Synaptic transmission, animation

Videonummer 11935708
Synaptic transmission with acetylcholine, animation. In the brain, nerve cells use an electric membrane potential to pass information onto postsynaptic cells. This action potential reaches the end of the nerve cell and causes the release of a neurotransmitter which works to pass this potential onto the postsynaptic cell. In this animation the neurotransmitter acetylcholine (yellow and purple) binds to a membrane receptor (yellow) on the surface of the postsynaptic cell. The receptor then acts as a channel, opening to allow sodium ions (red) to cross the membrane. The movement of these ions changes the action potential of the postsynaptic cell. Once this action has been performed acetylcholine is rapidly broken down to by the enzyme acetylcholinesterase (red).
