When a neuron is not transmitting an impulse, it maintains a resting potential (polarized state) with the outside being more positive than the inside (-70mV), due to ion movement across the membrane.
عندما لا ينقل العصبون نبضة، يكون لديه جهد غشائي يُعرف بالجهد المستقطب، حيث يكون الخارج أكثر إيجابية من الداخل (-70 ملي فولت) بسبب حركة أيونات الصوديوم والبوتاسيوم عبر قنوات الغشاء.
| Front | neurone not transmitting impulse, resting pot meaning, polarisation, how u get resting pot, channels gated |
|---|---|
| Back | when neurone not transmitting impulse, it has resting potential (outside more positively charged than inside), so membrane has p.d accross it at -70mV (polarised), caused by Na+/K+ moving accross membrane via channel proteins (phospho bilayer repels ions), some channels gated (allow specific ions to pass), some always open for Na+/K+ to diffuse |
