    What are the 3 functions of skin?

    • Protection

    • Temperature

    • Make us look good

    • Sense organ

    Correct Answer(s)
    A. Protection
    A. Temperature
    A. Sense organ
    Explanation
    The skin has three main functions. Firstly, it acts as a protective barrier, shielding our internal organs and tissues from harmful external factors such as bacteria, UV radiation, and physical injuries. Secondly, the skin helps regulate body temperature by controlling the loss or retention of heat through sweat production and blood flow. Lastly, the skin is also a sense organ, providing us with the ability to perceive touch, pressure, pain, and temperature through specialized nerve receptors.

    When new cells are made, they begin to move toward the surface.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The statement suggests that when new cells are produced, they start migrating towards the surface. This is a true statement as cells in various tissues and organs undergo a process called cell differentiation, where newly formed cells move and mature towards the outer layers or surfaces of the tissue or organ. This movement is essential for the growth, development, and maintenance of tissues and organs in the body.

  • 4. 

    Apocrine glands become active during puberty.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    During puberty, the body undergoes various hormonal changes that stimulate the apocrine glands. These glands are responsible for producing sweat, which contains proteins and lipids. Unlike eccrine glands that are active from birth, apocrine glands only become active during puberty. They are mainly found in areas such as the armpits and genital region. The activation of apocrine glands during puberty is a normal physiological process.

    The dermis is the outermost and is made of stratified squamous cells. 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. The dermis is not the outermost layer of the skin. It is actually the second layer of the skin, located beneath the epidermis. The dermis is composed of connective tissue and contains various structures such as blood vessels, hair follicles, and sweat glands. The outermost layer of the skin is called the epidermis, which is made up of stratified squamous cells.

    Rate this question:

  • 9. 

    As new cells move toward the surface, their cytoplasm is replaced with the protein keratin.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    As new cells move toward the surface, their cytoplasm is replaced with the protein keratin. This process is known as keratinization, where the cytoplasm of the cells is gradually replaced by keratin, a tough and fibrous protein. This helps to strengthen and protect the cells as they reach the surface of the skin or other tissues. Therefore, the statement is true.

    You get new skin every 15-30 days.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    The human skin goes through a process called cell turnover, where old skin cells are shed and replaced with new ones. This process typically takes around 15-30 days for the skin to completely renew itself. Therefore, it is true that you get new skin every 15-30 days.

    Rate this question:

  • 18. 

    Nails are an accessory organ.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Nails are considered accessory organs because they are not vital for survival or the functioning of the body's major systems. They serve as a protective covering for the fingertips and help with fine motor skills. Although they may have some minor functions, such as aiding in picking up small objects or scratching, they are not essential organs like the heart, lungs, or kidneys. Therefore, the statement "Nails are an accessory organ" is true.

    What is the epidermis held together by?

    • Scotch tape

    • Glue

    • Keratin

    • Desmosomes

    Correct Answer
    A. Desmosomes
    Explanation
    The epidermis, which is the outermost layer of the skin, is held together by desmosomes. Desmosomes are specialized cell structures that act like "spot welds" between adjacent cells, providing strong adhesion and preventing the cells from easily separating. This helps to maintain the integrity and strength of the epidermis, allowing it to serve as a protective barrier for the underlying tissues and organs.

    Rate this question:

  • 26. 

    What epidermal layer undergoes mitosis, allows skin repair, and maintains an effective barrier?

    • Stratum spinosum

    • Stratum lucidum

    • Stratum corneum

    • Stratum germinativum

    Correct Answer
    A. Stratum germinativum
    Explanation
    The stratum germinativum is the correct answer because it is the deepest layer of the epidermis and is responsible for cell division through mitosis. This layer allows for skin repair by continuously producing new cells that migrate to the upper layers. It also maintains an effective barrier by producing keratinocytes that form the outermost layer of the skin, protecting it from the environment. The stratum spinosum, stratum lucidum, and stratum corneum are other layers of the epidermis but do not specifically undergo mitosis or play a role in skin repair.

    Rate this question:

  • 27. 

    Cyanosis is the increase in blood flow. Skin turns a bluish-gray color.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Cyanosis is actually the bluish-gray discoloration of the skin due to a decrease in blood flow or oxygenation. It occurs when there is a lack of oxygen in the blood, causing the skin to appear blue. Therefore, the statement that cyanosis is an increase in blood flow is incorrect.

    Rate this question:

  • 28. 

    What gives the skin it's tone?

    • Sweat glands

    • Keratin

    • Melanin

    • Vessels

    Correct Answer
    A. Melanin
    Explanation
    The skin's tone, or color, is primarily determined by the presence and amount of a pigment called melanin. Melanin is produced by specialized cells known as melanocytes, which are found in the epidermal layer of the skin. The variations in melanin production and distribution among individuals are responsible for differences in skin color.

    Rate this question:

  • 29.
