yian Artery. 



Further branches of the ophthalmic artery are: 



g) The palpebral, Art. palpebralis interim superior et inferior, 

 which supply the lachrymal sac, caruncle and conjunctiva, and pass 

 into the eyelids ; 



h) The frontal, Art. frontalis, passes around the Maryo mfraorbitalis 

 to the forehead; 



i) The nasal, Art. dorsalis nasi, perforates the M. orbicular is and 

 finally unites with the angular artery, the termination of the facial. 



Other branches of the internal carotid are: 



2. The posterior communicating, Art. communicans posterior, 

 which, passing backwards, anastomoses with the posterior cerebral, and 

 helps to form the circle of AY i 1 1 i s, Circulus arteriosus Willisii. 



3. The c h o r o i d, Art. clioroidca to the Plexus choroideus lateralis. 



4. The anterior cerebral or Art. cohorts callosi, passes for- 

 wards, is connected by means of the anterior communicating 

 artery with the corresponding artery of the other side, and ascends 

 to the Corpus callosum, to supply the hemispheres of the brain. 



5. The middle cerebral or Art. fossae Sylvii divides in the 

 fossa of Sylvius into a number of branches for the anterior and inferior 

 cerebral lobes.
