    A bone with approximately the same width, length and height is most likely:

    • A.

      A long bone

    • B.

      A short bone

    • C.

      A flat bone

    • D.

      An irregular bone

    Correct Answer
    B. A short bone
    Explanation
    A bone with approximately the same width, length, and height is most likely a short bone. Short bones are typically cube-shaped or have a similar width, length, and height. These bones provide support and stability to the body and are found in areas such as the wrists and ankles. They are not as long as long bones, which are found in the arms and legs, and they are not flat like flat bones, such as the ribs or scapula. Additionally, they are not irregularly shaped like irregular bones, such as the vertebrae. Therefore, a bone with these dimensions is most likely a short bone.

    An osteon has:

    • A.

      A central canal carrying blood vessels

    • B.

      Concentric lamellae

    • C.

      Osteocytes in lucanae

    • D.

      Canaliculi that connect lacunae to the central canal

    • E.

      All of these

    Correct Answer
    E. All of these
    Explanation
    An osteon is a structural unit of compact bone. It consists of concentric lamellae, which are layers of bone tissue that surround a central canal. The central canal carries blood vessels, allowing for the transportation of nutrients and oxygen to the bone cells. Osteocytes, which are mature bone cells, are located in small spaces called lacunae within the lamellae. Canaliculi are tiny channels that connect the lacunae to the central canal, allowing for the exchange of nutrients and waste products between osteocytes and blood vessels. Therefore, all of these structures are present in an osteon.

    The flat bones of the skull develop from

    • A.

      Areolar tissue

    • B.

      Hyaline cartilage

    • C.

      Fibrous connective tissue

    • D.

      Compact bone

    Correct Answer
    C. Fibrous connective tissue
    Explanation
    The flat bones of the skull develop from fibrous connective tissue. During fetal development, the skull bones start as fibrous connective tissue membranes called fontanelles. These fontanelles gradually ossify and transform into the flat bones of the skull. Fibrous connective tissue provides flexibility and allows for the growth and shaping of the skull bones as the baby's brain grows. As ossification occurs, the fibrous connective tissue is replaced by compact bone, resulting in the formation of the flat bones of the skull.

    • D.

      Osteoblasts and osteocytes

    Correct Answer
    B. Osteoblasts and osteoclasts
    Explanation
    The remodeling of bone refers to the continuous process of breaking down old bone tissue and replacing it with new bone tissue. This process is carried out by two types of cells: osteoblasts and osteoclasts. Osteoblasts are responsible for the formation of new bone tissue, while osteoclasts are responsible for the breakdown and resorption of old bone tissue. Together, these cells work to maintain the balance and integrity of the skeletal system.

    Bone remodeling in adults is regulated and directed mainly by:

    • A.

      Growth hormone

    • B.

      Thyroid hormones

    • C.

      Sex hormones

    • D.

      Mechanical stress & PTH

    Correct Answer
    D. Mechanical stress & PTH
    Explanation
    Bone remodeling in adults is regulated and directed mainly by mechanical stress and parathyroid hormone (PTH). Mechanical stress refers to the physical forces applied to the bones during activities such as weight-bearing exercises. These forces stimulate bone cells to remodel and strengthen the bone tissue. PTH, on the other hand, is a hormone produced by the parathyroid glands that plays a crucial role in maintaining calcium balance in the body. It stimulates bone resorption, which is the process of breaking down old bone tissue, and promotes the release of calcium into the bloodstream. Together, mechanical stress and PTH ensure the continuous renewal and adaptation of bone tissue to meet the body's needs.

    Where within the epiphyseal plate are the dividing cartilage cells located?

    • A.

      Nearest the shaft

    • B.

      In the marrow cavity

    • C.

      Farthest from the shaft

    • D.

      In the primary ossification center

    Correct Answer
    C. Farthest from the shaft
    Explanation
    The dividing cartilage cells within the epiphyseal plate are located farthest from the shaft. This is because the epiphyseal plate is responsible for longitudinal bone growth, and the dividing cartilage cells are actively multiplying to lengthen the bone. As new cells are produced, they push the older cells away from the shaft, causing them to move towards the ends of the bone, which are farthest from the shaft.

    Wolff's law is concerned with:

    • A.

      Calcium homeostasis of the blood

    • B.

      The thickness and shape of a bone being determined by mechanical and gravitational stresses placed on it

    • C.

      The electric charge on bone surfaces

    Correct Answer
    B. The thickness and shape of a bone being determined by mechanical and gravitational stresses placed on it
    Explanation
    Wolff's law states that the structure and shape of a bone are influenced by the mechanical and gravitational forces acting upon it. This means that bones will adapt and remodel themselves in response to the stresses placed upon them. For example, if a bone is subjected to increased mechanical loads, it will become thicker and stronger to withstand the forces. Similarly, if the bone is not exposed to sufficient stress, it may become weaker and more prone to fractures. Therefore, Wolff's law is concerned with how the thickness and shape of bones are determined by mechanical and gravitational stresses.

    Formation of the bony callus in fracture repair is followed by:

    • A.

      Hematoma formation

    • B.

      Fibrocartilaginous callus formation

    • C.

      Bone remodeling to convert woven bone to compact bone

    • D.

      Formation of granulation tissue

    Correct Answer
    C. Bone remodeling to convert woven bone to compact bone
    Explanation
    The correct answer is bone remodeling to convert woven bone to compact bone. After the formation of the bony callus, which is a bridge of new bone that stabilizes the fracture, the next step in fracture repair is the remodeling of the woven bone. Woven bone is initially formed as a temporary replacement for the fractured bone, but it is structurally weak and disorganized. Through the process of bone remodeling, the woven bone is gradually replaced by compact bone, which is stronger and more organized. This remodeling process involves the removal of excess bone tissue and the addition of new bone tissue, resulting in the restoration of the bone's normal structure and strength.

  • 13. 

    The fracture type in which the bone ends are incompletely separated is:

    • A.

      Greenstick

    • B.

      Compound

    • C.

      Simple

    • D.

      Comminuted

    Correct Answer
    A. Greenstick
    Explanation
    A greenstick fracture is a type of fracture where the bone is partially broken and the ends are incompletely separated. This type of fracture is commonly seen in children because their bones are more flexible and less brittle than adults. In a greenstick fracture, the bone bends and cracks, but does not completely break. It is called "greenstick" because it is similar to bending a green stick, which will crack on the outside but remain intact on the inside.

    The disorder in which bones are porous and thin but bone composition is normal is:

    • A.

      Osteomalacia

    • B.

      Osteoporosis

    • C.

      Paget's disease

    Correct Answer
    B. Osteoporosis
    Explanation
    Osteoporosis is a disorder characterized by porous and thin bones, despite having a normal bone composition. This condition occurs when the body loses too much bone mass or fails to produce enough bone, resulting in weak and brittle bones. Osteomalacia, on the other hand, is a condition where the bones become soft and weak due to a lack of vitamin D or calcium. Paget's disease is a condition where the bones become weak and deformed due to abnormal bone remodeling. Therefore, the correct answer is osteoporosis.

    B. Diarthroses
    Explanation
    Diarthroses are freely movable joints. These joints have a wide range of motion and are commonly found in the limbs. They are characterized by the presence of a synovial cavity, which is filled with synovial fluid that lubricates the joint and reduces friction. Diarthroses allow for smooth and fluid movements, such as bending, straightening, and rotating. Examples of diarthroses include the shoulder joint, hip joint, and knee joint.

    Anatomical characteristics of a synovial joint include:

    • A.

      Articular cartilage

    • B.

      A joint cavity

    • C.

      An articular capsule

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    The anatomical characteristics of a synovial joint include articular cartilage, a joint cavity, and an articular capsule. Articular cartilage covers the ends of the bones, allowing smooth movement and reducing friction. The joint cavity is a space filled with synovial fluid, which lubricates the joint and provides nutrients to the cartilage. The articular capsule surrounds the joint, providing stability and containing the synovial fluid. Therefore, all of these characteristics are present in a synovial joint.

    Factors that influence the stability of a synovial joint include:

    • A.

      Shape of articular surfaces

    • B.

      Presence of strong reinforcing ligaments

    • C.

      Tone of surrounding muscles

    • D.

      All of these

    Correct Answer
    D. All of these
    Explanation
    The stability of a synovial joint is influenced by multiple factors. The shape of the articular surfaces plays a crucial role as it determines how well the bones fit together and the range of motion allowed. The presence of strong reinforcing ligaments provides additional support and prevents excessive movement or dislocation of the joint. Additionally, the tone of the surrounding muscles helps stabilize the joint by providing dynamic support and controlling its movement. Therefore, all of these factors contribute to the overall stability of a synovial joint.
