Lesson 17:  Synapse, Neurotransmitters, and Neuroreceptors

• Understand the relative intracellular and extracellular concentrations of sodium, potassium, calcium, and chloride ions
• Outline and clearly explain the steps that occur to pass a nerve impulse from one neuron to another
• Know the structure of acetylcholine and explain how it is synthesized and hydrolyzed
• Clearly explain the two major mechanisms used to reduce neurotransmitter concentration levels at nerve synapses
• Understand the two (nicotinic and muscarinic) major classes of cholinergic (acetylcholine) receptors and the mechanism of action for each
