Question

Quizplus · Accepted Answer

Axons and dendrites do continue to grow throughout life, but only the tiny projections on dendrites called spines increase in size and number. Axon terminals are the end points of axons where they make contact with other neurons or muscle cells. Precursor cells and stem cells are involved in the production of new neurons, but they do not directly contribute to the growth of axons and dendrites already in place.
