Pyramidal cells

Plate 6.87 Cerebral Cortex: Pyramidal Cells

Mouse, Golgi-Cox method, 162 x.

Cell body: Pyramidal in shape.

Dendrites: Each cell possesses several large tapering processes containing cytoplasmic organelles similar to those found in the cell body. Some dendrites possess spine-like side processes called gemmules, which are seen at higher magnification in Plate 88.

Axon: This process arises in this particular cell from the proximal part of the dendrite. It is slender and of uniform diameter, but variable in length depending upon location. The axon of a motor neuron may exceed 1 m in length.
