How does presynaptic α2- receptors and prostaglandins E series control sympathetic nervous activity?
Can you give me an example of how this mechanism is used in the body?
Yes, in the gastrointestinal tract, prostaglandins E series are released in response to inflammation or damage. This leads to the activation of α2-adrenergic receptors on enteric nerve endings, resulting in the inhibition of sympathetic nerve activity and enhanced motility and blood flow to the inflamed tissue.
