IX. Bone Development
In embryos this leads to the formation of the bony skeleton.
In adults, it occurs as part of bone remodeling and bone repair.
-Formation of the Bony Skeleton
Before week 8, the human embryonic skeleton is made of fibrous membranes and hyaline cartilage.
After week 8,
Most bones in the body develop via this model.
We’ll follow limb bone development as an example.
-Growth in Bone Length
At puberty, growth in bone length is increased dramatically by the combined activities of growth hormone, thyroid hormone, and the sex hormones.
