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.
Each hormone affects certain cells in your body, known as target cells. Such cells have specific receptors on which the hormone attaches itself to transmit the signals. An example of a hormonal protein is insulin, which is secreted by the pancreas to regulate the levels of blood sugar in your body.
