Question

Quizplus · Accepted Answer

The shrublike projections are most likely dendrites, which receive signals from other neurons, while the single long projection is most likely the axon, which transmits signals to other neurons. Purkinje fibers are specialized muscle fibers found in the heart and have nothing to do with the brain. Axon terminals are the ends of axons, and presynaptic processes are part of the synaptic transmission process, neither of which fit the descriptions given in the question.
