Answer 5

what about length and width

Answer 6

As an individual's height increases, the bone must increase its diameter, and this is achieved by new bone being laid down by the osteogenic layer of the periosteum. This is intramembranous ossification that does not involve prior cartilage formation. However, the shafts of long bones do not increase in width significantly, as this would increase skeletal mass excessively, because there is resorption of bone on the inner (endosteal) surface by bone resorbing cells, the osteoclasts. This leads to an increase in the size of the marrow cavity with age, and means that the cortical bone of an adult's femur, for example, is not the same bone that existed in childhood. The cycle of bone resorption and formation is bone remodelling, and in the growing skeleton this is often described as 'structural modelling'. Remodelling of bone is a dynamic process that continues throughout life with losses from osteoclastic bone resorption made good by bone formation.
