Etymology: Gk, pyramis + L, cella, storeroom
a neuron with a pyramid-shaped cell body in the gray matter of the cerebral cortex.

pyramidal cell

A large, common neuron found in the cerebral cortex. Pyramidal cells are flask-shaped or triangular, and, in the parts of the cortex with six layers, they occupy the fifth layer. Pyramidal cell dendrites project up into the most superficial layer of the cortex, while pyramidal cell axons run in the opposite direction, i.e., downward and out of the cortex.
