text: The<unk>  (internal<unk><unk> , two in number, superior and inferior, arise from the ophthalmic, opposite the pulley of the Obliquus superior; they leave the orbit to encircle the eyelids near their free margins, forming a superior and an inferior arch, which lie between the Orbicularis oculi and the tarsi.
  The superior<unk>  anastomoses, at the lateral angle of the orbit, with the zygomaticoörbital branch of the temporal artery and with the upper of the two lateral<unk>  branches from the lacrimal artery.
  The inferior<unk>  anastomoses, at the lateral angle of the orbit, with the lower of the two lateral<unk>  branches from the lacrimal and with the transverse facial artery, and, at the<unk>  part of the lid, with a branch from the angular artery.
  From this last anastomoses a branch passes to the nasolacrimal duct, ramifying in its mucous membrane, as far as the inferior meatus of the nasal cavity.
