[Experimental anatomical data on the structure of retrobulbar nervous plexus in man and various laboratory animals]. / Anatomo-éksperimental'nye dannye o stroenii retrobul'barnogo nervnogo spleteniia u cheloveka i nekotorykh laboratornykh zhivotnykh.

Retrobulbar nervous plexuses were studied in man, albino rat, guinea pig and rabbit by means of macro- and micropreparation with elective dyes use, histotopogrammes and in the experiment with sympathetic superior cervical node removal. It was established that models characteristic for mammals were present in this plexus structure. Branches of abducent nerve conducting sympathetic fibres to the eyeball are the part of the plexus in rodents and the rabbit. In all the cases sympathetic fibres to the eyeball pass without contact with ciliary ganglion, apart from guinea pig, in which portion of sympathetic fibres passes through additional ciliary ganglia. Only in man ciliary ganglion has sensory root although sympathetic fibres are not discovered in trigeminal nerve branches.
