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

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.
Hormones are usually transported through and affect only cells with?
specific hormone receptors on their surface, allowing for targeted signaling. This ensures that hormones act only on cells that are equipped to respond to their specific signals, optimizing the cellular response to hormonal stimuli and maintaining proper physiological balance.
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 definition of a target cell and why are all cells not considered target cells for all hormones?
A target cell is a specific cell that has receptors for a particular hormone, allowing it to respond to that hormone's signals. Not all cells are considered target cells for all hormones because each hormone is designed to interact with specific receptors on specific cells, leading to specific responses in the body. This specificity ensures that hormones only affect the cells that are meant to respond to them, maintaining the body's balance and regulation.
What determines what cell a hormone will effect?
The target receptor proteins of cells will cause them to affected by a specific protein. These cells are also called "target" cells. Hormones flow via the bloodstream throughout the entire body, but they only affect their specific "target" 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 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 systems and endocrine the system different?
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.
