    Bones are attached to other bones by

    • A.

      Ligaments

    • B.

      Tendons

    • C.

      Cartilage

    • D.

      Muscle

    Correct Answer
    A. Ligaments
    Explanation
    Ligaments are fibrous connective tissues that attach bones to other bones. They are responsible for providing stability and support to joints, allowing for movement while preventing excessive motion. Unlike tendons, which connect muscles to bones, ligaments do not play a direct role in muscle movement. Similarly, cartilage is a type of connective tissue that covers the ends of bones, providing cushioning and reducing friction in joints, but it does not directly attach bones to each other. Therefore, the correct answer is ligaments.

    Bone is rebuilt by

    • A.

      Osteoblasts

    • B.

      Osteoclasts

    • C.

      Osteoporosis

    • D.

      Osteopenia

    Correct Answer
    A. Osteoblasts
    Explanation
    Bone is rebuilt by osteoblasts. Osteoblasts are specialized cells responsible for the formation of new bone tissue. They secrete proteins and other substances that help in the mineralization of bone, leading to its growth and repair. Osteoblasts work in conjunction with osteoclasts, which are responsible for the breakdown and resorption of old bone tissue. However, in the context of bone rebuilding, osteoblasts play a crucial role in the synthesis and deposition of new bone material. Osteoporosis and osteopenia are conditions characterized by a decrease in bone density and mass, but they do not directly participate in the process of bone rebuilding.

    • D.

      Cause injury

    Correct Answer
    A. Incease
    Explanation
    A walking program can have a positive effect on bone density. Regular weight-bearing exercises like walking stimulate the bones to become stronger and denser. This is because when you walk, your body weight puts stress on the bones, which triggers the bone-building process. Over time, this can lead to an increase in bone density, making the bones less prone to fractures and osteoporosis. Therefore, the correct answer is "Increase".

    What is osteoarthritis?

    • A.

      Fragile bones

    • B.

      Bone development

    • C.

      Bone remodelling

    • D.

      Bone calcification

    Correct Answer
    A. Fragile bones
    Explanation
    Osteoarthritis is a degenerative joint disease that primarily affects the cartilage in the joints. It is characterized by the breakdown of cartilage, which leads to joint pain, stiffness, and loss of function. Fragile bones, on the other hand, refer to a condition called osteoporosis, where the bones become weak and prone to fractures. While osteoarthritis can lead to joint damage and potentially contribute to bone fragility, the two conditions are distinct and have different underlying causes.

    • A.

      Osteoporosis

    • B.

      Broken bones

    • C.

      Osteopenia

    • D.

      Osteoponation

    Correct Answer
    A. Osteoporosis
    Explanation
    Inactivity over a long period of time can lead to osteoporosis, which is a condition where the bones become weak and brittle. Lack of physical activity and weight-bearing exercises can cause a decrease in bone density and mineral content. This can result in an increased risk of fractures and broken bones. Osteopenia is a milder form of bone loss that can also occur due to inactivity, but osteoporosis is a more severe and advanced stage of bone deterioration. Osteoponation is not a recognized medical condition or term.
