Anatomy Case

A.

Gigantism is abnormally large growth due to an excess of growth hormone during childhood, before the bone growth plates have closed

* His height will be above average.( http://revues-eco.refer.org/BSLEA/index.php?id=278 )

* B. He can just be a late bloomer. What is constitutional growth delay?

Constitutional growth delay is the medical term for late bloomers. These individuals are healthy and reach normal adult heights, but grow later than other children. (http://www.chop.edu/service/growth-center-diagnostic-and-research/frequently-asked-questions-about-childhood-growth-height.html )

* D. Based on what I know, since girls hit puberty earlier than guys tha also means that they stop growing earlier. Whereas guys hit puberty at a later age they also stop growing around their 19 and 20ish.

Topic 4:

* Part A:

Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone and to prevent hypocalcemic tetany. It is also needed for bone growth and bone remodeling by osteoblasts and osteoclasts [1,2]. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults [1]. Together with calcium, vitamin D also helps protect older adults from osteoporosis. http://ods.od.nih.gov/factsheets/VitaminD-HealthProfessional/

* Bones are fail, assuming that they are light(weight) because Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Vitamin D sufficiency prevents rickets in children and osteomalacia in adults

* (this I just added so you can see it for info and backing up your question on “How might this affect Markus’s bone density”). The lower your bone density, the greater your risk of breaking a bone. A bone density test can help you and your healthcare provider:
