    The nail plate is made of dead cells, therefore they do not need________________.

    • A.

      Water

    • B.

      Oxygen

    • C.

      Keratin

    • D.

      Vitamin D

    Correct Answer
    B. Oxygen
    Explanation
    The nail plate is made up of dead cells that do not require oxygen for their metabolic processes. Oxygen is needed by living cells to carry out cellular respiration, but since the nail plate is composed of non-living cells, it does not need oxygen to survive.

    Cuticle moisturizers are designed to treat the eponychium, hyponychium, and the sidewalls but not the _____________________.

    • A.

      Cuticle

    • B.

      Nail bed

    • C.

      Nail plate

    • D.

      Free edge

    Correct Answer
    A. Cuticle
    Explanation
    Cuticle moisturizers are specifically formulated to target and treat the eponychium, hyponychium, and the sidewalls of the nails. These areas are prone to dryness, cracking, and irritation. However, the cuticle itself does not require additional moisturizing as it is already a protective layer that seals the nail plate and nail bed. Therefore, cuticle moisturizers are not intended to be applied directly on the cuticle.

      Nail folds

    • D.

      Nail grooves

    Correct Answer
    B. Hyponychium
    Explanation
    The hyponychium is the layer of skin that lies between the fingertip and the free edge of the natural nail plate. It helps to seal the nail bed and protect it from infection. The eponychium refers to the cuticle, the nail folds are the skin on the sides of the nail, and the nail grooves are the depressions on the sides of the nail.

    A tough band of fibrous tissue that connects bones and holds organs in place.

    • A.

      Nail cuticle

    • B.

      Sidewall

    • C.

      Natural nail unit

    • D.

      Ligament

    Correct Answer
    D. Ligament
    Explanation
    A ligament is a tough band of fibrous tissue that connects bones and holds organs in place. Ligaments are flexible yet strong, allowing for movement while providing stability and support to the joints. They play a crucial role in maintaining the structural integrity of the body and preventing excessive movement or dislocation of bones. Unlike the other options listed (nail cuticle, sidewall, natural nail unit), ligaments are not specific to the nails or skin but are found throughout the body.

    • C.

      Lanula

    • D.

      Nail grooves

    Correct Answer
    C. Lanula
    Explanation
    The correct answer is "lanula." The lanula is the white half-moon shape at the base of the nail. It is a visible part of the nail matrix, which is responsible for producing the cells that make up the nail plate. The lanula appears white because it is thicker and less transparent than the rest of the nail plate. It is often used as a reference point for nail health and growth.

    • C.

      Matrix

    • D.

      Natural nail

    Correct Answer
    C. Matrix
    Explanation
    The matrix is the correct answer because it is the part of the nail where the nail plate cells are formed and composed. The matrix cells are responsible for producing the nail plate, which is the hard, visible part of the nail. The hyponychium is the area of skin beneath the free edge of the nail, the nail bed is the area beneath the nail plate, and the natural nail refers to the entire nail unit.

    • C.

      1-2 months

    • D.

      9 months

    Correct Answer
    B. 4-6 months
    Explanation
    A fingernail replacement takes approximately 4-6 months because it takes time for a new nail to grow and fully replace the old one. The process of nail growth is gradual and can vary from person to person, but on average it takes several months for a new nail to fully form. During this time, the old nail may gradually detach and fall off, allowing the new nail to take its place.

    On which finger does the nail grow the slowest.

    • A.

      Pinky

    • B.

      Ring finger

    • C.

      Middle finger

    • D.

      Thumb

    Correct Answer
    D. Thumb
    Explanation
    The nail on the thumb grows the slowest because it has the least amount of blood flow compared to the other fingers. The blood flow to the nail bed is essential for nail growth, and since the thumb is physically smaller than the other fingers, it receives less blood supply, resulting in slower nail growth.
