Document Summary
Wrist and hand bones of a 1 year old are less interconnected than the corresponding skeletal equipment of adolescent: method of dete(cid:272)ti(cid:374)g a (cid:272)hild"s le(cid:448)el of ph(cid:455)si(cid:272)al (cid:373)aturatio(cid:374) is to (cid:454)-ray the wrist and hand.

Variation in physical development: brain and head grow much faster and quicker to reach adult proportions, genitals and other reproductive organs grow slowly throughout childhood and increase in adolescence. Lymph levels (immune system to help fight off diseases etc. ) overshoot adult levels then decrease during adolescence. Individual variations: development of body systems is an uneven/asynchronous process, hence there is still a sizable individual variation in rates ppl grow.
