Compact bone 2) What features of the sample on the slide helped you come to this conclusion? Osteon and lamellae are found Station 3: Articulated Skeleton Go to one of the boxes of skeletal bones and using your textbook, lay out the bones in the correct relative locations for an intact skeleton . When you are done, name the labeled bones (1-13) and answer any questions associated with them. Then return the bones to their box. 1) What is the name of the bone labeled “1”? frontal 2) What is the name of the bone labeled “2”? parietal 3) What is the name of the bone labeled “3”? temporal 4) What is the name of the bone labeled “4”? occipital 5) What is the name of the bone labeled “5”? sphenoid 6) What is the name of the bone labeled “6”? humorous What is bone marking “D” called? Head What is bone marking “E” called? Tuberosity What is bone marking “F” called?
