Talk about dendrites.

They are non-myelinated expansions of the cell body, differentiated for the reception of the nervous message (afferent). Most often they are short and very ramified. Their number, their length and the mode of spatial distribution of their ramifications vary from one neuron to another. They contain the same cytoplasmic organelles but no neurofilaments or Golgi apparatus. Their surface is irregular and presents lateral protrusions called dendritic spines
