What is the term used to describe the state of an axon in the later phase of an action potential during which an increase in current is required to produce another action potential? partially inhibited refractory relatively refractory disequilibriated refractory relatively disinhibited refractory

Introduction 

A cell location's membrane potential experiences an action potential when it rapidly rises and falls. Subsequently, this depolarization causes similar depolarization in nearby areas. Excitable cells, which are a group of animal cell types that include neurons, muscle cells, and some plant cells, exhibit action potentials. Additionally excitable cells include some endocrine cells, including some anterior pituitary gland cells and pancreatic beta cells.
