What Releases Oxytocin
Pituitary: Hi. ADH (vasopressin) & oxytocin are made in neurons in the hypothalamus and travel down the axons in the pituitary stalk to the posterior pituitary where they are stored until they're released. They're referred to as "posterior pituitary hormones", but they're made in the hypothalamus and only stored and released from the posterior pituitary. ...Read more
Insulin: GnRH is stimulated by an increase in insulin (as can be seen in PCOS). An increase in prolactin causes a decrease in GnRH. GnRH is low in early childhood, then is activated in puberty, and has a pulsatile release for normal reproductive function. What exactly initiates puberty is not completely known with biological and environmental factors playing a role. ...Read more
Complex: It is a neurotransmitter, mostly in the brain and the gi system. It is released when that neuron electrically achieves an action potential, based on its interactions with other neurons. Those interactions are complex. What is more complex is the many different kinds of receptors, which do many different things. ...Read moreSee 1 more doctor answer
Tissue hypoxia: Lack of adequate oxygenation of tissues is the usual signal for EPO release. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex. ...Read more
Can you tell me about hormone physiology: what's the difference between follicle-stimulating hormone & luteinizing hormone?
What hormone inhibits the secretion of adh (vasopressin)? And what situations override the release of this inhibiting hormone?
ADH (vasopressin) secretion: ADH (vasopressin) is mostly controlled by plasma osmolality and plasma volume. Diabetes insipidus occurs when ADH (vasopressin) is not secreted (head trauma, pituitary tumor) or when the kidney does not respond to it (nephrogenic di). Ethanol inhibits adh, (vasopressin) as does atrial naturetic protein, but these are lesser influences than osmolality and volume. ...Read more
Fetal statuss check: A oxytocin challenge test(oct) involves giving a pregnant mother the drug to stimulate at least 3 contractions in a 10 minute interval to check whether the fetal heart rate accelerates(reassuring) or declines. It allows the OB md to check on the fetal status especially when there are concerns about the baby's wellbeing. ...Read more
When the egg matures and releases high estrogen, brain starts releasing LH that trigger ovulation.Clomid (clomiphene) is estr receptr.How come estr surge possibl?
Question?: Each month, fsh is produced that recruits eggs which produce estrogen. The rise in estrogen eventually triggers the lh surge and ovulation. Clomid (clomiphene) is a weak "anti-estrogen" and tricks the brain into over-stimulating the ovaries and increases changes of ovulation, to put it simply. Your question is worded poorly, but i hope this is a good answer for you. ...Read more
Pitocin (oxytocin): Pitocin (oxytocin) is what your own body makes to help you squeeze out a baby. It helps increase the effectiveness of the contractions. Drs can add a supplement to assist labor & at proper doses it speeds the process.Babies can grow well during pregnancy with a cord/placenta that in not healthy enough to endure the stress of labor(leading to a distress pattern) nurses can stop added pit but not what u make. ...Read more
No: They are different hormones with completely different effects. ...Read more
Benzodiazepines: Benzodiazepines do not directly reduce norepinephrine release, but they do enhance the inhibitory gaba-a receptor function in the brain so that nerve cells downstream will be less active -- including norepinephrine-firing ones. The end effect is sedation, emotional calming, decreased muscle tone and coordination, decreased memory function, and a host of other changes. ...Read moreSee 1 more doctor answer
Nomenclature: Hi. Scientific research has a long and storied history full of nomenclature inconsistencies. Those terms are interchangeable. ...Read more
Good question: Gnrh would seem by its name to help release gonadotropin. And if used in a certain fashion it could cause the release of gonadotropins (lh, fsh). However when given in a shot and having a sustained effect on the pituitary, it actually suppresses the release of lh and fsh. And this aspect of the medication can be used to help in many situations. ...Read more
See below: Epinephrine (also known as adrenaline or adrenalin) is a hormone and a neurotransmitter. Epinephrine has many functions in the body, regulating heart rate, blood vessel and air passage diameters, and metabolic shifts; Epinephrine release is a crucial component of the fight-or-flight response of the sympathetic nervous system. ...Read more
