pyramidal cell
pyramidal cell
Danh từ
Số nhiều: pyramidal cells
This term is a specialized anatomical descriptor used almost exclusively within neuroscience and histology. It describes a specific morphology where the soma is triangular, facilitating a distinct arrangement of dendritic trees that allow the neuron to integrate a vast amount of synaptic input from various cortical layers.
In a clinical or research context, the term is used to distinguish these excitatory neurons from inhibitory interneurons. Because it refers to a specific biological structure, it is used in a literal, descriptive sense and does not carry metaphorical extensions in standard English.
