Dissection of left orbit from an anterior approach
Muscle fibers near medial angle of eyelids
Note that no fibers attach to the anterior surface of the medial palpebral ligament.
1 . Infratrochlear nerve
2 . Muscle fibers which joined frontalis muscle
3 . Periosteum covering nasal bone
4 . Area of origin of superior part of orbicularis oculi muscle
5 . Area of origin of inferior part of orbicularis oculi muscle
6 . Lacrimal part orbicularis oculi muscle
7 . Medial palpebral ligament
8 . Angular head of levator labii superioris muscle (cut across)
9 . Frontal nerve
10 . Corrugator supercilii muscle
11 . Supratrochlear nerve
12 . Orbital septum (note its downward extension deep to the orbicularis muscle toward an attachment on the posterior lacrimal crest)
