ABSTRACT
Hippocampus is a component of limbic system associated with learning, memory and emotions, diseases resulting in the deficiencies in the process of above functions which could be a consequence of a change in the morphology induced by some pathology, hence to locate the pathology normal mophometric data is essential. In the present study Hippocampi which were dissected out from 50 adult male cadavers were subjected to morphometric evaluation to obtain the following mean values . Average adult cadaver age and weight of whole brain were 56.5 years, 1035.4gm respectively. The average values of right hippocampus were recorded as follows weight 4.11572 gm, length 6.996 cm, width 1.998,volume
13.978 and surface area11.839 cubic centimetre while left hippocampus mean values were weight
3.96458gms,length 6.995, width 1.998,volume 13.976 and surface area 11.713cc.There was no influence of weight on volume .
Key Words: Hippocampus, Limbic System and Morphometric data.
INTRODUCTION
Illustrative role can be attributed to Hippocampus in the process of learning and memory. Being an integral part of the functionally connoted Limbic part of brain, located in the inferior horn of the lateral ventricle hippocampus holds the most important share in the functioning of the limbic system. Anatomy of neocortical mantle encircling the base of the cerebral hemispheres was called as Le grand lobe limbique by Broca an eminent neuroanatomist to include subcallosal, cingulate and parahippocampal
