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.
Pairs of skeletal parts |
Category |
Humerus ulna |
Appendicular skeleton |
Malleus and stapes |
Ear ossicles |
Sternum and Ribs |
Axial skeleton |
Clavicle and Glenoid cavity |
Pelvic girdle |
The non-matching pair is:
Option 4) Clavicle and Glenoid cavity
The clavicle is indeed part of the appendicular skeleton, specifically the pectoral girdle, and the glenoid cavity is part of the scapula, also belonging to the appendicular skeleton. Therefore, this pair is correctly matched.
Option 1) Humerus and ulna as part of the appendicular skeleton is also a correct match.
Option 2) Malleus and stapes as ear ossicles is a correct match. Ear ossicles are indeed part of the axial skeleton.
Option 3) Sternum and ribs as part of the axial skeleton is also a correct match.
