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 are another example of chemical signaling. Hormones are proteins or steroids that are produced and released in one part of the body and then travel to another part of the body where they have an effect. Hormones operate by a process called signal transduction.
