    Correct Answer
    A. Vertebrae
    Explanation
    The correct answer is Vertebrae. The bones in your spine are called vertebrae. These vertebrae are stacked on top of each other and form the vertebral column, which protects the spinal cord and provides support for the body. Each vertebra has a bony ring and a bony arch that surrounds and protects the spinal cord. The vertebrae are connected by intervertebral discs, which act as shock absorbers and allow for flexibility in the spine.

    Explanation
    Bone marrow is the correct answer because it is located in the center of a bone. Bone marrow is a soft, spongy tissue that is responsible for the production of blood cells, including red blood cells, white blood cells, and platelets. It also contains fat cells and provides support and nourishment to the surrounding bone tissue.

    • Heart

    • Lungs

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The rib cage is a bony structure that encloses and protects several vital organs in the chest cavity. The liver, heart, and lungs are all located within the rib cage. The liver, the largest internal organ, is protected by the lower ribs on the right side. The heart, a crucial organ for pumping blood, is surrounded and shielded by the rib cage. The lungs, responsible for breathing, are also housed within the rib cage and are protected from external damage. Therefore, all of the above organs are protected by the rib cage.

    Your bones will stop growing by the time you're:

    • 93

    • 25

    • 30

    • 13

    Correct Answer
    A. 25
    Explanation
    Bones stop growing once a person reaches their full adult height, which typically occurs around the age of 25. After this age, the growth plates in the bones close and the bones solidify, preventing any further growth in length. While bones continue to undergo remodeling and repair throughout a person's life, they no longer grow in size or length after reaching adulthood. Therefore, the correct answer is 25.

    A. 26
    Explanation
    The spine, also known as the vertebral column, is made up of 26 bones called vertebrae. These vertebrae are stacked on top of each other and are divided into different regions, including the cervical, thoracic, lumbar, sacral, and coccygeal regions. Each region has a specific number of vertebrae, with the cervical region having 7, the thoracic region having 12, the lumbar region having 5, the sacral region having 5 fused vertebrae, and the coccygeal region having 3-5 fused vertebrae. Therefore, the correct answer is 26.

It is located in the middle ear and plays a crucial role in transmitting sound vibrations from the eardrum to the inner ear. The stirrup is approximately 2.8 to 3.3 millimeters in length, making it the tiniest bone in the body.
