artery which passes through the optic foramen into the orbit with the optic 

 nerve. However, this artery sometimes passes with the ophthalmic vein through 

 the anterior lacerated or sphenoidal fissure. In the orbit it gives off the fol- 

 lowing branches, an orbital group and an ocular group. The branches of the 

 orbital group are: 



1. Lachrymal. 2. Supraorbital. 3. Posterior ethmoidal. 



4. Anterior ethmoidal. 5. Internal palpebral. 6. Frontal 



7. Nasal.

The lachrymal is one of the largest branches from the ophthalmic ami 

 comes off close to the optic foramen although it may come off before the artery 

 passes through the optic foramen. Occasionally it is derived from one of the 

 anterior branches of the middle meningeal artery. It passes along the outer 

 wall of the orbit above the External rectus muscle with the Lachrymal nerve. 

 It is distributed to the lachrymal gland and to the eyelids and conjunctiva. 

 Those to the lids are two in number, called the external palpehral running in the
