Dendrites do not have to originate on the cell body.  Invertebrate
neurons are typically unipolar with the cell body stuck off to the
side somewhere.  Still, there is a branching pattern of dendrites that
function just the same as do those in a multipolar neuron.  The only
difference is the location of the soma.

Google on "unipolar neuron" to see pictures.  For example
