The lateral palpebral raphe is a ligamentous band near the eye. Its existence is contentious, and many sources describe it as the continuation of nearby muscles. It is formed from the lateral ends of the orbicularis oculi muscle. It connects the orbicularis oculi muscle, the frontosphenoidal process of the zygomatic bone, and the tarsi of the ...
The lateral angles are attached to the zygomatic bone by the lateral palpebral raphe. The medial angles of the two plates end at the lacrimal lake, and are attached to the frontal process of the maxilla by the medial palpebral ligament). The sulcus subtarsalis is a groove in the inner surface of each eyelid.
The palpebral portion of the muscle is thin and pale; it arises from the bifurcation of the medial palpebral ligament, forms a series of concentric curves, and is inserted into the lateral palpebral raphe at the outer canthus (corner) of the eye. [3] The palpebral portion contains the preseptal and pretarsal muscles.
The medial palpebral ligament (medial canthal tendon) is a ligament of the face. It attaches to the frontal process of the maxilla , the lacrimal groove , and the tarsus of each eyelid . It has a superficial (anterior) and a deep (posterior) layer, with many surrounding attachments.
In anatomy, the orbital septum (palpebral fascia) is a membranous sheet that acts as the anterior (frontal) boundary of the orbit. It extends from the orbital rims to the eyelids . It forms the fibrous portion of the eyelids.
The lateral palpebral arteries are the two large branches of those terminal branches of the lacrimal gland that supply the eyelid, with one lateral palpebral artery supplying one eyelid or the other. They pass medial-ward within the eyelid. They anastomose with medial palpebral arteries to form an arterial circle. [1]
It creates the lateral margin of the lacrimal sac fossa and is continuous with the orbital margin. The medial palpebral ligament is attached to anterior lacrimal crest. It is an important structure to avoid damaging during rhinoplasty .
Sixth nerve palsy, or abducens nerve palsy, is a disorder associated with dysfunction of cranial nerve VI (the abducens nerve), which is responsible for causing contraction of the lateral rectus muscle to abduct (i.e., turn out) the eye. [1]
