Document Summary
The restoration of the membrane potential to -70 mv is produced by an opening of channels to k+ The ap is conducted along the axon toward the terminals (the one sending the message), the only neurons that receive information first in line are our sensory neurons. 2. if they don"t bind, (they don"t last long in the synapse) deactivated. Acetylcholine muscle movement, attention, arousal, memory. Novocain = is a local anesthetic, and works by sending messages that don"t allow any neurons to open sodium channels (no feeling). Neurotransmitters are what make everything work, without it you are dead. Any disruption will be seen in a disorder.
