comment Definition of general anesthesia
Thanks a lot for a great answer. But my primary concern was the discrepancy in the definition. If there is a loss of consciousness, can there be a memory of what transpires therein? Are there cases wherein a person can be rendered unconscious but still not amnesic about that state? And second, if I understand correctly, analgesia in the definition mean a loss of afferent nociceptor input and not just a loss of the perception of those inputs?

comment Definition of general anesthesia
I guess the issue is what we mean by perception. If it strictly means stimuli perception, I guess it's not lost when unconscious. But I meant it more in the sensation way, the feeling of pain way. Sorry for the vague seemingly unscientific usage.

comment Definition of general anesthesia
Well, I looked up the definition from Merriam Webster. But I guess what you state could be classified under the reflex autonomic loops, which I don't think are included under unconsciousness. And I think, probably, that the sensation of pain would begin only when he becomes conscious.

comment Pathogenesis of type IV hypersensitivity
@Kendall So, the tissue injury is just the result of a prolonged activation of the immune mechanisms or of pathogen-mediated misdirection of the system? Thanks. Can you also shed light on the questions following "Moreover, a lot of books....."

comment Why does histamine release in Type I hypersensitivity help in case of parasites?
@Kendall So, what you say is, this kind of degranulation injury is there also in case of parasite-removal, but then the condition is not considered hypersensitivity, since the damage is only a collateral of a positive effect. In case of wrongful stimulation, it is called hypersensitivity, since the deleterious effect is unnecessary? According to AMR, the anti parasite effect is due to histamine acting on the parasite and not on the somatic cells. Also, can you add a reference. Thanks anyways.

comment Why does histamine release in Type I hypersensitivity help in case of parasites?
@AMR Can you elaborate on "Find its target". Is not the effect of these mediators on vasculature and musculature the part of their anti-parasite effect?
