% 562. Table of the Foramina and Canals of the Skull, the Bones 

 enclosing them, and the Principal Structxires to which they 

 give Passage. 



The foramina are enumerated, commencing at the caudal end of the skull. Fig. 56, 62. 

 All are lateral or paired except the foramen magnum, which is mesal.
