Q. Three of the following pairs of the human skeletal parts are correctly matched with their respective inclusive skeletal category and one pair is not matched. Identify the non-matching pair.
A) Humerus and ulna – Appendicular skeleton
B) Malleus and stapes – Ear ossicles
C) Sternum and ribs – Axial skeleton
D) Clavicle and glenoid cavity – Pelvic girdle
Explanation
[Solution from source] The clavicle and the glenoid cavity (on the scapula) belong to the pectoral girdle, not the pelvic girdle, so this pair is mismatched. Humerus and ulna are limb bones of the appendicular skeleton, malleus and stapes are ear ossicles, and sternum and ribs belong to the axial skeleton. Answer (4).
