Choose the example that demonstrates a positive feedback loop of hormonal control.Multiple ChoicePressure receptors sense the movement of a baby against and through the cervix during labor. They stimulate the hypothalamus to release a hormone that causes uterine contractions. This causes more pressure receptor stimulation, leading to larger releases of the hormone and stronger, more frequent contractions. Hormone release ceases after pressure sensations cease.A gland releases a hormone that causes free blood glucose to be collected and stored after a meal. After a time, the gland detects low free blood glucose and ceases production of the hormone.A hormone is released from the hypothalamus, stimulating the anterior pituitary gland to release another hormone that is involved in metabolism. The flow of that hormone back to the hypothalamus inhibits the production of the first hormone in the pathway, also ceasing the production of the metabolism-influencing hormone.A hormone that increases blood pressure is released. Baroreceptors in the arteries sense the pressure change and stimulate the brainstem to send signals to dilate blood vessels and counter the effect, decreasing blood pressure.
