🚀 The Big Picture: Your brain is like a massive control center, sending messages all over your body. How does it do it? Through neurotransmitters! Imagine neurotransmitters as tiny little messengers that have the super-important job of passing on messages from one neuron to another. It’s like texting your friend, but inside your brain!

Journey of a nerve impulse

  • What happens? A nerve impulse travels down the presynaptic neuron. It's like a train on its tracks, zooming towards its final stop: the presynaptic membrane.
  • Fun fact: This is super quick, like the speed of a text message being sent!

Party at the presynaptic membrane

  • When the nerve impulse reaches the end of its journey, the presynaptic membrane gets "excited" (depolarized).
  • Real-world example: Imagine getting super excited when you see a notification on your phone – that's the membrane getting depolarized!
