Synaptic cleft-space between axons and dendrites
B. Lock and Key a. Each receptor accepts a certain shape b. Neurotransmitters will lock themselves into receptors c. In the shape almost fits-sometimes the receptor will let it fit d. Reuptake pump C. Types of Neurotransmitters a. Acetylcholine-skeletal muscle fibers b. Dopamine-learning attention movement and reinforcement c. Nor epinephrine-eating habits and alertness d.
