36. A. Long bones
In long bones, the diaphysis is seperated from the epiphysis by an epiphyseal plateI.
37. Bone growth in length occurs at the epiphyseal plate in
B. Long bones
The epiphyseal plate is the area of growth in a long bone.
38. D. epiphyseal plate, it allows the diaphysis of the bone to increase in length until early childhood, as well as shaping the articular surfaces.
39. B. lacunae
Each lacuna is occupied during life by a branched cell, termed an osteocyte, bone-cell or bone-corpuscle. Lacunae are connected to one another by small canals called canaliculi.
