Inhibition of pain transmission
WebbThe perception of pain caused by inflammation serves as a warning sign to avoid further injury. The generation and transmission of pain impulses involves various pathways and receptors. Cardamonin isolated from Boesenbergia rotunda (L.) Mansf. has been reported to exert antinociceptive effects in thermal and mechanical pain models; however, the … Webb11 maj 2024 · Other receptor systems have been identified in the dorsal horn, many with receptors that are present on primary nociceptor terminals, that may also have inhibitory roles in pain transmission. …
