Q. Which one of the following is the correct description of a certain part of a normal human skeleton?
A) Parietal bone and the temporal bone of the skull are joined by fibrous joint
B) First vertebra is axis which articulates with the occipital condyles
C) The 9th and 10th pairs of ribs are called the floating ribs
D) Glenoid cavity is a depression to which the thigh bone articulates
Explanation
[Solution from source] Skull bones such as the parietal and temporal are joined by sutures, which are fibrous, immovable joints. The first vertebra is the atlas (not the axis), the floating ribs are the 11th and 12th pairs, and the glenoid cavity takes the head of the humerus, whereas the femur fits into the acetabulum.
