Historical Examples. 1  There was room in it for a girl-partner at the oar, but no accommodation for passengers. 2  Every man and spar and oar on the vessel seemed burning in its light. 3  An oar has been made since I came in, wanting the shaped handle. 4  Greer went back to the stern, picked up an oar and began to scull.
1 Somatostatin inhibits growth hormone release in response to GHRH and to other stimulatory factors such as low blood glucose concentration. 2  Ghrelin is a peptide hormone secreted from the stomach. 3  Ghrelin binds to receptors on somatotrophs and potently stimulates secretion of growth hormone.
Then the pituitary gland adjusts its release of thyrotropin, the hormone that stimulates the thyroid gland to produce thyroid hormones. Another example of this process is parathyroid hormone, which increases the level of calcium in the blood. When the blood calcium level rises, the parathyroid glands sense the change and reduce their secretion of parathyroid hormone. This turnoff process is called a negative feedback system.
