The internal jugular vein ( Vena jugulari%\ (Fig. 160 J) can 

 IK? traced from the border of the 31. favafor $cajj/ai- upwards and 

 forwards to the hinder part of the prootic bone : it then passes 

 forwards under the lateral process of the prootic, in a groove on 

 the anterior surface of the same bone, towards the hinder angle of 

 the orbit, where it receives the veins from the cranial cavity (see 

 vessels of brain, p. 165), and also a branch from the orbit.

 The vessel lies close to the cranium, immediately underneath the
