Final answer:
Excessive development, often referred to as hypersecretion, leads to various disorders such as gigantism or acromegaly when related to growth hormone, and can cause symptoms like hypertonia, hypertrophy, and developmental delays depending on the substance involved.
Step-by-step explanation:
Excessive (more than normal) development is referred to in various contexts within biology and medicine. For instance, hypersecretion involves the secretion of more than the normal amount of a substance, such as a hormone by an endocrine gland. Disorders can arise due to such excessive production. For example, the excess production of growth hormone (GH) in childhood leads to a condition known as gigantism, characterized by significantly long hands and legs. Conversely, when there is an excessive production of GH after full skeletal growth, the result is acromegaly, where individuals may exhibit a broadened skull and thickened soft tissues.
Other terms associated with abnormally high development include hypertonia, which is an abnormally high muscle tone; hypertrophy, the addition of structural proteins to muscle fibers; and hyperplasia, an increase in the number of cells. These conditions can cause a range of symptoms, such as abnormal growth patterns, developmental delays, and distinctive facial appearances.
Moreover, excessive production of certain hormones leads to specific manifestations. For instance, too much prolactin production can cause amenorrhea, galactorrhea, and breast enlargement. As a general insight into the importance of maintaining hormonal balance, excess production often stimulates actions related to growth and blood glucose levels, reflecting the interconnectedness of endocrine functions across various bodily systems.
