Apregnant woman will probably not be able to deliver her baby vaginally if the is not large enough to accommodate

The answer is pelvic outlet. It is because if this is not large enough and it is small, the baby won’t be able to be carried or delivered out from the woman’s vagina as it won’t fit the baby and will likely lead to complications if pushed through.

The answer is absolute refractory period. The absolute refractory period defines the time of latency that happens after a nerve has been fired. Enduring 1-2 minutes throughout this stage the neuron cannot be roused no matter how tough the stimulus is. It is fundamentally renewing itself in order to be capable to fire again. The NA+ stations in the neuron are neutralized throughout the absolute refractory period and are not capable to react to any stimulus. Succeeding the absolute refractory period is the relative refractory period which is longer in extent and is when the neuron is capable to react to a stimulus but desires a stronger than normal stimulus in order to do so.
