Analyze the function of bones in providing shape

Bones form the structural framework of the body, which directly determines the shape and support of major anatomical regions.

Evaluate each option

• Legs: Supported by long bones (femur, tibia, fibula) that define their shape and length.
• Head: Shaped by the cranial and facial bones of the skull.
• Trunk: Shaped by the vertebral column, ribs, and sternum.
• Toenails: Composed of keratinized epidermal cells, containing no bones to determine their shape.
