cerebelli and the dura mater of the middle fossa from this ganglion. The three 

 great branches of the fifth nerve, viz., the ophthalmic, the superior maxillary, 

 and the inferior maxillary arise from this ganglion. 



Besides the Gasserian ganglion the fifth nerve has four other ganglia. 

 (1) The Lenticular, ciliary, or ophthalmic ganglion, (Plate CCXIV) is about the 

 size of a pin's head and is reddish gray in color. It is situated between the optic 

 nerve and the External rectus muscle. The ophthalmic artery is generally on 

 its inner side. This ganglion has three roots, (a) the sensory root which

comes from the nasal branch of the ophthalmic and joins the upper angle of the 

 ganglion. This is the long root, (b) The motor root which conies from a 

 branch of the third nerve that passes to the Inferior oblique muscle. This is 

 the short mot and joins the inferior angle of the ganglion, (c) The sw,n-\- 

 thetic root which coin* s from the cavernous plexus of the sympathetic. It 



usually blends with the long root. This ganglion gives off five or ten short 

 ciliary nerves from the anterior superior and the anterior inferior angles. These 

 nerves pass with the ciliary arteries forward, one set above the optic nerve and
