    How can you  creat Vitamin D in skin cells?

    • A.

      Influence of sunlight

    • B.

      Influence of activity

    • C.

      During sleeping

    • D.

      During eating

    Correct Answer
    A. Influence of sunlight
    Explanation
    Exposure to sunlight is responsible for the creation of Vitamin D in skin cells. When the skin is exposed to sunlight, it triggers a reaction that converts a substance in the skin called 7-dehydrocholesterol into Vitamin D3. This inactive form of Vitamin D is then converted into its active form by the liver and kidneys. Therefore, the influence of sunlight is crucial for the production of Vitamin D in skin cells.

    Correct Answer(s)
    A. Inhibits the rease of calcium from bone
    B. Reduces osteoclast activity
    C. Inhibits vitamin D activation in the kidney
    D. Inhibits calcium reabsorption by the kidney
    Explanation
    Calcitonin is a hormone that is responsible for inhibiting the release of calcium from the bone. It also reduces the activity of osteoclasts, which are cells that break down bone tissue. Additionally, calcitonin inhibits the activation of vitamin D in the kidney, which is necessary for the absorption of calcium. Finally, it also inhibits the reabsorption of calcium by the kidney.

    Explanation
    The most common fractures are those resulting from sudden injury.

  • 23. 

    Identify the steps in the treatment and recovery process of a fracture.

    • A.

      Reduction

    • B.

      Immobilization

    • C.

      Restore function/rehab

    Correct Answer
    A. Reduction
    Explanation
    Reduction is the first step in the treatment and recovery process of a fracture. It involves realigning the broken bones to their normal position. This can be done through manual manipulation or surgical intervention. Once the bones are properly aligned, the next step is immobilization. This is done by applying casts, splints, or other devices to keep the bones in place and prevent further movement. Immobilization helps in the healing process. Lastly, after the fracture has healed, the focus shifts to restoring function and rehabilitating the affected area. This may involve physical therapy, exercises, and other interventions to regain strength, flexibility, and mobility.

    Where is the most common site of gout?

    • A.

      Big toe

    • B.

      Ankle

    • C.

      Knee

    • D.

      Heel

    Correct Answer
    A. Big toe
    Explanation
    Gout is a form of arthritis that occurs when there is a build-up of uric acid crystals in the joints. The most common site for gout to occur is in the big toe joint. This is because the big toe joint is often subjected to more stress and pressure, making it more susceptible to inflammation and the deposition of uric acid crystals. Additionally, the temperature of the big toe joint is slightly lower than other joints, which further promotes the formation of crystals. Therefore, the big toe is the most common site of gout.

    Rate this question:

  • 33. 

    The pathogenesis of gout resides in an elevation of  _____ levels.

    • A.

      Serum uric acid

    • B.

      Purine

    • C.

      Salvage

    • D.

      Nucleic acids

    Correct Answer
    A. Serum uric acid
    Explanation
    Gout is a form of arthritis caused by the buildup of uric acid crystals in the joints. The pathogenesis, or development, of gout is linked to elevated levels of serum uric acid. When there is an excess of uric acid in the blood, it can form crystals in the joints, leading to inflammation and pain. Therefore, maintaining normal levels of serum uric acid is crucial in preventing and managing gout.

    • B.

      Osteoclasts

    Correct Answer
    B. Osteoclasts
    Explanation
    Osteoclasts are cells responsible for breaking down bone tissue during the process of bone remodeling and growth. They play a crucial role in maintaining bone density and shape by removing old or damaged bone tissue. This process allows for the continual renewal and repair of bone throughout life. Osteoclasts are vital for maintaining bone health and are regulated by various hormones and signaling molecules in the body.
