Anatomy & Physiology
Continuous propagation cannot occur in the myelinated axons because:
To successfully initiate an action potential the resting membrane potential needs to be:
What is the direct effect of repolarization in a nerve cell:
Which of the following describes the absolute refractory period?
What happens during an absolute refractory period?
Cardiac muscle cells can generate action potentials spontaneously without external nervous input. This is due to which of the following specialized cells?
When an action potential reaches the axon terminal, it depolarizes the membrane. As a result:
