Cushing's syndrome is characterized by the oversecretion of which of the following hormones?

Cushing's syndrome results from the oversecretion of adrenal cortex hormones, primarily glucocorticoids, which include cortisol. This condition can stem from various causes such as a tumor in the pituitary gland (Cushing's disease), an adrenal tumor, or ectopic ACTH production from other cancers. Alongside glucocorticoids, there can also be an excess of mineralocorticoids and androgenic hormones due to the underlying causes affecting the adrenal glands.

The presence of excess glucocorticoids is responsible for most of the manifestations associated with Cushing's syndrome, such as weight gain, hypertension, and changes in glucose metabolism. The involvement of mineralocorticoids can lead to electrolyte imbalances and hypertension, while increased androgen levels may result in symptoms such as hirsutism or menstrual irregularities.

The other options relate to different hormonal imbalances that do not pertain to Cushing's syndrome. Insulin and glucagon are involved in glucose metabolism, while catecholamines, serotonin, and dopamine are neurotransmitters and hormones associated with stress responses and mood. Estrogen, testosterone, and progesterone primarily pertain to reproductive health and are not associated with the characteristic hormone dysregulation seen in Cushing
