Sweet Potato Storage. Unlike potatoes, fresh sweet potatoes generally do not store well, except under ideal conditions, and bruised ones rapidly deteriorate. In a dry, dark, cool (55 degrees F.) place, they can last up to three to four weeks. Plan on using within one week of purchase and do not refrigerate.
During an episode of supraventricular tachycardia (SVT), the heartbeat is not controlled by the SA node (the normal timer of the heart). Patient Access Register
A stimulus is received by the dendrites of a nerve cell. This causes the Na+ channels to open. If the opening is sufficient to drive the interior potential from -70 mV up to -55 mV, the process continues. Having reached the action threshold, more Na+ channels (sometimes called voltage-gated channels) open. The Na+ influx drives the interior of the cell membrane up to about +30 mV.
