296 THE NERVOUS SYSTEM 



the superior peduncles, connect the cerebellum with the corpora quad- 

 rigemina ; a second, the middle peduncles, form the lateral extensions 

 of the pons Varolii ; the third, inferior peduncles, connect with the 

 spinal cord. By severing the connections of the cerebellum the cut 

 ends of these peduncles may be seen. Other parts of the brain can 

 be identified by comparing with the illustrations of the human brain 

 given in the general text. 



If the brain has been carefully removed from the skull, the twelve 

 pairs of cranial nerves can be identified by careful dissection and by 

 comparison with the figures of the human brain.
