Some cells have multiple dendrites and/or axons. What advantages does this have for the nervous tissue?

It receives information from several cells.

Explanation:

The main advantage of cells having multiple dendrites and/or axons is that it receives information from several cells as compared to those cells which have one dendrite and receive information from only one cell. If neurons have hundreds or thousands of dendrites, so these dendrites allow the cell to receive information from thousands of other cells. So we can say that dendrites number plays a key role in nervous tissue.
