 ernous sinus. This portion gives off (a) the artkri.e receptaculi branches 

 which pass to the pituitary body, Gasserian ganglion, and to the walls of the 

 cavernous sinus and inferior petrosal sinus, (b) anterior meningeal which 

 passes over the lesser wing of the sphenoid to the dura mater in the anterior 

 fossa, ici ophthalmic — this artery has been described od page 383, (4) The
