Final answer:
The incorrect statement about osteogenesis is that growth in bone length continues after the epiphyseal plate has closed. Bone length growth ceases once the epiphyseal plates ossify and are replaced by an epiphyseal line. Growth in bone diameter continues through subperiosteal intramembranous ossification.
Step-by-step explanation:
The false statement about osteogenesis is: growth in bone length continues after the closure of the epiphysis. This is because the growth in the length of bones is due to the activity of the epiphyseal plate, which is a layer of cartilage that allows for the continued lengthwise growth of the bone. During endochondral ossification, which occurs after birth, the epiphyses develop secondary ossification centers and the cartilage begins to be replaced by bone. The epiphyseal plates are present until early adulthood and once they close (ossify completely), longitudinal growth of the bones stops and is replaced by an epiphyseal line.
Growth in bone diameter is a different process known as appositional growth, which involves the addition of new bone tissue on the outside of existing bone, through the activity of cells beneath the periosteum, by a process called subperiosteal intramembranous ossification.
