the growth and regeneration of hair. Therefore, keratinocyte is the correct answer as it is the major protein responsible for the characteristics and health of hair.
