Hormone are always mention along side with enzyymes. And enzymes are specific in nature so too different hormone can never be produce by the same gland or act on two different target organs
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.
Hormone receptor
A hormone is a chemical, not a cell. They thyroid gland that secretes the thyroid hormone (which is called thyroxin) is composed of cells.
No, it is a neurotransmitter. A hormone, is a compound produced by an endocrine gland and released into the bloodstream. A neurotransmitters are chemicals that transmit signals from a neuron to a target cell across the synapse and most are synthesized at the nerve terminals.
The receptor changes shape and activates a chain reaction that leads to the cell changing its activities.
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
A target cell is a cell in the body that recognizes a hormone's chemical structure. It is a cell to which a hormone binds chemically.
The binding of a hormone to a receptor is the first step. Target cell activation by hormone-receptor interaction depends equally on 3 factors. First the blood levels of the hormone, second ,relative numbers of receptors for that hormone on or in the target cells and the third ,strength of the binding between the hormone cell and the receptors.
Thymine from the thymus gland.
Once a hormone reaches it's target organ or cell, it increases or decreases the action in the organ or cell. This occurs with the metabolism of the hormones and 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.
