HGH Basics
This three-letter acronym stands for a hormone that plays a key role in growth and metabolism.
What is HGH?
This brain structure releases GHRH to signal the release of HGH.
What is the hypothalamus?
This daily activity is the most important factor in HGH production.
What is sleep?
A child with very low HGH levels may be diagnosed with this condition.
What is dwarfism?
This synthetic substance can be used to treat HGH deficiency.
What is synthetic growth hormone?
HGH is primarily produced in this pea-sized gland located at the base of the brain.
What is the pituitary gland?
This hormone inhibits HGH release when levels are too high.
What is somatostatin?
This kind of physical activity increases HGH due to the body’s need for tissue repair.
What is exercise?
Adults with HGH deficiency may experience increased body fat and a higher risk of this cardiovascular condition.
What is heart disease?
Synthetic HGH is commonly used to help adolescents achieve this physical trait.
What is average height (or a taller height)?
HGH mainly stimulates growth in these two types of tissues.
What are bones and muscles?
This type of feedback loop helps regulate HGH production.
What is a negative-response loop?
This hormone, produced during stress, reduces HGH production.
What is cortisol?
Excessive HGH in childhood leads to this rare condition marked by extreme height.
What is gigantism?
Even people without HGH deficiency may use synthetic HGH for this genetic reason.
What is being genetically predisposed to be short?
Besides growth, HGH also regulates the use of these three macronutrients for energy.
What are fats, proteins, and carbohydrates?
GHRH stands for this full hormone name.
What is Growth Hormone-Releasing Hormone?
Short bursts of this type of exercise are known to cause major spikes in HGH.
What is high-intensity exercise?
This condition occurs when excess HGH starts after bone plates have fused.
What is acromegaly?
Besides helping children grow, synthetic HGH may help adults maintain strength in these three parts of the body.
What are the heart, muscles, and bones?
This other hormone, produced in the liver in response to HGH, promotes cell growth and division.
What is IGF-1 (Insulin-like Growth Factor 1)?
Name both the hormone that stimulates and the one that inhibits HGH production.
What are GHRH and somatostatin?
Name three lifestyle factors that influence HGH production.
What are sleep, exercise, and stress?
Unlike gigantism, acromegaly often affects people of this age group.
What is middle-aged adults (especially men)?
The group was interested in HGH because they had previously studied these two brain structures in middle school biology.
What are the hypothalamus and pituitary gland?
