of the nucleus caudatus situated in the ventriculus lateralis. 

 Locate the foramen interventriculare (foramen of Monro) . 



Ventriculus tertius, tuber cinerium, infundibulum, and hy- 

 pophysis. 



Corpus mamillare and fornix, showing columna fornicis and 

 taenia fornicis. 



Gyri and sulci: sulcus corporis callosi, gyrus cinguli (gyrus 

 fornicatus), gyrus hippocampi, and fissura hippocampi ; sulcus 

 cinguli (calloso-marginal), gyrus frontialis superior, lobulus para- 

 centralis, praecuneus, sulcus subparietalis, fissura parieto-occipi- 

 talis, cuneus, fissura calcarina, and gyrus lingualis. 



What is the relation of the sulcus centralis to the lobulus 

 paracentralis ? From what does the cuneus derive its name ? 

 What is the relation or the tractus opticus to the thalamus opti- 

 cus ? The fornix to the corpus mamillare ? 



2. Lobi cerebri. — Determine the lobes of the Telencephalon 

 and their component parts as follows : 



a. Lobus frontalis. — Convex surface : gyrus centralis anterior 

 (bounded posteriorly by sulcus centralis or fissure of Rolando), 

 gyrus frontalis superior, sulcus frontalis superior, gyrus frontalis 

 medius, sulcus frontalis inferior, and gyrus frontalis inferior with 

 pars opercularis, pars triangularis, and pars orbitalis. 



Mesial surface : gyrus frontalis superior, lobulus paracen- 

 tralis, and sulcus rostralis. 



Ventral surface: gyri orbitales, sulci orbitales, sulcus olfacto- 

 rius, and gyrus rectus. 



;8. Lobus parietalis. — Convex surface: gyrus centralis poste- 

 rior (bounded anteriorly by sulcus centralis), lobulus parietalis 

 superior, lobulus parietalis inferior, and sulcus interparietalis. 



Mesial surface: praecuneus (bounded posteriorly by fissura 

 parieto-occipitalis) and sulcus subparietalis. 



7. Lobus occipitalis. — Convex surface: gyri occipitales supe- 

 riores, sulci occipitales superiores, gyri and sulci occipitales 

 laterales. 



Mesial surface: Cuneus, fissura calcarina, and gyrus lin- 

 gualis.
