Action of the poison curare, animation. In the brain presynaptic nerve cells (left) use an electric membrane potential to pass information onto postsynaptic cells (right). This action potential reaches the end of the nerve cell and causes the release of a neurotransmitter acetylcholine (blue and yellow), which works to pass this , potential onto the postsynaptic cell. In this animation curare (red) binds to the acetylcholine receptor (yellow t right) on the surface of the postsynaptic cell. Acetylcholine molecules released from the nerve cell are unable to bind to the receptor. In this way curare blocks the transmission of signals from the brain to the body's muscle groups causing paralysis. | |
