As a whole, skeletal dysplasias are not common. They affect one in every 4,000-5,000 births, although the incidence may be higher since the symptoms may not manifest until early childhood, when short stature, joint abnormalities or other complications arise.
Role of Hormones in the Body. Hormones play a role in nearly every aspect of the bodyâs day to day functioning. For example, they regulate sexual functioning, menstruation, pregnancy, bone health, and the bodyâs overall mood and emotions.
Hormones act as chemical messengers that are released into the blood stream to act on an organ in another part of the body. Although hormones reach all parts of the body, only target cells with compatible receptors are equipted to respond. Over 50 hormones have been identified in humans and other vertebrates.
