Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.

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 determines if a cell is a target cell for a particular hormone?
If the signal molecule is able to fit through the cell membrane, it will bind to an intracellular receptor, if it cannot pass through the cell membrane, it will bind to an external membrane-surface receptor.
How are the nervous system and the endocrine system different?
The nervous system can affect only nearby cells. APEX
Hormones are usually transported through and affect only cells with?
Local hormones are usually transported through cells and only affect the cells that are in that locality. They have the ability to affect all cells that they come into close contact with.
Is luteinizing hormone produced only during the luteal phase of the menstrual cycle?
No, luteinizing hormone is produced by the testicular interstitial cells
Why are hormones able to affect only certain cells and not other cells?
Because they only activate target cells that have special receptors that only work when that specific hormone attaches to it.

Why does hormone act only on specific cell types in a organism and not others?
Hormones can only be detected by cells that have the specific receptor which binds to the hormone. This means that the hormone only acts on the cells with its receptor and the other cells do not respond.
How do you some hormones affect only certain cells in the body but not others?
These cells have specific types of receptors on their membranes.
What determines if a cell is a target cell for a particular hormone?
If the signal molecule is able to fit through the cell membrane, it will bind to an intracellular receptor, if it cannot pass through the cell membrane, it will bind to an external membrane-surface receptor.
Why do only target cells respond to the hormone while the others are unaffected?
Only target cells respond to hormones because they have a receptor for the hormone. They are the key that fits the lock.
What are target cells.?
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.
How are the nervous system and the endocrine systems different?
The endocrine system affects cells with certain receptors . The nervous system can affect only nearby cells

The endocrine system affects cells with certain receptors . The nervous system can affect only nearby cells

If hormones travel in the bloodstream why don't all tissues respond to all hormones?
The tissue/cells need a receptor that can interact with that hormone in order to respond to it. This receptor may be on a cell membrane, inside the cell, or even inside the nucleus (in the case of steroid hormones, for example.) Like many organic chemicals in the body, they have structures which result in certain parts of the molecule being presented to cells (active sites). Because cells and tissue have different structures as well, only certain cells will react to the presence of a particular hormone. Many hormones have antagonist hormones that cause an opposite effect. This helps control negative feedback when the target organ's hormone levels are too high.
Hormones are usually transported through and affect only cells with?
Local hormones are usually transported through cells and only affect the cells that are in that locality. They have the ability to affect all cells that they come into close contact with.
