Definition

Projection neurons in the CEREBRAL CORTEX and the HIPPOCAMPUS. Pyramidal cells have a pyramid-shaped soma with the apex and an apical dendrite pointed toward the pial surface and other dendrites and an axon emerging from the base. The axons may have local collaterals but also project outside their cortical region.

Common questions about Pyramidal Cells

What does Pyramidal Cells mean in medicine?
Projection neurons in the CEREBRAL CORTEX and the HIPPOCAMPUS. Pyramidal cells have a pyramid-shaped soma with the apex and an apical dendrite pointed toward the pial surface and other dendrites and an axon emerging from the base. The axons may have local collaterals but also project outside their cortical region. This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Pyramidal Cells known by any other names?
Yes. Pyramidal Cells is also referred to as Cell, Pyramidal, Cells, Pyramidal, Pyramidal Cell, Pyramidal Neurons in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
Where does Pyramidal Cells sit in the medical classification?
Pyramidal Cells falls under the broader medical category "Anatomy" in the MeSH hierarchy (tree numbers: A08.675.790, A11.671.790). Browsing the related concepts on this page takes you to neighbouring topics in the same branch of medicine.
