Question

threshold potential for impules​

Answer 1

Answer:

The threshold potential for most excitable cells is about 15 mV less negative than the resting membrane potential. In a nerve, if the membrane potential decreases from -70 mV to -55 mV the cell fires an action potential which propagates along the axon.
