Neurotransmission ap psych

Dendrites

The branching fibers extending out from the cell body that recieve information from other neurons are called...

Myelin

...wraps many axons, insulating them and speeding their impulses

Reuptake

After neurotransmitters are released into the synapse, many are reabsorbed through a process called...

sensory neurons, interneurons, motor neurons
