INTERNAL CAROTID. 



vertically downwards behind the posterior border of the Sterno-mastoid, to terminate 

 in the Subclavian; it receives the transverse cervical and suprascapular veins, 

 which occasionally form a plexus in front of the artery, and a small vein which 

 crosses the clavicle from the cephalic. The small nerve to the Subclavius also 

 crosses this space about its centre. 



INTERNAL CAROTID ARTERY. 



The Internal Carotid Artery commences at the bifurcation of the common 

 carotid, opposite the upper border of the thyroid cartilage, and ascends perpen- 

 dicularly upwards, in front of the transverse processes of the three upper cervical 

 vertebrae, to the carotid foramen in the petrous portion of the temporal bone.
