in the hypothalamus is what my book says:)
.............from what I have read the releasing hormones originate in the hypothalamus, but the target cells are found in the anterior pituitary gland.

∙ 11y agodepends on the hormone, each hormone binds to a specific receptor on the cell membrane of its target cell/cells, e.g. insulin binds to hormone-sensitive receptors on the mebranes of muscle cellas, adipocyte cells, liver cells. where as antidiuretic hormone binds only to cells of the kidney rebsorption tubules.

Are hormones target molecules or signal molecules?
Hormones affect target cells because target cells have receptors that bind with certain hormones (they're specific). If a cell does not have a receptor then it is not affected by hormones. Target cells (which do have the receptor for a particular hormone) would be affected by the hormone.
What is the method that tropic and nontropic hormones produce response?
Tropic hormones stimulate endocrine glands to release another hormone which affects the target cells whereas non-tropic hormones act directly on the target cells.
explain why hormones in the bloodstream are able only to affect target cells/organs and not other cells/organs?
Hormones in the bloodstream are able to affect target cells/organs and not other cells/organs because of selective permeability. This means that hormones are only able to pass through the cell membrane of certain cells and organs, and not through the cell membrane of other cells and organs. The cell membrane of the target cells and organs are specialized to allow the hormones to pass through, while the cell membrane of other cells and organs are not specialized and are therefore impermeable to the hormones. This is due to the presence of receptor proteins on the cell membrane of the target cells and organs. These receptor proteins can bind to the hormones and facilitate their entry into the cell. Since these receptor proteins are not present on the cell membrane of other cells and organs, the hormones are unable to bind to them and therefore unable to cross the cell membrane. In addition, hormones can be broken down by enzymes in the bloodstream, which means they can’t reach their target cells and organs if they are exposed to the enzymes. This further ensures that hormones only affect the target cells and organs, and not other cells and organs. In summary, hormones in the bloodstream are able to affect target cells and organs and not other cells and organs because of selective permeability and the presence of receptor proteins on the cell membrane of the target cells and organs. Other cells and organs do not have these specialized receptor proteins and therefore cannot be affected by the hormones.
How does protein hormones reach their target cells?
Usually in blood plasma, which carries them to their target cells. They 'recognize' these cells based on receptors on the cell membranes to which they bind.
The pulsatile secretion of hormones?
is needed to prevent the downregulation of target cells
What are the structures that allow hormones to bind to their target cells?
Receptors allow hormones to bind to their target cells.
Liver cells respond to growth hormones by releasing hormones called?
somatomedins
What hormones has more target cells in the body than any of the others Antidiuretic hormone corticotropin-releasing hormone growth hormone or oxytocin?
oxytocin
What hormones has more target cells in the body than any of the others Antidiuretic hormone corticotropin releasing hormone growth hormone or oxytocin?
growth hormone
How do hormones interact with target cells?
penis
Where do hormone go?
hormones go to there target cells or target organs
What are hormones transported to?
Hormones are transported to target cells, which are cells in another part of the body where the hormone will have an effect.
What Peripheral cells sensitive to the presence of hormones are called?
Target Cells

Cytotoxic t cells destroy their target cells by releasing substances that alter?
cell membrane
