Morphological and morphometric study of insular cortex in human cadaveric brains
Journal Title: Indian Journal of Clinical Anatomy and Physiology - Year 2018, Vol 5, Issue 2
Abstract
Introduction and Aim The insular cortex is hidden 5th lobe of brain with variable gross anatomical patterns Insula is situated in operculoinsular compartment of sylvian cisternMaterials and Methods 58 human formalin fixed cerebral hemispheres were studied for the gyri and sulci variations of insular cortex and their lengths were recorded using digital vernier caliper This study was done in department of Anatomy Gandhi medical college BhopalResult The morphological normal and variable pattern discontinuous sulci and joined gyri were observed Out of the 85406 21 variable pattern we observed 44406 103 Bifid 31406 763 Hypoplastic Gyri and 10406 246Trifid The Bifid pattern was most commonly seen in Anterior Short Gyrus18 44 41 The Hypoplastic pattern was most commonly seen in Middle Short Gyri 1831 58 There was presence of Transverse Gyri in 1358 2241 and Accessory gyri in 3958 6551 cerebral hemispheres Transverse gyrus amp Accessory gyrus both were absent in 1958 3276 cerebral hemispheres in insular cortex Total number of gyri in every insula and Mean lengths of gyri were Anterior short2454mm Middle short2504 Posterior short3408mm Anterior long3687mm Posterior long371mm measured The Mean lengths of all insular sulci were Central Insular353mm Superior Periinsular5248mm Anterior Periinsular245mm Inferior Periinsular264mm Posterior Periinsular1281mm measuredConclusion Variation in morphological pattern of gyri are Bifid Trifid and Hypoplastic The Transverse and Accessory gyri were present in anterior lobule but not observed in each insula There was variation in number of gyri because of presence of transverse and accessory gyrus Total number of gyri are more in anterior lobule so it is larger than Posterior lobule The gyri of anterior lobule are shorter than gyri of Posterior lobule Such morphological features and variations are important for surgeriesnbspKeywords Morphology Morphometric Insular cortex gyri and sulci
