What name is given to regions that are receptive to hormones?
Target tissues or target cells are regions that are receptive to hormones. These tissues have specific receptors that bind with the hormones and trigger a response within the cell.
What are the structures that allow hormones to bind to their target cells?
Hormones bind to specific protein receptors on the surface or inside target cells. These receptors are typically found on the cell membrane or in the cytoplasm. Once the hormone binds to its receptor, it triggers a signaling cascade that leads to specific cellular responses.
What type of cell-to-cell signaling to hormones exert?
Hormones exert long-range cell signaling, where they are released into the bloodstream by endocrine glands and travel to target cells in distant parts of the body to elicit a response. Hormones bind to specific receptors on target cells to trigger signaling cascades that regulate various physiological processes.
What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
Where is the receptor for cortisol found?
Receptors of protein hormones are present in plasma membrane but for steroid hormones no membrane receptors are needed as they can enter cell membrane , mobile receptors pic steroid hormones from cell membrane and carry them to nucleus .
The receptors for thyroid hormones are found?
within the nucleus of the target cell
The receptors for catecholamine and polypeptide hormones are found?
on the outer surface of the target cell
What do you call the cell that accepts specific hormones?
Target cell
What is the difference between an endocrine cell and a target cell?
the endocrine cell has a jelly like substance and so so it drops off it in the blood vessel and so target cells make hormones in the blood vessel to bind into thereceptor on a target cell sometimes a target cell is very close or far away
What are hormones carried in to their target cell?
Hormones are typically carried in the bloodstream to their target cells. Once the hormone reaches its target cell, it binds to specific receptors located on the cell membrane or within the cell, triggering a cellular response.
What name is given to regions that are receptive to hormones?
Target tissues or target cells are regions that are receptive to hormones. These tissues have specific receptors that bind with the hormones and trigger a response within the cell.

What hormones can enter the target cell and bind to receptors in the nucleus?
Steroid hormones, such as estrogen and testosterone, are able to enter the target cell and bind to receptors in the nucleus. These hormones are lipid-soluble, allowing them to pass through the cell membrane and directly interact with nuclear receptors to regulate gene transcription.
How does a hormone identify its target?
Only target cells have receptors inside cytoplazm (for steroid hormones) or on cell membrane (for protein hormones) that make the hormone active.
What is the difference between direct and tropic hormones in terms of their mode of action on target organs?
Direct hormones act directly on target organs by binding to specific receptors on the cell surface, triggering a response within the cell. Tropic hormones, on the other hand, act indirectly by stimulating the release of other hormones from endocrine glands, which then affect the target organs.
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 type of cell-to-cell signaling to hormones exert?
Hormones exert long-range cell signaling, where they are released into the bloodstream by endocrine glands and travel to target cells in distant parts of the body to elicit a response. Hormones bind to specific receptors on target cells to trigger signaling cascades that regulate various physiological processes.
