Levator palpebrae superioris nuclear palsy in a child …
The levator palpebrae superioris is a somatic extraocular muscle that elevates the upper eyelid through innervation by the oculomotor nerve.3 Within the nuclear complex of the third nerve, the levator subnucleus is unpaired and supplies both levator muscles.3 Thus, lesions of the levator subnucleus result in bilateral ptosis.3 Causes of oculomotor nuclear lesions include infarction
Levator Palpebrae Superioris: An Anatomical Update
· ABSTRACT The levator palpebrae superioris (LPS) muscle is the main retractor of the upper eyelid, responsible for elevating the upper eyelid and maintaining it in an open position. Sound knowledge of its anatomy and adjacent structures is essential for eyelid surgery. Work from researchers and anatomists over the years continue to enrich our understanding in the anatomy of the LPS. In this
Levator Palpebrae Superioris Medical Definition
Medical definition of levator palpebrae superioris: a thin flat extrinsic muscle of the eye arising from the lesser wing of the sphenoid bone, passing forward and downward over the superior rectus, and inserting into the tarsal plate of the skin of the upper eyelid which it
Roots of the ciliary ganglion
The levator palpebrae superioris, which is supplied by a branch of the oculomotor nerve, also elevates the upper eyelid. Eyelid elevation is therefore under both voluntary and involuntary control. Interruption of either pathway will result in eyelid droop (ptosis).

· The structure of the superior tarsal muscle is unique in that it adjoins and originates from underneath another muscle, the levator palpebrae superioris. The superior tarsal muscle is visible with the naked eye and is about 15 mm wide by 10 mm long.
The Oculomotor Nerve (CN III)
Overview Motor – Innervates the majority of the extraocular muscles (levator palpebrae superioris, superior rectus, inferior rectus, medial rectus and inferior oblique). Parasympathetic – Supplies the sphincter pupillae and the ciliary muscles of the eye. Sympathetic – No direct function, but sympathetic fibres run with the oculomotor nerve to innervate the superior tarsal muscle (helps

Oculomotor nerve palsy can also cause ptosis (due to a lack of innervation to levator palpebrae superioris) as well as miosis due to the loss of parasympathetic fibres responsible for innervating to the sphincter pupillae muscle. Trochlear nerve palsy (CN IV) .
Levator palpebrae superioris
Der Musculus levator palpebrae superioris („Heber des Oberlides“) ist ein Skelettmuskel in der Augenhöhle, der das obere Augenlid nach oben zieht und damit für die Öffnung der Lidspalte verantwortlich ist. Er gehört zu den äußeren Augenmuskeln, entspringt am kleinen Flügel des Keilbeins und setzt in der Haut und in der Bindegewebsplatte (Tarsus) des Oberlides an. Der Muskel wird vom
