The refractory period is a short time after an action potential during which the neuron cannot be excited again, ensuring unidirectional impulse propagation without overlap.
فترة الجموح هي فترة قصيرة بعد جهد الفعل حيث لا يمكن للعصبون أن يثار مرة أخرى. تمنع هذه الفترة انتشار جهد الفعل في كلا الاتجاهين، مما يضمن نقلًا أحادي الاتجاه وعدم تداخل النبضات.
| Front | refractory period/hyperpolarisation |
|---|---|
| Back | after action pot, theres a refractory period (axon cant get exited for short period), VGNa+ channels close to prevent Na+ entering axon, refractory period prevents propogation of action pot backwards and forwards (so its unidirectional, doesnt overlap and has distinct impulses) |
