-Besides their characteristic shape and often large size, most of the cells with very long axons are pyramidals.

-Therefore the cells that run long bundles of parallel (axons are also pyramidals).

-and the cells with many nodes of Ranvier are pyramidals.

-and the cells that intercconect the cerebral hemispheres are pyramidals.

-The cells that recurrently, excitatorily connect are pyramidals.

-Therefore the cells that regeneratively refire for very long total periods are pyramidals.

-The cells that use most energy are pyramidals.
