target cells
Target Cells
hormones go to there target cells or target organs
receptors
It's target cells
Only target cells respond to hormones because they have a receptor for the hormone. They are the key that fits the lock.
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.

growth hormone GH
In your body, you have certain cells that can receive and process hormones released by your pituitary gland, hypothalamus and other endocrine glands. However, not all cells can receive all hormones. Target cells are cells that have receptors on them for a specific hormone. So a target cell may have a receptor for GH hormone, thus allowing GH to be absorbed by only the target cells with GH receptors.
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.
