barbour outlet Understanding The Production & Rele |
|
Simply saying, human growth [link widoczny dla zalogowanych] hormone (HGH) is secreted by [link widoczny dla zalogowanych] the pituitary gland when a special part of the brain called hypothalamus sends special "release signals" to the pituitary gland. However, the process is much more detailed than this. Therefore, to understand the production and release of HGH, it is important to first understand the role and connection between hypothalamus and pituitary gland.
Hypothalamus: Hypothalamus is the main primitive part of the brain that [link widoczny dla zalogowanych] sends either stimulating or inhibiting hormones to the pituitary. Acting as a "thermostat" in your house, hypothalamus always manages the changing shifts in hormone production and secretion within the body. For the purpose of regulation of production and secretion of hgh, [link widoczny dla zalogowanych] the hypothalamus [link widoczny dla zalogowanych] produces two hormones that help in the overall process:
Growth hormone stimulating hormone (GHRH): tells the pituitary gland to secrete more HGH.
Growth Hormone Inhibiting Hormone (GHIH) tells the pituitary gland to stop producing more HGH.
Pituitary: [link widoczny dla zalogowanych] The pituitary is known as our "master gland." It sits at the base of our brain and communicates directly with the [link widoczny dla zalogowanych] hypothalamus by special nerves and blood vessels. Releasing hormones travel from the hypothalamus to the pituitary and stimulate the formation and release of pituitary hormones into our circulatory system. The pituitary hormones exert their effects on many of our organs, such as the thyroid, adrenal glands, testicles, ovaries, and breasts.
There are five basic pituitary hormones:
Thyroid Stimulating Hormone (TSH)
Adrenocorticotropic Hormone (ACTH)
Follicle Stimulating Hormone (FSH)
Luteinizing Hormone (LH)
Human Growth Hormone (HGH) for adult deficiency
These pituitary hormones act like air traffic controllers, surveying the scene, determining what is needed, and [link widoczny dla zalogowanych] then telling the organs when to release their hormones. Out of all the various pituitary hormones, HGH [link widoczny dla zalogowanych] has the most universal action, ultimately affecting every cell of the body.
Understanding the process in a simplified way…
The hypothalamus portion of the brain, activated by nerve signals from elsewhere in the brain, secretes releasing hormones, [link widoczny dla zalogowanych] which in turn cause the pituitary to release its hormones. Out of all the various pituitary hormones, HGH has the most universal action, ultimately affecting every cell of the body.
GH secretion occurs in a pulsatile (short, concentrated secretion) and sporadic manner i.e. it is [link widoczny dla zalogowanych] secreted in pulses (bursts) by the pituitary gland. These pulses vary between 6 and 12 per day, with the largest pulse secreted about an hour after the onset of night-time sleep (around midnight for most people). While the hormone is secreted throughout a person's lifetime, its production and secretion declines significantly as the person ages.
Frequency & amount Of HGH secretion
In general, human growth hormone (HGH) secretion follows a circadian rhythm and is secreted in 6-12 discrete pulses per day, Amount of HGH secretion
In numerical values, we produce on a daily basis about 500 micrograms at 20 years of age, 200 [link widoczny dla zalogowanych] micrograms at 40 years, and 25 micrograms at 80 years old. Once the pituitary gland releases its squirts of growth hormone into the bloodstream it is there only for a couple of minutes. The liver takes in the HGH and converts it into growth factors, particularly the important growth factor called IGF-1 (insulin-like growth factor-1).
