*Technical Question* What are the mechanisms for growth, especially during the teen years?

Question by calloonous: *Technical Question* What are the mechanisms for growth, especially during the teen years?
I am looking for an answer or answers that would relate to human biology, specifically at the cellular level. What hormones are related to bone activities? How are these hormones regulated by the body, age and other environmental factors? Further more, are such mechanisms consistent throughout the "growth" period, commonly known as until age 21? What website or other resources can I research into for this topic?

"Growth is triggered in both boys and girls by increased levels of the sex hormone testosterone. This chemical also triggers the sexual organs to develop. In fact, the relationship between growth of the skeleton and puberty is so strong that a teenager's developmental age can be measured by looking at the maturity of the bones in their hand and wrist."

"Control of Growth

Hormones are chemicals produced by special cells in glands and other organs of the body; most hormones are produced by cells in the endocrine glands. These hormones, which are produced in very small amounts, are released into the bloodstream and travel to the "target organ" or tissue where they exert their effect.

Several hormones are involved in regulating growth. Some act directly on target organs, while others act by triggering the production of other hormones, which activate specific organ functions necessary for growth. This finely tuned system can malfunction in several ways, causing abnormal growth.

The pituitary gland is often called the master gland because it produces several hormones that control the functions of other glands. It is located in the middle of the skull below the part of the brain called the hypothalamus. The pituitary gland has two distinct parts: An anterior (front) lobe and a posterior (rear) lobe. The pituitary gland secretes its hormones in response to chemical messages from the hypothalamus, the part of the brain to which it is connected.

Growth hormone is an anterior pituitary hormone whose main effect is to promote growth of body tissues. Other anterior pituitary hormones affect growth indirectly by working through other glands. These other hormones include:

Thyroid Stimulating Hormone (TSH) - causes the thyroid gland to produce thyroid hormone, which regulates body metabolism and is essential for normal growth.
Adrenocorticotropic Hormone (ACTH) - causes the adrenal glands to produce cortisol (stress hormone) and other hormones that enable the body to respond to stress. Too much cortisol will cause growth failure in a child.
Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) - cause the sex glands (ovaries or testes) to produce sex hormones, which are necessary for adolescent sexual development and the growth spurt that accompanies puberty.
The major hormone produced by the posterior pituitary gland -is called vasopressin, or anti-diuretic hormone (ADH). It controls water output through the kidneys."

hope this helps a little

How much money for a year's supply of human growth hormone?

I want to get taller, or at the very least put on some lean muscle mass. Is there any specific type of HGH that stimulates the pituitary gland enough to make you grow a few inches.

yoghurt, cheese, and boiled chicken. Your bones need phosphorus, calcium, and magnesium while your muscles need water, protein and carbohydrates to grow. Since you are growing taller, both your muscles and bones are getting bigger and longer. Don't waste your money or your health on drugs, alcohol or cigarettes.


Have the hair style that makes you appear taller. In order to appear taller, a hair style should be thin at the sides and higher up top, which can make you appear as much as an inch taller Avoid clothes with horizontal lines. Belts are horizontal so make sure you conceal it in your clothes. Avoid clothes with a tartan or checked pattern. Avoid cuffs that makes your legs appear shorter.

• Wear clothes with vertical lines or striping. Vertical lines or stripping make a person appear thinner, and thinness in turn gives impression of more height.

Wear shoes that will make you appear taller. If you are a female, this should be easy since you can find a lot of female shoes with 2 or 3 inches’ heels. For males, wear shoes with thick soles to add the illusion of height.

To increase your height, it is important that your blood is oxygenated as blood provides nourishment to your bones. Regular breathing will also purify your blood. There are three phases to breathing:

1. Inhaling - take in air into your body through the nose
2. Retaining - hold your breath inside your body
3. Exhaling - blow out air from your body through the mouth

It is during deep sleep that growth hormone does its job of thickening and lengthening your bones. So appropriate sleeping time (not the longer, the better) and correct sleeping posture is very important for your body to grow. Sleep is defined as a natural periodic state of rest for the mind and body, in which the eyes usually close and
consciousness is completely or partially lost, so that there is a
decrease in bodily movement and responsiveness to external stimuli.

During deep sleep, growth hormone produced by your pituitary gland is released into your blood stream and travel through your body and causes the thickening and lengthening of your bones. Therefore, you should achieve "deep level" sleep on a daily basis in order to
coordinate your affords of exercises and proper diet. The following are some helpful tips on how to easily achieve deep level sleep.

Sleep in a comfortable and firm mattress.
Sleep in a room that is dark, quiet and fresh smelling.
Sleep with clean, soft, and comfortable clothes.
Keep your hands and feet warm. Scientific studies have shown that warm hands and feet will help induce REM (rapid eye movement) deep sleep. Cold hands and feet will keep you from deep sleep.
Drink a big glass of water before going to bed and when you wake up; this will help clean out your system.
Practice total relaxation and deep breathing for a few minutes before you go to bed.
Relax from head to toe. Close your eyes and relax every part of your body.
Maintain a habit of sleeping at the same time everyday, including weekends.
Sleep on your back with a flat pillow under your knees. This will align your spine properly and prevent any back aches caused by sleeping in a bent position.

Undoubtedly, the quality, quantity, and type of food we eat affect our height, growth, and health. We cannot emphasize enough how important your food intake is in determining how much growth you can possibly obtain. The types of food you eat will either improve or decrease your growth potential.

After careful consideration and research, the daily content of protein, carbohydrates, fats and water can be achieved if the following items were taken regularly.

Carrots Fish Liver
Egg Yolk Beef Red Meat
Milk Cheese Apples
Green Vegetables Potatoes Nuts
Yellow Vegetables Almonds Bananas
Peanuts Chicken Beans
Peas Salt 6-8 glasses of water per day

If you eat a lot of peanut butter, your height will not necessarily stop. Neither does masturbation stop height.
What might stop you from growing is smoking, drugs, alcohol, lack of sleep, stress, digestive problems, or lack of exercise.

Well you can't really force yourself to get taller, but it definitely helps to stretch! Stretching in the morning and before you go to bed will help you get taller :)
