They are two in number, superior and inferior, arise from the [[ophthalmic]], opposite the pulley of the [[Obliquus superior]]. ==Course== 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 palpebral'' arch anastomoses, at the lateral angle of the orbit, with the [[zygomaticoörbital branch]] of the [[temporal artery]] and with the upper of the two [[lateral palpebral branches]] from the [[lacrimal artery]]. The ''inferior palpebral'' arch anastomoses, at the lateral angle of the orbit, with the lower of the two lateral palpebral branches from the lacrimal and with the [[transverse facial artery]], and, at the medial 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]]. ==Additional images== <gallery> Image:Gray515.png|Bloodvessels of the eyelids, front view. </gallery> {{Gray's}} {{circulatory-stub}} {{Arteries of head and neck}} [[Category:Arteries]]
