Skeletal System: Anatomy And Physiology Trivia - Quiz

How much do you know about the human body? Do you know your stuff, or are you at a loss when it comes to information beyond being comprised of bones? Find out in this quiz on anatomy and physiology.


Questions and Answers
  • 1. 

    What is the bone the arrow points to?

    • A.

      Scapula

    • B.

      Fibula

    • C.

      Humerus

    • D.

      Radius

    Correct Answer
    C. Humerus
    Explanation
    The arrow in the question is pointing to a bone, and the correct answer is "Humerus." The humerus is the bone located in the upper arm, between the shoulder and the elbow. It is the longest and largest bone in the upper limb, and it connects the scapula (shoulder blade) to the radius and ulna in the forearm.

    How many bones does the average fully grown adult have?

    • A.

      300

    • B.

      296

    • C.

      283

    • D.

      206

    Correct Answer
    D. 206
    Explanation
    The average fully grown adult has 206 bones. This is because as we grow from infancy to adulthood, some of our bones fuse together. At birth, we have around 300 bones, but as we age, these bones gradually fuse, resulting in a decrease in the total number of bones.

  • 3. 

    What is the longest bone in the human body?

    • A.

      Tibia

    • B.

      Femur

    • C.

      Ulna

    • D.

      Illium

    Correct Answer
    B. Femur
    Explanation
    The femur is the longest bone in the human body. It is located in the thigh and extends from the hip to the knee. The length of the femur allows for stability and support, as well as the ability to withstand the forces exerted on it during activities such as walking, running, and jumping. Its length also provides leverage for the muscles that attach to it, allowing for efficient movement.

  • 4. 

    The function of a ______ is to connect the muscle to the bone..

    • A.

      Ligament

    • B.

      Tendon

    • C.

      Joint

    • D.

      Cartilage

    Correct Answer
    B. Tendon
    Explanation
    A tendon is a fibrous connective tissue that connects muscle to bone. It is responsible for transmitting the force generated by the muscle to the bone, allowing movement and providing stability to the joint. Unlike ligaments, which connect bone to bone, tendons specifically connect muscle to bone. Therefore, the correct answer is tendon.

    Rate this question:

  • 5. 

    A ________ joint exists in the elbow.

    • A.

      Ball and Socket

    • B.

      Gliding

    • C.

      Epsiloid

    • D.

      Hinge

    Correct Answer
    D. Hinge
    Explanation
    A hinge joint exists in the elbow because it allows for movement in only one plane, similar to a door hinge. This type of joint allows for flexion and extension, but restricts other types of movement such as rotation or side-to-side motion. The elbow joint acts like a hinge, allowing the forearm to bend and straighten, while the upper arm remains relatively stable.

  • 6. 

    One of yellow bone marrow's functions is too..

    • A.

      Store fat

    • B.

      Create proteins

    • C.

      Create red blood cells

    • D.

      All of the above

    Correct Answer
    A. Store fat
    Explanation
    Yellow bone marrow is primarily responsible for storing fat in the body. It is composed of adipocytes, which are specialized cells that store excess energy in the form of fat. This stored fat can be used as a source of energy during times of fasting or when the body requires additional energy. Therefore, the correct answer is "Store fat."

    Rate this question:

  • 7. 

    Which of these is NOT a type of vertebrae?

    • A.

      Lumbar Vertebrae

    • B.

      Thoracic Vertebrae

    • C.

      Sacral Vertebrae

    • D.

      Cervical Vertebrae

    Correct Answer
    C. Sacral Vertebrae
    Explanation
    The sacral vertebrae are indeed a type of vertebrae. They are five fused vertebrae located in the lower back and form the sacrum. The lumbar vertebrae are also a type of vertebrae, located in the lower back. The thoracic vertebrae are located in the mid-back and the cervical vertebrae are located in the neck. Therefore, the correct answer is Sacral Vertebrae.
