[Shape and size of the corpus callosum and the septum pellucidum].

The mean are of the Corpus callosum at median sagittal sections of 100 brains of adults comes to 622 (330 to 900) mm2. The Corpus callosum has a mean length of 73.7 (62 to 86) mm and a mean height of 23.06 (16 to 31) mm. The Genu corporis callosi has a mean thickness of 11.68 mm and the Splenium of 11.98 mm. The Truncus has a greatest thickness of 6.68 and a smallest thickness of 4.49 mm on an average. In the rostral third the Truncus has a mean thickness of 6.11 mm, the middle of the Corpus callosum of 5.66 mm and the support of the Fornix 5.75 mm. The Corpus fornicis supports in the mean of 48.45 mm behind the rostal end of the Genu corporis of the underneath area of the Corpus callosum. This is observed in 77% in the third, in 19% in the fourth and in 4% in the second quarter of the Corpus callosum. The Septum pellucidum has a mean surface area of 292 (100 to 700) mm2 at median sagittal sections.
