There are certain receptors for some specific hormones on the cell membranes of the target cells of the hormone. They are activated by the hormone and combine with it to form a complex that undergoes a series of receptor mediated reactiions to perform the particular function inside the cell. Some hormones pass through the cell membrane and interact with the receptors present on the membrane of cell organelles. Some hormones like thyroxine interact directly with the nucleus and trigger metabolic enzyme synthesis for increasing BMR
The presence of the appropriate receptors on the cells of the target tissue or organ
Nervous tissue would be the most responsive. For example, the eyes respond to changing light intensity, blood flow, hair orientation and lung bronchioles all respond to changing temperature. The skin (melanocytes) also respond to UV radiation over time.
testosterone
Mesenchymal Stem Cells respond to injury by diving to assist in connective tissue repair.
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.
promotes the entry of glucose and amino acids into tissue cells
Leptin is a hormone released by adipose tissue.
Prostaglandins are the group of hormones referred to as tissue hormones.
A tissue becomes a target tissue when it is affected or stimulated by a specific amino acid. The target tissue has the appropriate receptors to make it susceptible to the hormone.
Target tissue
The main primary target tissue of the Parathyroid hormone is the bone, but the kidneys are a target as well.
Nervous tissue would be the most responsive. For example, the eyes respond to changing light intensity, blood flow, hair orientation and lung bronchioles all respond to changing temperature. The skin (melanocytes) also respond to UV radiation over time.

That hormone is vitamin D.
