1. Smoking or caffeine can cause a problem if the sympathetic nerves are sensitive. 2. Empirically proven effects include sympathetic nerve discharge and increased arterial pressure. 3. Chibana's battle has hit a sympathetic nerve with his fellow Okinawans. 4. The effects of such stress can affect the sympathetic nerves controlling arterial blood supply. 5. He also proved the heart had a double innervation through the vagus and sympathetic nerves . 6. This leads to sympathetic nerve activation, resulting in alpha1 vasoconstriction-- > renin secretion through ? 1-receptors. 7. The sacral sympathetic nerves contain a mix of preganglionic and postganglionic sympathetic fibers, but mostly postganglionic. 8. For many responses to sympathetic nerve stimulation, the ATP co-stored with noradrenaline ( see above ) is a purinoceptors. 9. It is a direct vasodilator, relaxing smooth muscles, and it inhibits the release of noradrenaline from sympathetic nerve terminals. 10. These cells secrete high levels of CXCL12 and closely associate with sympathetic nerves that influence cytokine-induced migration of HSCs.
