Actions Of Oxytocin
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
Negative emotions: Strongly impact our biochemistry in general. They can eventually burn out our adrenal glands. For a lab analysis of neurotransmitters via urine your doc can use neuroscience lab, who specialize in this, along with supplemental formulas to balance things naurally. Peace and good health. ...Read more
Whether heomopathic treatment set right the imbalance of neurochemicals of serotonin and dopamine depression?
No studies: There are no studies that i know of which document serotonin or Dopamine levels during homeopathic treatment. The 2 paradigms of health and illness are very different. Other issue is that no one has proven that neurochemical imbalance directly causes depression, either. It would be an interesting study, but you'd need many well trained homeopaths, & patients willing to have lp's with treatment. ...Read more
Motor cortex: ALL motor activity - not just smiling - is mediated by the motor cortex. The primary motor cortex is Brodmann area 4 in the precentral gyrus. There are 2 kinds of smile: voluntary (cortically mediated) & emotional (mediated by the thalamus). The brain is way, way, WAY more complex than just "action of smiling" vs "(not emotions)." That's a massive oversimplification. ...Read more
Too ,long to answer: Here please discuss with yoru obgyn as i discuss with any of my pts in coral springs and boca raton who may need these medications during their pregnancy and or labor, the idea is to prevent premature labor rather than have to treat it and oxytocin is very safe if used and monitored , I use it frequently for induction and augmenation of labor and it has prevented many csections. ...Read more
What is the neurochemical basis of the feeling of excitement? Which neurotransmitters/hormones are involved?
The short answer: There is not enough room to answer this. Excitement is complicated. Epinephrine, norepinephrine, dopamine, serotonin, glutamate, and GABA play a role in this. Here is a link to a play about the transmitters: http://www.utexas.edu/research/asrec/demoasrec.html ...Read moreSee 1 more doctor answer
Tyrosine: Some feel that stress depletes catecholamine neurotransmitters such as norepinephrine in the brain.Tyrosine is a precursor for the synthesis of catecholamines, norepinephrine, epinephrine, and dopamine. Mental well-being is much more complex than any one neurotransmitter, but supplemental tyrosine may increase ne levels in the brain. Nausea, headache, fatigue, heartburn & arthralgias may come too. ...Read more
I was wondering what are the differences of levophed, (norepinephrine) dopamine and dobutamine in terms of their action?
You Asked for It----: Dobutamine- direct b1 receptor stimulant or agonist in the sympathetic nervous system. Levophed- vasoconstrictor peripherally (alpha adrenergic effects) and beta adrenergic stimulant at the level of the heart and coronary vessels dopamine- dual b1 and Alpha adrenergic effects. Useful in hypovolemic shock because of conservancy of renal blood flow. Also, works centrally in other complex ways. ...Read more
Depends on cervix: Before induction your current cervical exam is used as a determinant for which mode of induction. Cervidil is most likely used when the cervix is less soft, dilated, and effaced (thinned out), and more posterior, as it increases prostaglandins release to stimulate dilation, thinning and softening. Those who are already dilated and effaced benefit more from pitocin (oxytocin). ...Read more
Catecholamines: Behavior is much more complex than neurotransmitter levels alone. But norepinephrine (ne) acts mainly in an area of your brainstem called the locus coeruleus. When released, ne triggers the stress response. Ne is also involved in pain, cognition, mood, emotions, movement and blood pressure. Dopamine is involved in regulating mood, pleasure, delusions, psychosis and drug abuse -- and more. ...Read more
Using knowledge of the dopaminergic neurone, how might one increase or decrease the release of dopamine?
Natural High : There are many ways once can try to increase brain Dopamine levels. But what ever you do, do not do it with drugs. The high is short and "fun"; the fall is miserable and and long. Some supplements can help, but discuss with your doctor before flushing your dollars down the drain. If natural measures fail, there are effective prescription medications which can help with your Dopamine concern. ...Read more
Acog released study re some adverse outcomes of use of pitocin (oxytocin) in labour augmentation. How worrisome is this for those of us who had pitocin (oxytocin) used?
Pitocin (oxytocin) has been : Used for years and continues to be used if it is used properly it is very safe I use it on almost all of my inductions and to augment labor without inducing and augmenting my patients many could have ended up with problems, some doctors abuse and do not use Pitocin (oxytocin) properly ( not too many) in those cases it can cause problems, Pitocin (oxytocin) has saved many of my pts from c-section have done 5000+delivery. ...Read more
