Hormones affect specific tissues called?
Hormones work by affecting Target Organs
What are the main target organs for tropic hormones?
The anterior pituitary produces tropic hormones. These hormones include; thyroid-stimulating hormone, luteinizing hormone, adrenocorticotropic hormone, and follicle-stimulating hormone. The hypothalamus controls the release of these hormones.
What are target tissues?
when the chemicals arrive in the right places, the target tissues, they start to do their work. a group of cells that have receptors embedded in the plasma membrane that are complementary in shape to specific hormone molecules. Only these cells will respond to that specific hormone.
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.
What are target cells for releasing hormones in?
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.
What is the target for releasing organs from the hypothalamus?
A) anterior pituitary
How do target organs most often regulate the pituitary gland?
Negative feedback inhibition
Is GnRH's target organ the pituitary gland?
The answer is Anterior Pituitary
What do the hypothalamus and pituitary gland have to do with the endocrine system?
They secrete hormones into the bloodstream and target certain organs. For example, ADH is secreted by the posterior pituitary gland and targets the nephron in the kidneys to absorb more water, making the urine more concentrated.
What does the organs influenced by hormones are called?
They are the target organs. Hormones act on the target organs
Hormones act at specific target organs because these organs contain what specific for the hormone?
target cells
What organ system contains the pituitary gland?
The pituitary gland is located in the base of your brain and helps in maintaining the release of hormones in your body and functioning of things, including blood pressure, body temperature, sexual organs, growth, etc.
Hormones affect specific tissues called?
Hormones work by affecting Target Organs
What organs do lithium target?
kidneys
Where do hormone go?
hormones go to there target cells or target organs
What luteinizing hormone?
the anterior pituitary gland produces LH but its target tissue is the gonads.
How does Target ship to Australia?
Target has a website with an Australian domain, so orders can be dispatched, but are not 'shipped'. Orders for home delivery and Click and Collect are delivered by Australia post from Target's Melbourne warehouse.
