|
|
|
The hormone is sent as an electrical signal through the nervous system.
|
|
|
The hormone is secreted externally through ducts.
|
|
|
The gland will secrete the hormone into the blood stream and it will travel to target organ or cell.
|
|
|
It is secreted as mucus and proteins into target cell.

Detailed explanation-1: -Endocrine glands release hormones into the bloodstream. This lets the hormones travel to cells in other parts of the body. The endocrine hormones help control mood, growth and development, the way our organs work, metabolism, and reproduction. The endocrine system regulates how much of each hormone is released.
Detailed explanation-2: -Hormones travel throughout the body, either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell’s activities.
Detailed explanation-3: -The hormones are released into the bloodstream by the pituitary gland and then travel through the blood vessels until they reach the various organs they have an effect on. TSH, for example, stimulates the thyroid gland to increase or reduce the production of thyroid hormones, depending on how much is needed.
Detailed explanation-4: -Hypothalamic releasing and inhibiting hormones are carried directly to the anterior pituitary gland via hypothalamic-hypophyseal portal veins. Specific hypothalamic hormones bind to receptors on specific anterior pituitary cells, modulating the release of the hormone they produce.
Detailed explanation-5: -Hypothalamic releasing and inhibiting hormones travel through a primary capillary plexus to the portal veins, which carry them into the anterior pituitary. Hormones produced by the anterior pituitary (in response to releasing hormones) enter a secondary capillary plexus, and from there drain into the circulation.
