Uwill get 50 i need this answer by tomorrow! how are hormone levels regulated?

Hormonal regulation of hormone release involves a hormone binding to its receptor on an endocrine cell to regulate hormonal secretion. A hormone that regulates hormone secretion is called a tropic hormone. Tropic hormones may also stimulate proliferation of endocrine cells.

insulin causes blood glucose levels to drop, which signals the pancreas to stop producing insulin in a negative feedback loop.

Explanation:hormonal stimuli refer to the release of a hormone in response to another hormone the anterior pituitary in turn releases hormones that regulate hormone production by other endocrine glands.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

cell division is not regulated in tumor cells.
