    The two main divisions of the skeletal systems are the

    • Carpals and humerus

    • Radius and ulina

    • Clavicle and Femur

    • Axial and appendicular

    Correct Answer
    A. Axial and appendicular
    Explanation
    The correct answer is axial and appendicular. The skeletal system is divided into two main divisions: the axial skeleton and the appendicular skeleton. The axial skeleton includes the bones of the skull, vertebral column, and rib cage, which provide support and protection for the vital organs. The appendicular skeleton includes the bones of the upper and lower limbs, as well as the pectoral and pelvic girdles, which are involved in movement and locomotion.

    • Sesamoid

    • Long

    • Sutural or wormian

    • Irregular

    Correct Answer
    A. Sutural or wormian
    Explanation
    The classification "sutural or wormian" refers to the bones that are found within the sutures or joints between the bones of the skull. These bones are small and irregularly shaped, and they are not present in every individual. They are considered accessory bones and are formed due to the incomplete fusion of the skull bones.

    Carpals and tarsals are which bone classification?

    • Flat

    • Long

    • Short

    • Irregular

    Correct Answer
    A. Short
    Explanation
    Carpals and tarsals are classified as short bones because they are approximately equal in length and width. Short bones provide stability and support, and they are found in areas where fine movements are required, such as the wrists and ankles. They are composed of a thin layer of compact bone surrounding a spongy, trabecular bone. The shape and structure of short bones allow for a greater range of motion and flexibility compared to other bone classifications.

    Small rounded process

    • Sulcus

    • Trochanter

    • Tubercle

    • Tuberosity

    Correct Answer
    A. Tubercle
    Explanation
    A tubercle is a small rounded process on a bone. It is a small bump or projection that serves as an attachment point for ligaments or tendons. It is different from a tuberosity, which is a larger, rougher projection on a bone. A sulcus is a groove or furrow on a bone, while a trochanter is a large, prominent process found only on the femur bone. Therefore, the correct answer is tubercle, as it fits the description of a small rounded process.

  • 17. 

    Either of the two boney projections below the neck or femur

    • Meatus

    • Tuberosity

    • Tubercle

    • Trochanter

    Correct Answer
    A. Trochanter
    Explanation
    The trochanter is a boney projection found either below the neck or the femur. It is a large, roughened prominence that serves as an attachment point for muscles. The other options, meatus, tuberosity, and tubercle, do not accurately describe the boney projections below the neck or femur. A meatus refers to a canal or opening, while a tuberosity is a rounded prominence and a tubercle is a small, rounded projection. Therefore, the correct answer is trochanter.
