A MANUAL OF ANATOMY 



The superior vermis is composed of five lobules, named, in order 

 from before backwards, the lingula, central lobule, culmen monti- 

 culi, clivus monticuli, and folium cacuminis. The lingula is deeply 

 placed, and consists of about four laminae or folia, which lie over the 

 superior medullary velum as it extends between the superior 

 cerebellar peduncles. Its laminae may be continued on either side 

 over the superior cerebellar peduncle, and, when this is so, the 

 prolongation is known as the frenulum lingulae. 



The central lobule is of small size, and lies at the bottom of the 

 incisura semilunaris. It is separated from the lingula by the 

 precentral fissure, and from the culmen monticuli by the post- 

 central fissure. 



The culmen monticuli forms the summit of the superior vermis. 

 It is composed of several laminae, and posteriorly is separated from 

 the clivus by the preclival fissure. 



The clivus monticuli represents the sloping part of the monticulus

cerebelli. It is situated behind the culmen monticuli, and is com- 

 posed of several laminae. Posteriorly it is separated from the 

 folium cacuminis by the postclival fissure. 



The folium cacuminis forms the posterior extremity of the 

 superior vermis, and lies at the posterior notch, where it is placed 

 above the great horizontal fissure. 



The upper surface of each hemisphere is mapped out into lobules, 

 which are continuous with the subdivisions of the superior vermis, 

 with the exception of the lingula. These are called, in order from 

 before backwards, the ala, anterior crescentic lobule, posterior 

 crescentic lobule, and postero-superior lobule. 



The ala is continuous with the central lobule, from which it is
