Neurotransmitters a chemical messenger that communicates across a synapse Neuromodulators a chemical messenger that communicates with target cells more distant than the synapse by diffusing away from the point of release Neurohormones a chemical messenger that communicates with target cells at a great distance, often by traveling through the circulation Cholinergic releasing or activated by acetylcholine or a related compound Acetylcholinesterase (AChE) an enzy...

What is the action of acetylcholine and where is the site of action? Action Site: Excitatory Neuromuscular junction of some CNS pathways Acetylcholinesterase inhibitors, often used to treat neurobiological disorders: Increase synaptic Transmission Researchers find a compound that when applied to neurons, activates a protein involved in vesicle fusion with a presynaptic membrane. This compound would: Increase synaptic transmission Resting Potential Na- and K- channels are closed K- is concent...
