Basal view of the brain (Latin)

The inferior surface of the cerebrum is divided by the sulcus lateralis into anterior and posterior parts. In the anterior part, the gyri orbitales (anterior, posterior, medialis and lateralis) and the gyrus rectus can be identified. The gyri orbitales are separated by the sulci orbitales which together form an H shaped groove between the four gyri. The posterior part is marked by two primary anteroposteriorly oriented sulci: the sulcus collateralis and sulcus occipitotemporalis. These two sulci delineate the gyri occipitotemporales (a.k.a. gyrus fusiformis), which are divided by the sulcus sagittalis gyri fusiformis into a gyrus occipitotemporalis medialis and lateralis. The gyrus occipitotemporalis lateralis is continuous with the gyrus temporalis interior around the inferolateral margin. The posterior part of the sulcus collateralis runs parallel to the sulcus calcarinus, and together they delineate the gyrus lingualis. Besides the cortical structures, in this view the glandula pituitaria, corpora mamillaria and corpora geniculata can be appreciated. Lastly, a cross section of the truncus encephali on the level of the mesencephalon reveals its internal structure.
