ABSTRACT
INTRODUCTION:In Mongolia, The anatomists researched morphometric measurements and blood supply ofheart in adult’s liver pancreas, spleen, Ren and spinal cord and etc... The study of morphometricmeasurements of the choroid plexus is not being taught in Mongolia.GOAL:To determine the structure of the choroid plexus of adult brain ventricle.MATERIALS AND METHODS:This study obtained choroid plexus size in 84 dead bodies, which is between the adult and childrenfrom cadavers. To determine the choroid plexus morphometric measurements, the total 336specimens were evaluated. The standards deviation of choroid plexus length and thickness werecomputed in different ages.RESULT:In present study, the maximum length and thickness were determined in ages from 22-60. In presentstudy, the minimum length and thickness were determined in ages 0-10day. In adult, the meanchoroid plexus length was 8.61±0.15 cm of the lateral ventricles and 4.47±0.02 cm of the fourthventricles and 0.56±0.140 cm of the third ventricle and the choroid plexus thickness was 0.5±0.03cm of the lateral ventricles and 0.29±0.01 cm of the fourth ventricles and 0.28±0.01 cm of the thirdventricle.CONCLUSIONS:In adult, the mean choroid plexus length was 8.61±0.15 cm of the lateral ventricles and 4.47±0.02cm of the fourth ventricles and 0.56±0.140 cm of the third ventricle and the choroid plexus thicknesswas 0.5±0.03 cm of the lateral ventricles and 0.29±0.01 cm of the fourth ventricles and 0.28±0.01cm of the third ventricle.The choroid plexus weight was 0.51±0.01 gm in the lateral ventricles and 0.42±0.014 gm in thefourth ventricle.
