The questions

    Show the answer

    Answer: 206

    Eighty axial bones — cranium, vertebral column and thoracic cage — plus 126 appendicular ones in the girdles and limbs.

  2. Where are blood cells manufactured in an adult?

    1. The spleen
    2. The liver
    3. Red marrow in the spongy bone
    4. The dense outer shell of the bone
    Show the answer

    Answer: Red marrow in the spongy bone

    Red marrow fills the lattice of spongy bone — in adults mainly in the vertebrae, sternum, ribs, pelvis and the ends of the femur and humerus.

  3. What type of joint is the hip?

    1. Hinge joint
    2. Pivot joint
    3. Ball-and-socket joint
    4. Saddle joint
    Show the answer

    Answer: Ball-and-socket joint

    A ball-and-socket joint moves on every axis — but the hip's deep socket trades away range to stay stable enough to carry your weight.
