Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone of the skull are joined by fibrous joint.
  2. First vertebra is axis which articulates with the occipital condyles.
  3. The 9th and 10th pairs of ribs are called the floating ribs.
  4. Glenoid cavity is a depression to which the thigh bone articulates.

Answer

(1) Parietal bone and the temporal bone of the skull are joined by fibrous joint.

Solution

As per NCERT, fibrous joints do not allow any movement; the flat skull bones are fused end-to-end by dense fibrous connective tissue in the form of sutures. ⇒ Parietal and temporal bones are joined by a fibrous joint. Option (1) is correct.

⇒ The first vertebra is the atlas (not the axis), and it articulates with the occipital condyles. Option (2) is wrong.

⇒ The 11th and 12th pairs of ribs are not connected ventrally and are called floating ribs. Option (3) is wrong.

⇒ The glenoid cavity of the scapula articulates with the head of the humerus (upper arm bone), not the thigh bone. Option (4) is wrong.

Answer: (1)
