    The vertabrae in the ________ all articulate with ribs.

    • Cervical

    • Thoracic

    • Lumbar

    • Sacral

    Correct Answer
    A. Thoracic
    Explanation
    The vertebrae in the thoracic region of the spine all articulate with ribs. This means that each thoracic vertebra has a pair of ribs attached to it, forming a protective cage around the vital organs in the chest. The articulation allows for movement and flexibility in the upper body, while also providing support and stability. The cervical, lumbar, and sacral regions of the spine do not have this characteristic, as the vertebrae in these regions do not articulate with ribs.

    Narrow pubic arch - less than 90 degrees =

    • Male

    • Female

    • Dog

    Correct Answer
    A. Male
    Explanation
    A narrow pubic arch with less than 90 degrees is typically found in males. This is because the shape of the pelvis in males is generally narrower and more V-shaped, allowing for a narrower pubic arch. In females, the pubic arch is wider and more U-shaped to accommodate childbirth. While dogs also have a pubic arch, their anatomy differs from humans, and a narrow pubic arch is not necessarily indicative of their gender.

    The C1 vertebra is also known as the atlas. The atlas is the first vertebra in the cervical spine and is responsible for supporting the weight of the head. It is named after the Greek mythological figure Atlas, who carried the weight of the world on his shoulders. The atlas is unique in that it does not have a body like the other vertebrae, but instead consists of a ring-like structure that allows for the movement of the head.

    Rate this question:

  • 25. 

    __________ are those that do not attach directly to the sternum, but to the cartilage of another rib.

    • True ribs

    • False ribs

    • Floating ribs

    Correct Answer
    A. False ribs
    Explanation
    False ribs are those that do not attach directly to the sternum, but to the cartilage of another rib. Unlike true ribs, which attach directly to the sternum, false ribs have their cartilage attached to the cartilage of the rib above them. This allows for more flexibility in the ribcage and helps with the expansion of the chest during breathing. Floating ribs, on the other hand, are the last two pairs of false ribs that do not attach to the sternum or any other rib, giving them a floating-like appearance.

    Hyperlordosis is an excess curvature of a _________ curve.

    • Primary

    • Secondary

    • Tertiary

    Correct Answer
    A. Secondary
    Explanation
    Hyperlordosis is an excess curvature of the secondary curve. The human spine has three natural curves: primary, secondary, and tertiary. The primary curve is present at birth and is located in the thoracic region. The secondary curve develops as a child begins to lift their head and crawl, and it is located in the cervical region. The tertiary curve develops as a child learns to walk and stand, and it is located in the lumbar region. Hyperlordosis specifically refers to an excessive inward curvature of the secondary curve in the cervical region, leading to an exaggerated arch in the lower back.
