Taxonomic definition
Taxonomic definition A triangular part of inferior frontal gyrus is a segment of inferior frontal gyrus [segmentum gyri frontalis inferioris ] which lies between the anterior horizontal ramus [ramus anterior sulci lateralis hemispherii cerebri ] and the ascending ramus [ramus ascendens sulci lateralis hemispherii cerebri ] of the lateral sulcus [sulcus lateralis hemispherii cerebri ].
Notes
For subdivision of Broca’s area, see Amunts K, Schleicher A, Bürgel U, et al. (1999 Broca’s region revisited: Cytoarchitecture and intersubject variability. J Comp Neurol 412:319-341). The Sulcus diagonalis (of Eberstaller) is a variable branch of the Sulcus lateralis, dividing the Pars opercularis into two parts. The Sulcus radiatus (of Eberstaller) may indent the Pars triangularis from above.
