in front and behind are found the anterior and posterior con- 

 dylar foramina, the former of which transmits the hypoglossal 

 nerve. The basilar process, in front of the foramen magnum, 

 is a stout bar of bone articulating with the body of the 

 sphenoid. 



The occipital bone articulates with the two parietals above, 

 with the sphenoid in front and below, externally with the 

 temporals, and below with the atlas.

FIG. 42. THE RIGHT TEMPORAL BONE. 



The Temporal bone consists of a plate of bone, having on its 

 lower border three processes. The inner part of the temporal

 is seen just behind the root of the zygomatic process at the 

 lower border of the squamous part (flat plate). The zygomatic 

 process is a bar of bone projecting horizontally forwards. Just 

 in front of the root is the surface for articulation with the
