What are the effects of thyroid and sex hormones on bone development and growth
Thyroid hormones stimulate replacement of cartilage in the epiphyseal plates of long bones with bone tissue. Sex hormones stimulate ossification of epiphyseal plates and stop bone growth.
What are fontanels; what's their significance?
They permit some movement between the bones so that the developing skull is partially compressible and can change shape for birth. Soft spots on babies head
