Skeletal System Quiz: Multiple Choice Questions - Quiz

.


Questions and Answers
  • 1. 

    Which part of the skeletal system is the rigid frame work?

    • A.

      Endoskeleton

    • B.

      Tendon

    • C.

      Skin

    • D.

      Joints

    Correct Answer
    A. Endoskeleton
    Explanation
    The endoskeleton is the correct answer because it refers to the internal framework of bones that provides support, protection, and shape to the body. It is the rigid structure that gives the body its form and allows for movement. Tendons, skin, and joints are not part of the skeletal system and do not serve as the rigid framework of the body.

    What is the periosteum?

    • A.

      Acids inside bones

    • B.

      Soft tissue in bones

    • C.

      Tough membrane that surronds bone

    • D.

      Connective tissue

    Correct Answer
    C. Tough membrane that surronds bone
    Explanation
    The periosteum is a tough membrane that surrounds bones. It serves as a protective covering for bones and contains blood vessels, nerves, and cells involved in bone growth and repair. The periosteum also plays a role in anchoring tendons and ligaments to the bone surface.

    Is a spongy bone feel like a sponge?

    • A.

      No

    • B.

      Yes

    Correct Answer
    B. Yes
    Explanation
    Yes, a spongy bone does feel like a sponge. Spongy bone, also known as cancellous bone, is found at the ends of long bones and inside the vertebrae. It has a porous and honeycomb-like structure, similar to that of a sponge. This structure provides strength and support while also reducing the weight of the bone. Additionally, spongy bone contains red bone marrow, which produces blood cells. So, the texture and function of spongy bone can be compared to that of a sponge.

    Which comes 1st the dermis or epidermis?

    • A.

      Dermis

    • B.

      Epidermis

    Correct Answer
    B. Epidermis
    Explanation
    The epidermis comes first before the dermis. The epidermis is the outermost layer of the skin, providing protection against external factors such as bacteria and UV radiation. It is composed of several layers of cells, including keratinocytes, which produce the protein keratin that gives the skin its strength and waterproofing properties. The dermis, on the other hand, is the second layer of the skin, located beneath the epidermis. It contains blood vessels, nerves, hair follicles, and sweat glands, providing support and nourishment to the epidermis.

    These things are on the tips of your fingers and toes.

    • A.

      Hair follicles

    • B.

      Sweat Glands

    • C.

      Ligaments

    • D.

      Nails

    Correct Answer
    D. Nails
    Explanation
    Nails are located at the tips of both fingers and toes. They are made up of a protein called keratin and are attached to the nail bed, which is rich in blood vessels and nerves. Nails serve multiple purposes, including protecting the fingertips and toes, providing support for the fingers while gripping objects, and enhancing the sensitivity of the fingertips. Additionally, nails can also be used for self-expression and personal grooming.

    Rate this question:

  • 6. 

    This is a type of joint.

    • A.

      Ball and socket

    • B.

      Pivit

    • C.

      Sliding

    • D.

      All of the above

    Correct Answer
    D. All of the above
    Explanation
    The correct answer is "All of the above" because all three options mentioned - ball and socket, pivot, and sliding - are types of joints. A ball and socket joint allows for a wide range of movement in multiple directions, a pivot joint allows for rotational movement around a central axis, and a sliding joint allows for smooth sliding or gliding motion between two surfaces. Therefore, all three options are valid types of joints.

    What do endons join together?

    • A.

      Muscles and Skin

    • B.

      Muscles to Bones

    • C.

      Bones to other bones

    • D.

      All of the above

    Correct Answer
    B. Muscles to Bones
    Explanation
    Endons join muscles to bones. This is the correct answer because endons are connective tissues that attach muscles to bones, allowing for movement and stability. They play a crucial role in the functioning of the musculoskeletal system by transmitting the force generated by muscles to the bones, enabling us to perform various movements and actions.

    The bodies 1st line of defense is..?

    • A.

      Hair Follicles

    • B.

      Synovial Fluid

    • C.

      Nails

    • D.

      Skin

    Correct Answer
    D. Skin
    Explanation
    The skin is the body's first line of defense because it acts as a physical barrier between the internal organs and the external environment. It helps to prevent the entry of pathogens, toxins, and other harmful substances into the body. The skin also contains sweat glands that produce sweat, which helps to cool down the body and flush out toxins. Additionally, the skin has antimicrobial properties that can kill or inhibit the growth of certain bacteria and fungi, further protecting the body from infections.

    Rate this question:

  • 9. 

    Sweat Glands do what?

    • A.

      Release perspiration externally through pores to help regulate body temperature.

    • B.

      Help the body breathe

    • C.

      Nothing

    • D.

      Pores where hair come out

    Correct Answer
    A. Release perspiration externally through pores to help regulate body temperature.
    Explanation
    Sweat glands release perspiration externally through pores to help regulate body temperature. Perspiration, or sweat, is produced by the sweat glands and is released through the pores on the skin. This process helps to cool down the body when it becomes overheated.

    Which is responsible for bone growth and change?

    • A.

      Osteocytes

    • B.

      Tendons

    • C.

      Skin

    • D.

      Muscles

    Correct Answer
    A. Osteocytes
    Explanation
    Osteocytes are responsible for bone growth and change. Osteocytes are the most common type of bone cell and are found within the bone tissue. They play a crucial role in bone remodeling, which involves the continuous process of bone formation and resorption. Osteocytes help regulate the balance between bone formation and breakdown by secreting signaling molecules that control the activity of other bone cells. They also contribute to the maintenance of bone density and strength. Therefore, osteocytes are essential for bone growth and the ability of bones to adapt and respond to mechanical stress.
