Abstract:
This study included 17 401 normal Han urban children aged 1-20 years from five cities in China in 2005. The skeletal maturity scores were assessed by the Tanner-Whitehouse 3 (TW3) method, and the smoothed centiles curves of scores (TW3-Chinese RUS and TW3-Chinese Carpal) were calculated using the LMS method. The skeletal maturity of the Chinese is approximately the same as Europeans in childhood, but the extent of TW3-RUS skeletal maturity advance in puberty and the ages of complete maturity of TW-Carpals are evidently more advanced in the Chinese.

Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Components of the Skeletal System
Bone, or osseous tissue, is a hard connective tissue that forms an internal support structure for the human body. Bones shield vulnerable organs and soft tissue from external forces. For example, the vertebral bones protect and support the spinal cord.
Cartilage, a semi-rigid connective tissue found in regions such as...
