Which hormone and condition are mismatched?

a. insufficient ADH—diabetes insipidis
b. too much ADH—diabetes mellitus
c. insufficient growth hormone—pituitary dwarfism
d. too much growth hormone in adults—acromegaly
e. too much growth hormone in children—gigantism

Key Concepts

Gigantism

Gigantism is a condition caused by excess GH secretion during childhood before the epiphyseal growth plates have closed, resulting in abnormally tall stature and accelerated physical growth.

Acromegaly

Acromegaly is a disorder caused by excess GH in adults, typically after the closure of growth plates, leading to abnormal growth of the hands, feet, facial features, and internal organs.

Pituitary Dwarfism

Pituitary Dwarfism is a condition resulting from a deficiency in growth hormone during childhood, leading to significantly reduced growth and short stature. This condition highlights the importance of GH in normal developmental processes.

Growth Hormone (GH)

Growth Hormone is produced by the pituitary gland and plays a critical role in stimulating growth, cell reproduction, and regeneration in the body. The level of GH influences various growth-related conditions based on whether it is deficient or in excess.

Antidiuretic Hormone (ADH)

ADH is a hormone that helps regulate water balance in the body by controlling the amount of water reabsorbed by the kidneys. Its proper regulation is essential for maintaining fluid homeostasis and osmolarity in the body.

Diabetes Insipidus

Diabetes Insipidus is a condition characterized by an inability to concentrate urine, often due to insufficient ADH or resistance to its effects. This results in the excretion of large volumes of dilute urine and can lead to dehydration.

Hormones

Hormones are chemical messengers produced by glands in the endocrine system. They travel through the bloodstream to target tissues, where they regulate various bodily functions including growth, metabolism, and water balance.

Diabetes Mellitus

Diabetes Mellitus is a metabolic disorder primarily associated with abnormalities in insulin production or action, leading to elevated blood glucose levels. It is fundamentally a disorder of carbohydrate metabolism, not of water regulation.
