Cushing's syndrome is the result of the excessive production of corticosteroids by the adrenal glands. An overproduction of corticotropin (ACTH) - the hormone that controls the adrenal gland - by the pituitary gland, which stimulates the adrenal glands to produce corticosteroids, may be one cause. It is called Cushing's disease and the result of ACTH-secreting pituitary adenoma. Alt.

Imperfection, flaw, or deficiency. That which is subject to a defect is missing a requisite element and, therefore, is not legally binding. Defective Service of Process, for example, is service that does not comply with a procedural or jurisdictional requirement. A defective will is one that has not been properly drawn up, has been obtained by unlawful means, or does not comply with a particular law.
