    • D.

      Hinge joint

    Correct Answer
    B. Amphiarthrosis
    Explanation
    Amphiarthrosis is the correct answer because it refers to a slightly movable joint. Unlike diarthroses, which are freely movable joints, and synarthrosis, which are immovable joints, amphiarthrosis joints allow for limited movement. Therefore, the correct answer is amphiarthrosis.

    Which Joint is locked and the strongest?

    • A.

      Diarthrosis

    • B.

      Amphiarthrosis

    • C.

      Synarthrosis

    • D.

      Gomphosis

    Correct Answer
    C. Synarthrosis
    Explanation
    Synarthrosis is the correct answer because it refers to a type of joint that is immovable and provides the strongest connection between bones. These joints are characterized by the presence of fibrous connective tissue that holds the bones together, such as in the sutures of the skull. This lack of movement allows for maximum stability and strength in the joint, making it the strongest among the options provided.

    What is an example of the Synarthrosis joint

    • A.

      Between the tibia and fibula

    • B.

      Between the right and left halves of the pelvis

    • C.

      Vertebrae of spinal column

    • D.

      Between the teeth and the jaws

    Correct Answer
    D. Between the teeth and the jaws
    Explanation
    The example of a synarthrosis joint is the joint between the teeth and the jaws. This joint is known as a gomphosis joint, where the teeth are firmly anchored into the sockets of the jawbone. This type of joint allows for very little or no movement, providing stability and support for the teeth during chewing and biting.

    What joint typically haves cartilage in between them ?

    • A.

      Amphiarthrosis

    • B.

      Synarthrosis

    • C.

      Diarthrosis

    • D.

      Synchondrosis

    Correct Answer
    A. Amphiarthrosis
    Explanation
    Amphiarthrosis joints typically have cartilage in between them. Amphiarthrosis joints are slightly movable joints, where the bones are connected by fibrocartilage or hyaline cartilage. This cartilage helps to absorb shock and provide stability to the joint. Examples of amphiarthrosis joints include the intervertebral discs in the spine and the pubic symphysis in the pelvis.

    What is The function of synovial fluid

    • A.

      Lubrication

    • B.

      Reduce friction

    • C.

      Nourish

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    Synovial fluid serves multiple functions in the body. Firstly, it acts as a lubricant, reducing friction between the joints and allowing smooth movement. Secondly, it helps to reduce friction by providing a cushioning effect, which protects the joints from wear and tear. Lastly, synovial fluid nourishes the cartilage in the joints by supplying it with essential nutrients and oxygen. Therefore, the correct answer is "all of the above" as synovial fluid performs all these functions.

    This movement extends the ankle joint and elevate the heel when you stand on your tip toe

    Correct Answer
    Plantar flexion
    Explanation
    Plantar flexion refers to the movement that extends the ankle joint and elevates the heel when standing on the tip toes. This movement is commonly observed during activities such as walking, running, and jumping. The muscles responsible for plantar flexion include the gastrocnemius, soleus, and other smaller muscles located in the calf region. When these muscles contract, they pull the heel upwards and allow for the body to be supported on the balls of the feet.

    This is the movement of the thumb toward the palm or finger tips that enables you to hold and grasp an object

    Correct Answer
    Opposition
    Explanation
    Opposition refers to the movement of the thumb towards the palm or fingertips, allowing for the ability to hold and grasp objects. This movement is essential for activities such as picking up small objects, gripping tools, and performing precise tasks with the hand. Opposition is made possible by the unique saddle joint between the thumb and the wrist, which provides a wide range of motion and allows for fine motor control. This movement is a key characteristic of the human hand and sets it apart from other primates.

    This is the twisting motion of the foot that turns the sole inward

    Correct Answer
    inversion
    Explanation
    Inversion refers to the twisting motion of the foot that turns the sole inward. This movement is commonly observed when the ankle rolls inward, causing the sole of the foot to face inward as well. Inversion is the opposite of eversion, which is the motion that turns the sole outward.

    Rate this question:

  • 11. 

    This is the twisting motion of the foot that turns the sole outward

    Correct Answer
    Eversion
    Explanation
    Eversion refers to the twisting motion of the foot that turns the sole outward. It is the opposite movement of inversion, which turns the sole inward. During eversion, the foot rolls outward, causing the outer edge of the foot to make contact with the ground. This motion is important for maintaining stability and balance during activities such as walking or running.

    Rate this question:

  • 12. 

    This is the flexion of the ankle joint and elevation of the sole

    Correct Answer
    Dorsiflexion
    Explanation
    Dorsiflexion refers to the flexion of the ankle joint and the elevation of the sole. This movement allows the foot to be brought closer to the shin, decreasing the angle between the foot and the leg. It is the opposite movement of plantarflexion, which involves pointing the toes downwards. Dorsiflexion is important for activities such as walking, running, and jumping, as it helps to lift the foot off the ground and maintain balance.

    Another name for Diarthrosis is free movement

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Diarthrosis is a type of joint that allows for free movement. It is also known as a synovial joint. This type of joint is characterized by the presence of a joint cavity, synovial fluid, and articular cartilage. Examples of diarthrosis joints include the shoulder joint and the knee joint. Therefore, the statement "Another name for Diarthrosis is free movement" is true.

    Osteoarthritis usually affects individuals age 18 and younger

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Osteoarthritis is a degenerative joint disease that commonly affects older individuals. It is characterized by the breakdown of cartilage in the joints, leading to pain and stiffness. While it is possible for osteoarthritis to occur in younger individuals, it is more commonly seen in those who are older, typically over the age of 40. Therefore, the statement that osteoarthritis usually affects individuals aged 18 and younger is false.

    Fat pads protect the articular cartilage and act as packing material

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Fat pads are present in various joints of the body, including the knee and shoulder joints. These fat pads serve as protective cushions for the underlying articular cartilage. They help distribute the forces and pressures exerted on the joint, reducing the risk of damage to the cartilage. Additionally, fat pads act as packing material, filling the spaces between the bones and providing stability to the joint. Therefore, the statement that fat pads protect the articular cartilage and act as packing material is true.

    Joints or articulations exist wherever two bones meet

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Joints or articulations are indeed present wherever two bones meet. These structures allow for movement and flexibility in the skeletal system. Without joints, our bodies would be rigid and unable to perform various activities such as walking, running, or even simple hand movements. Joints come in different forms, such as hinge joints (like the elbow), ball-and-socket joints (like the hip), or pivot joints (like the neck). They are crucial for maintaining mobility and enabling us to engage in everyday tasks.

    The classification of joints are Synovial, flexion, and gliding

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is incorrect. The classification of joints is not Synovial, flexion, and gliding. Synovial is not a classification of joints, but rather a type of joint characterized by the presence of synovial fluid. Flexion and gliding are not classifications of joints either, but rather types of movements that can occur at certain joints. Therefore, the correct answer is False.
