Questions and Answers
  • 1. 

    Which of the following is a joint that allows movement in only one direction?

    • A.

      Ball and socket

    • B.

      Hinge

    • C.

      Pivot

    • D.

      Gliding

    Correct Answer
    B. Hinge
    Explanation
    A hinge joint is a type of joint that allows movement in only one direction. It is formed by the articulation of two bones, with one bone having a convex surface that fits into the concave surface of the other bone. This design restricts movement to a single plane, such as the bending and straightening of a joint, like the elbow or knee. Unlike ball and socket joints, pivot joints, and gliding joints, which allow for multi-directional movement, a hinge joint is specifically designed for unidirectional movement.

    The joints of the hips and shoulders are an example of what type of joint?

    • A.

      Gliding

    • B.

      Hinge

    • C.

      Pivot

    • D.

      Ball and socket

    Correct Answer
    D. Ball and socket
    Explanation
    The joints of the hips and shoulders are classified as ball and socket joints. This type of joint allows for a wide range of movement in multiple directions, similar to how a ball can rotate freely in a socket. The rounded end of one bone fits into the cup-shaped socket of another bone, allowing for movements such as flexion, extension, abduction, adduction, and rotation. This design provides stability and strength to these joints, making them suitable for weight-bearing and dynamic movements.

  • 3. 

    The blood cells are made in the _________.

    • A.

      Liver

    • B.

      Heart

    • C.

      Bone marrow

    • D.

      Brain

    Correct Answer
    C. Bone marrow
    Explanation
    The bone marrow is responsible for the production of blood cells. It is a soft, spongy tissue found inside the bones. Red blood cells, white blood cells, and platelets are all produced in the bone marrow. The liver, heart, and brain do not play a role in the production of blood cells.

    Rate this question:

  • 4. 

    The surface of bones is covered by _________.

    • A.

      Periosteum

    • B.

      Muscles

    • C.

      Ligaments

    • D.

      Tendons

    Correct Answer
    A. Periosteum
    Explanation
    The surface of bones is covered by periosteum, a dense layer of connective tissue. The periosteum plays a crucial role in bone growth, repair, and nutrition. It contains blood vessels, nerves, and cells that are involved in bone formation and remodeling. Additionally, the periosteum provides protection to the underlying bone and serves as an attachment site for tendons and ligaments.

  • 5. 

    A place where two or more bones meet is called a ________.

    • A.

      Socket

    • B.

      Hinge

    • C.

      String

    • D.

      Joint

    Correct Answer
    D. Joint
    Explanation
    A joint is the correct answer because it refers to the specific location where two or more bones come together. It is the point of connection between bones, allowing for movement and flexibility in the body. A joint can be found in various parts of the body, such as the knees, elbows, and shoulders, and it plays a crucial role in enabling different types of movements.

    Rate this question:

  • 6. 

    Bone-forming cells are called                          .

    • A.

      Chondroclasts

    • B.

      Chondroblasts

    • C.

      Osteoblasts

    • D.

      Osteoclasts

    Correct Answer
    C. Osteoblasts
    Explanation
    Osteoblasts are bone-forming cells. They are responsible for the synthesis and secretion of the organic components of the bone matrix, including collagen and other proteins. Osteoblasts play a crucial role in bone development, growth, and repair. They are involved in the process of bone mineralization, where they deposit calcium and other minerals onto the bone matrix, leading to the formation of new bone tissue. Osteoblasts also regulate the activity of osteoclasts, which are responsible for bone resorption. Overall, osteoblasts are essential for maintaining bone health and integrity.

    Which of these is/are types of cartilage?

    • A.

      Hyaline Cartilage

    • B.

      Elastic Cartilage

    • C.

      Fibrocartilage

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Hyaline cartilage, elastic cartilage, and fibrocartilage are all types of cartilage. Hyaline cartilage is the most common type and is found in the nose, trachea, and ends of long bones. Elastic cartilage contains elastic fibers and is found in the external ear and epiglottis. Fibrocartilage is the toughest type and is found in the intervertebral discs and knee joint. Therefore, all three options are correct and represent different types of cartilage in the body.

    What is the type of pivot joint between the atlas and the axis?

    • A.

      Synovial joint

    • B.

      Saddle joint

    • C.

      Fibrous joint

    • D.

      Cartilaginous joint

    Correct Answer
    A. Synovial joint
    Explanation
    The atlas and the axis are the first two vertebrae in the neck, and they form a pivot joint. A pivot joint allows rotation around a central axis, which is necessary for the head to turn from side to side. A synovial joint is a type of joint that is characterized by a fluid-filled cavity and allows for a wide range of movement. Therefore, the correct answer is synovial joint.

    What is the knee also known as?

    • A.

      Femur

    • B.

      Patella

    • C.

      Tarsal

    • D.

      Carpal

    Correct Answer
    B. Patella
    Explanation
    The knee is also known as the patella. The patella is a small bone located in the front of the knee joint. It acts as a protective covering for the knee joint and helps to increase the leverage of the thigh muscles. The patella also plays a crucial role in the stability and movement of the knee joint.

    Rate this question:

  • 10. 

    Which of the following is/are parts of the skullbone?

    • A.

      Nasal bone

    • B.

      Tibia

    • C.

      Parietal bone

    • D.

      Both A & C

    Correct Answer
    D. Both A & C
    Explanation
    The correct answer is "Both A & C". The nasal bone and parietal bone are both parts of the skull. The nasal bone is located in the upper part of the nose, while the parietal bone is one of the main bones that forms the top and sides of the skull. The tibia, on the other hand, is a bone in the lower leg and is not part of the skull.
