Is chain of command a least common way that hormones are regulated?
No, the chain of command is not the least common way hormones are regulated. Hormonal regulation often involves complex feedback systems, including negative and positive feedback loops. Additionally, hormones can be regulated through various mechanisms such as neural control, humoral control, and interactions with other hormones, making the chain of command just one of several regulatory pathways.
Are contractions in the uterus a process regulated by negative or positive feedback?
Uterine contractions are one of the few physiologic process regulated by positive feedback.
Positive feedback differs from negative feedback in that?
Most of the mechanisms in our body are regulated by negative feedback inhibition. In this type of process, the end product shuts off or reduces the intensity of the original stimulus. Production of certain hormones when mother is giving birth to a child is regulated by positive feedback inhibition. In this type of process, response leads to an even greater response.
Is blood regulated by negative or positive feedback?
negative feedback via baroreceptors in the carotid artery and aortic arch
Is blood pressure regulated by positive or negative feedback?
Aldosterone is both responsible for absorption of sodium and excretion of potassium. If it is regulated by the level of potassium in blood, then we have negative feedback as high levels of aldosterone causes a decrease in potassium level in blood. If it is regulated by the level of sodium in blood, the story is just the opposite and we have positive feedback. -my own conclusion from several researches-
What feedback continually enhances the output so that the regulated variable continues to be moved in the direction of the initial change?
Positive feedback continually enhances the output by amplifying and reinforcing the initial change to move the regulated variable in the same direction. It is a self-reinforcing loop that can help drive a system towards a new equilibrium state.
Is gonadotropin negative feedback or positive feedback?
Gonadotropin release is primarily regulated by negative feedback mechanisms. In both males and females, sex hormones (like testosterone and estrogen) inhibit the secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus and luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. However, during specific phases of the menstrual cycle, estrogen can induce a positive feedback loop leading to a surge in LH, which triggers ovulation. Overall, the predominant regulatory mechanism for gonadotropin is negative feedback.
What are the hormonal responses and describe them?
The hormonal responses are basically responses or reactions given by the hormones. This response is triggered by either negative or positive feedback mechanism. When the hormone level is too low, the gland (usually endocrine) releases the hormones into the bloodstreams where it travels until it reaches the target organ. When there are too much hormones, the gland is triggered to stop the release of hormones. This mechanism of maintaining the balance without giving excess amount of hormone is known as negative feedback. In a positive feedback, the gland is triggered to release more hormones when excess amount of hormones is present.
How might a person exhibit positive feedback communication?
Positive feedback increases the original stimulus. An example is labor contractions. The initial contraction signals the body to release hormones that increase the frequency and intensity of subsequent contractions.
Is blood pressure negative or positive feedback?
Is the clotting of blood an example of positive or negative feedback?
Does the endocrine system often run on negative feed back?
Endocrine system usually uses the negative feed back mechanism. So suppose when thyroid stimulating hormone is released, then thyroid hormones are released. They reduce the secretion of thyroid stimulating hormone. This is how the secretions of the hormones is regulated. In positive feed back mechanism, the level of both the hormones will raise and will create lot of problems.
Are blood glucose levels regulated by positive feedback?
No, blood glucose concentration is regulated by negative feedback. When blood sugar levels are too high, the alpha particles in the pancreas' islets of Langerhans signal the pancreas to produce more insulin, which regulates the sugar level by stimulating the liver and other body cells to absorb more glucose at convert it into either glycogen or fat. This lowers the blood sugar concentration. If it were positive feedback, high blood sugar levels would encourage the production of more glucose to increase the blood sugar concentration.
