The levator palpebrae superioris receives motor innervation from the superior division of the oculomotor nerve. [ 1 ] [ 2 ] [ 3 ] The smooth muscle that originates from its undersurface, called the superior tarsal muscle is innervated by postganglionic sympathetic axons from the superior cervical ganglion .
The superior tarsal muscle receives its innervation from the sympathetic nervous system. Postganglionic sympathetic fibers originate in the superior cervical ganglion , and travel via the internal carotid plexus , where small branches communicate with the oculomotor nerve as it passes through the cavernous sinus .

Pain radiating up into the leg, [1] behind the shin, and down into the arch, heel, and toes; Hot and cold sensations in the feet; A feeling as though the feet do not have enough padding; Pain while operating automobiles; Pain along the posterior tibial nerve path; Burning sensation on the bottom of foot that radiates upward reaching the knee
The superior tarsus (tarsus superior; superior tarsal plate), the larger, is of a semilunar form, about 10 mm (0.4 in) in breadth at the center, and gradually narrowing toward its extremities. It is adjoined by the superior tarsal muscle. To the anterior surface of this plate the aponeurosis of the levator palpebrae superioris is attached.
The talus (/ ˈ t eɪ l ə s /; Latin for ankle [1] or ankle bone; [2] pl.: tali), talus bone, astragalus (/ ə ˈ s t r æ ɡ ə l ə s /), or ankle bone is one of the group of foot bones known as the tarsus. The tarsus forms the lower part of the ankle joint. It transmits the entire weight of the body from the lower legs to the foot. [3]
In the human body, the tarsus (pl.: tarsi) is a cluster of seven articulating bones in each foot situated between the lower end of the tibia and the fibula of the lower leg and the metatarsus. It is made up of the midfoot ( cuboid , medial, intermediate, and lateral cuneiform , and navicular ) and hindfoot ( talus and calcaneus ).
The navicular bone in humans is one of the tarsal bones, found in the foot.Its name derives from the human bone's resemblance to a small boat, caused by the strongly concave proximal articular surface.
The muscle also attaches to the superior tarsal plate and into orbital bone. [ 1 ] The ligament allows for a change of the functional origin of the levator palpebrae superioris muscle , enabling the superior tarsus (eyelid) to be elevated superiorly rather than directly toward the muscle's origin on the sphenoid bone.
