All of the following features are seen in neurons from dorsal root ganglia, EXCEPT:

All of the following features are seen in neurons from dorsal root ganglia, EXCEPT:

A. They have centrally located nuclei
B. They are derived from neural crest cells
C. They are multipolar
D. They contain lipofuscin granules

Answer is C. They are multipolar
  •  They have centrally located nuclei as in the picture

  • The dorsal root ganglia develops in the embryo from neural crest cells.
  •  These neurons are of the pseudo-unipolar type, meaning they have an axon with two branches that act as a single axon, often referred to as a distal process and a proximal process.

  • Age-related accumulation of lipofuscin pigment in dorsal root ganglion has been noted and studied.
