therunner Posted November 5 Report Share Posted November 5 I just read somewhere (i think mens health) that the cells in your body that get "excited" when you yawn are the same ones that when you get an erection. I am going to research this and will post the article laterz. Quote Link to comment Share on other sites More sharing options...
therunner Posted November 5 Report Share Posted November 5 This isn't the one I saw but it'll work. Repeated episodes of yawning and penile erection can be induced in rats and other experimental animals by the systemic administration of low doses of dopamine (DA) agonists, such as apomorphine, by the central administration of adrenocorticotropin (ACTH), alpha-melanocyte-stimulating hormone (a-MSH) and related peptides, and by the intracerebroventricular (i.cv.) injection of oxytocin. While the importance of penile erection in reproduction does not need to be further stressed, it is pertinent to recall that yawning, alone or associated with stretching, is considered to be an ancestral vestige surviving throughout evolution, that subserves the purpose of arousal. In particular, the role of yawning could be that of increasing attention when sleep is imminent due to fatigue or boredom but cannot be engaged in, as in face of a danger or social circumstances.
