Which of the following bones is not part of the lower appendicular skeleton?

• A. Ilium
• B. Scapula
• C. Patella
• D. Tibia

Answer: (B)

The scapula is the correct answer because it is part of the upper appendicular skeleton, not the lower. The upper appendicular skeleton comprises the bones of the shoulders and arms, including the scapula (shoulder blade) and its associated structures. On the other hand, the lower appendicular skeleton includes bones such as the ilium, patella, and tibia, which are all integral to the pelvis and lower limb structure. Understanding the classification of bones into appendicular and axial categories is essential for anatomy students, as it helps clarify the structure and function of the skeletal system.
