pyramidal cells

py·ram·i·dal cells

neurons of the cerebral cortex that, in sections perpendicular to the cortical surface, exhibit a triangular shape with a long apical dendrite directed toward the surface of the cortex; there are also lateral dendrites, and a basal axon that descends to deeper layers.
