    Correct Answer
    A. Detoxify the body
    Explanation
    The sudoriferous glands, also known as sweat glands, play a vital role in the body's detoxification process. When the body temperature rises due to physical activity, hot weather, or stress, these glands produce sweat, which is mostly composed of water along with small amounts of salts and other compounds. As sweat evaporates from the skin's surface, it helps cool down the body.

    Sensory nerve fibers are responsible for detecting and transmitting information about heat, cold, touch, pressure, and pain. These fibers are found throughout the body and are connected to sensory receptors in the skin, muscles, and organs. When these receptors are stimulated by external stimuli or internal changes, the sensory nerve fibers send signals to the brain, allowing us to perceive and respond to different sensory sensations.

    Nerve endings that are sensitive to touch & pressure are found in which layer of the skin?

    • Reticular layer

    • Stratum corneum

    • Papillary layer

    • Stratum lucidum

    Correct Answer
    A. Papillary layer
    Explanation
    The nerve endings that are sensitive to touch and pressure are found in the papillary layer of the skin. This layer is located just beneath the epidermis and is responsible for providing the skin with its sensitivity. It contains numerous small blood vessels and nerve endings, making it highly sensitive to touch and pressure stimuli. The other options, such as the reticular layer, stratum corneum, and stratum lucidum, do not contain as many nerve endings and are not primarily responsible for the sense of touch and pressure.
