Last time we looked at an action potential happening across a neurone cell-surface membrane. The membrane was depolarised and repolarised. However, that depolarisation must be propagated along the whole length of a neurone in the right direction. Today we will look at how an action potential works it's way along in a wave of depolarisation.... Continue Reading →
Action Potential – Nervous Communication Ep 3
In the last article we learnt that neurone cell-surface membranes are polarised at rest (when they are not being stimulated). However, when a stimulus is detected, a nerve impulse must be transmitted along the neurone. Today we will look at the sequence of events that happens during an action potential and how ion channels bring... Continue Reading →
