Anatomy: Bone Tissue II (The Shapes Of Bones) - Quiz

It’s time for another instalment of questions regarding bones, what they’re made of and how they work to make our lives just that little bit easier. What can you tell us about the shapes of these little lifesavers? Find out in this quiz on Anatomy: Bone Tissue II (the Shapes of Bones).


Questions and Answers
  • 1. 

    Describe Long Bone Shape.

    Explanation
    Long bones are characterized by their elongated shape, with the length being greater than their width. This shape allows long bones to provide support and leverage for movement. The longer length allows for a larger surface area for muscle attachment, enabling greater strength and mobility. Additionally, the elongated shape of long bones contributes to their function in bearing weight and providing structural support to the body.

    Name some long bones...

    Explanation
    The correct answer lists several examples of long bones in the human body. These include the humerus in the arm, the radius and ulna in the forearm, the metacarpals and phalanges in the hand, the metatarsals and phalanges in the foot, the femur in the thigh, and the tibia and fibula in the leg. Long bones are characterized by their elongated shape and provide support, mobility, and protection to the body.

    Short bones are nearly equal in __.

    Explanation
    Short bones are nearly equal in length and width. This means that the dimensions of short bones are relatively similar, resulting in a roughly cube-shaped or square-shaped bone. Unlike long bones, which are longer than they are wide, short bones have more balanced proportions. This characteristic allows short bones to provide stability and support to the body while also allowing for some movement. Examples of short bones include the bones of the wrist (carpals) and ankle (tarsals).

    Name some short bones...

    Explanation
    The correct answer includes the names of two short bones: carpal, which refers to the bones in the wrist, and tarsal, which refers to the bones in the ankle. Short bones are typically cube-shaped and provide stability and support to the body. These bones are found in areas that require a wide range of movement and flexibility, such as the wrist and ankle joints.

    Short bones have the following except...

    • A.

      Limited Motion

    • B.

      Merely Glide Across One Another

    • C.

      Flexibility

    Correct Answer
    C. Flexibility
    Explanation
    Short bones have limited motion and merely glide across one another, but they do not possess flexibility. Flexibility refers to the ability of a bone to bend or move easily. Short bones, such as the bones in the wrist and ankle, are primarily responsible for providing stability and support to the body. They are designed to withstand compressive forces rather than allowing for extensive movement. Therefore, flexibility is not a characteristic of short bones.

    Flat Bones do the following

    Correct Answer
    Enclose and Protect SOFT ORGANS
    Provide BROAD SURFACES for Muscle Attachment
    Explanation
    Flat bones, such as the skull, ribs, and sternum, have a unique structure that allows them to serve multiple functions. Firstly, they enclose and protect soft organs, such as the brain and organs in the thoracic and abdominal cavities, from external forces and potential injuries. Additionally, flat bones provide broad surfaces for muscle attachment, allowing muscles to anchor and exert force on the bone during movement. This attachment provides stability and support for the body, enabling efficient movement and protection of vital organs.

    Name some Flat Bones...

    Correct Answer
    Cranial Bones and the Ribs
    Sternum (Breastbone)
    Scapula (Short Blade)
    Os Coxae (Hipbone)
    Explanation
    The given answer lists examples of flat bones in the human body. Flat bones are thin and flat in shape, providing protection and serving as attachment sites for muscles. The cranial bones, which form the skull and protect the brain, are flat bones. The ribs are also flat bones that protect the organs in the chest cavity. The sternum, or breastbone, is a flat bone located in the center of the chest. The scapula, or shoulder blade, is another example of a flat bone that provides attachment for muscles. Lastly, the os coxae, or hipbone, is a flat bone that forms part of the pelvis.

    Irregular Bones have ___

    • A.

      Elaborate Shapes

    • B.

      Uniform Shapes

    • C.

      Equatorial Shapes

    • D.

      Longitudinal Shapes

    • E.

      Normal Shapes

    Correct Answer
    A. Elaborate Shapes
    Explanation
    Irregular bones have elaborate shapes. Unlike other types of bones, which have a relatively uniform shape, irregular bones have complex and varied shapes. This allows them to fulfill specific functions in the body, such as providing protection or supporting weight. Examples of irregular bones include the vertebrae, facial bones, and hip bones. Their elaborate shapes make them unique and distinguishable from other bone types.
