Several factors have been considered risk factors for a poor pain prognosis, including young age, high levels of opioid tolerance, neuropathic pain condition, incident pain, psychological distress, history of … WebbThis absolute refractory period in the frog sartorius at 0 °C lasts about 10 milliseconds after stimulation. Therefore, a second pulse within that time span will not elicit any response. If, however, the pulses are 300 milliseconds apart, the muscle will be relaxing when the second pulse is given, and the tension will appear in waves in phase with the …
WebbThe refractory period in cardiac physiology is related to the ion currents that, in cardiac cells as in nerve cells, flow into and out of the cell freely. The flow of ions translates into a change in the voltage of the inside of the cell relative to the extracellular space. As in nerve cells, this characteristic change in voltage is referred to ... Webb16 feb. 2024 · The refractory period is the length of time after an orgasm when sexual desire and the ability to have sex temporarily cease. In males, the refractory period can last from minutes to days. In females, the refractory period may be brief or not occur at all. The refractory period in males is heavily influenced by hormones.
