Which cell type is the pyramidal cell located in the cerebrum?

• A. Pyramidal cell of cerebellum
• B. Purkinje cell of cerebellum
• C. Pyramidal cell of cerebrum
• D. Purkinje cell of cerebrum

Answer: (C)

Pyramidal neurons in the cerebral cortex are the main excitatory output cells of the cerebrum. They have a triangular, pyramid-shaped soma with a prominent apical dendrite that extends toward the surface and several basal dendrites, and their axons project to other cortical areas and subcortical targets. This combination of structure and function is what defines them as the cortical pyramidal cells. In contrast, Purkinje cells are characteristic of the cerebellar cortex and are inhibitory, with a distinctive large, fan-shaped dendritic tree. Since the cerebellum does not contain pyramidal neurons, choosing a pyramidal cell of the cerebellum would be inaccurate. Therefore, the cell type associated with the cerebrum in this question is the pyramidal cell of cerebrum.
