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.
One special group of hormones is the tropic hormones that stimulate the hormone production of other endocrine glands. For example, thyroid-stimulating hormone (TSH) causes growth and increased activity of another endocrine gland, the thyroid, which increases output of thyroid hormones.ormones affect distant cells by binding to specific receptor proteins in the target cell resulting in a change in cell function. When a hormone binds to the receptor, it results in the activation of a signal transduction pathway.
