    The skin is the organ of __________________.

    • Smell

    • Touch

    • Hearing

    • Sight

    Correct Answer
    A. Touch
    Explanation
    The skin is the organ responsible for the sense of touch. It contains numerous sensory receptors that detect pressure, temperature, and pain, allowing us to perceive and interact with our environment. These receptors send signals to the brain, which processes the information and enables us to feel sensations such as texture, pressure, and vibration. The skin also acts as a protective barrier, regulating body temperature, and preventing the loss of essential fluids. Overall, the skin plays a crucial role in our ability to experience and navigate the world through the sense of touch.

    The outer layer of the skin is called the __________

    • Epidermis

    • Dermis

    • Follicle

    • Sweat gland

    Correct Answer
    A. Epidermis
    Explanation
    The outer layer of the skin is called the epidermis. It is the topmost layer of the skin and acts as a protective barrier against external factors such as bacteria, UV radiation, and chemicals. The epidermis is composed of multiple layers of cells, including keratinocytes, which produce a tough protein called keratin that helps to strengthen and waterproof the skin. It also contains melanocytes, which produce melanin, the pigment responsible for skin color. The epidermis constantly regenerates itself by shedding dead skin cells and replacing them with new ones from the lower layers.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Exposure to excessive sunlight can be harmful to the skin as it can lead to sunburn, premature aging, and an increased risk of skin cancer. While sunlight is a natural source of vitamin D, it is important to balance sun exposure and protect the skin by wearing sunscreen, seeking shade, and using protective clothing. Therefore, the statement that we should expose our skin to a lot of sunlight is false.

    The openings on the skin surface are called ______________________.

    Correct Answer
    pores
    Explanation
    The openings on the skin surface are called pores. Pores are tiny openings in the skin that allow sweat and oil to reach the surface. They play a crucial role in regulating body temperature and keeping the skin moisturized. Pores can become clogged with dirt, oil, and dead skin cells, leading to various skin issues like acne and blackheads. Proper skincare and cleansing routines can help keep the pores clean and minimize their appearance.

    Correct Answer
    outer
    Explanation
    Dead cells make up the outer layer of the skin. This layer, also known as the epidermis, is composed of several layers of cells, with the outermost layer consisting of dead skin cells. These dead cells provide a protective barrier for the underlying layers of skin and help to prevent the entry of harmful substances and bacteria.

    Correct Answer
    A. 2
    Explanation
    The skin has two main layers: the epidermis and the dermis. The epidermis is the outermost layer of the skin and provides protection against the environment. The dermis is the layer beneath the epidermis and contains various structures such as blood vessels, hair follicles, and sweat glands. These two layers work together to maintain the integrity and function of the skin.

    Explanation
    Hair and nails are special parts of the skin because they are both made up of a tough protein called keratin. Hair helps to protect the scalp from the sun and provides insulation, while nails protect the fingertips and provide support for delicate tissues. Both hair and nails also play a role in sensory perception, as they have nerve endings that can detect touch and pressure.
