Rhesus monkey, 10% formalin, H. & E., 612 x.
Ganglion cell body: This is ovoid or spherical. Note the variation in size and intensity of staining. The nucleus is central.
Satellite cells: Concentrically arranged around the ganglion cells.
Capillary: With enclothelial cell nucleus. Located in the connective tissue stroma between ganglion cells. Absence of blood cells from the capillary lumen is due to vascular perfusion fixation.
Axons: Processes of ganglion cells. Intricate coiling and winding denote its proximity to the cell of origin.
Nodes of Ranvier: Site of termination of myelin sheath segments.
Schwann cell nucleus: Flat to oval in shape. Close proximity to myelinated fibers. Schwann cells elaborate myelin sheaths.
T-bifurcation: Ganglion cell axon bifurcates to form peripheral and central processes; hence, dorsal root ganglion cells are termed pseudounipolar.
