Verified step by step guidance
1
Understand the term 'diploë' in the context of anatomy. It refers to a specific structure found in the cranial bones.
Recall that cranial bones consist of three layers: the outer compact bone layer, the inner compact bone layer, and the spongy bone layer in between.
The spongy bone layer between the inner and outer compact layers of cranial bones is called 'diploë.' This structure provides strength while reducing the weight of the skull.
Eliminate the incorrect options: 'membrane covering the lungs' refers to the pleura, 'outermost layer of the skin' refers to the epidermis, and 'cartilage found at the ends of long bones' refers to articular cartilage.
Conclude that the correct answer is: 'spongy bone layer between the inner and outer tables of the cranial bones.'
