Central nervous system
... As in other types of cells, a neuron’s cell body (or soma) contains the nucleus and ribosomes and thus has the genetic information and machinery necessary for protein synthesis. The dendrites are a series of highly branched outgrowths of the cell body. They and the cell body receive most of the i ...
