What hormone prevents uterus from initiating labor before the designated delivery time?

The hormone levels are one factor. Estrogen increases contractility of the uterus while progesterone inhibits it. Throughout pregnancy, progesterone levels are high, but just before labor, they fall relative to estrogen levels and contractions start. Another hormone called oxytocin also induces labor. The number of oxytocin receptors increases as pregnancy progresses, and hormone levels rise at labor causing the uterus to contract and begin labor. The uterus also has stretch receptors and will not start contracting unless stretched to a certain degree.

What hormone would increase in the blood during dehydration?
Antidiuretic Hormone (ADH). • ADH helps to avoid dehydration or water overload - prevents urine formation
What is an antidiuretic hormone test?
Antidiuretic hormone (ADH) test, also called the Vasopressin test, is a test for the antidiuretic hormone, which is released from the pituitary gland and acts on the kidneys to increase their reabsorption of water into the blood.
What hormone produced by the pancreas prevents hypoglycemia?
Glucagon. This hormone produced in the pancreatic islets works to raise blood glucose levels, preventing hypoglycemia. Insulin does the opposite.
Does up-regulation involve the loss of receptors and prevents the target cells from overreacting to persistently high hormone levels?
I think is down-regulation because a decrease in receptors will occur so less hormone can bind the cell.
Which hormone released by the heart prevents aldosterone release in order to lower blood pressure?
ANP
What hormones prevents excessive water loss by promoting water reabsorption in the collecting duct?
antidiuretic hormone
How the level of a hormone which prevents menstruation remains high during pregnancy even after the corpus luteum has broken down?
Progesterone is the hormone that prevents menstruation and maintain pregnancy. It is initially produced by the corpus luteum. After the corpus luteum has broken down, the placenta takes over the production of progesterone from the 8th week of pregnancy until birth. Therefore, it is the placenta which keeps the level of the hormone (progesterone) high throughout pregnancy.
Why does male patient have contraindication to initiating sprionolactone?
Gynecomastia I a common side effect. Gynecomastia is overdevelopment of the male breast. In response to too much estrogen (a female hormone) or too little testosterone (a male hormone), the glandular tissue of the breast swells and forms a breast bud (enlarged breast).
What gland is responsible for initiating menstrual cycle?
Oestrogen & Progesterone are produced by the Ovaries. Follicle Stimulating Hormone (FSH) & Lutenizing Hormone (LH) are produced by the pituitary gland at the base of the brain. FSH and LH control and stimulate the unripe eggs inthe ovaries to ripen and be released. Oestrogen & progesterone stimulate the formation of the endometrium lining in the womb, and by reducing in levels ultimatly casue the breakdown of the lining, and the ensuing period know as menstruation in human females
Does tubal ligation affect your hormone levels?
No. The tubal ligation prevents the sperm and the egg from meeting. Ovulation still takes place and that is triggered by hormones.
