VC1.H1.5 Dorsal Root Ganglion

Dorsal Root Ganglion:

    Dorsal root ganglion
  • The dorsal root ganglion contains the cell bodies of pseudounipolar neurons
  • These are sensory neurons
  • They represent the afferent branch of the spinal nerve arc
  • In the micrograph identify the large rounded cell bodies of the sensory neurons
  • Like all neurons, they are characterised by the presence of a large euchromatic nucleus with a prominent nucleolus
  • What do these features of a cell indicate? How does this apply to neurons?
    Where might the sensory receptors for these neurons be located?
