Orbital Vasculature Part II Flashcards
What are the arteries of the eyebrows
- supratrochlear artery (medial part or brow)
- supraorbital artery (lateral part of brow)
What are the veins that drain the eyebrows
- supratrochlear vein (medial)
- supraorbital vein (lateral)
Both veins drain to either the angular vein or superior ophthalmic vein
Arteries of the palpebrae
- lacrimal artery
- ophthalmic artery and branches
What are the branches of the lacrimal artery associated with the palpebrae
Superior lateral palpebral artery
- peripheral palpebral artery
- marginal palpebral artery
Inferior lateral palpebral artery
- peripheral palpebral artery
- marginal palpebral artery
What are the branches of the superior lateral palpebral artery associated with the palpebrae
Peripheral palpebral artery and marginal palpebral artery
What are the branches of the inferior lateral palpebral artery
Peripheral palpebral artery
Marginal palpebral artery
What are the branches of the ophthalmic artery associated with the palpebrae
- superior medial palpebral artery (and its peripheral and marginal branches)
- inferior medial palpebral artery ( and its peripheral and marginal branches)
Medial and lateral marginal and peripheral palpebral arteries anastomose to form what
The peripheral and marginal palpebral arcades in each palpebral
How do the medial and lateral marginal and peripheral palpebral arteries course
Between orbicularis oculi muscle and tarsal plate
Vertical collateral branches of the medial and lateral marginal and peripheral palpebral arteries
Connect peripheral and marginal arcades and course on either side of the tarsal plate
Branches posterior to the tarsal plate supply what
Palpebral conjunctiva, giving it a reddish pink hue
Veins of palpebral
- superficial temporal vein (lateral part of palpebral)
- angular vein, superior and inferior ophthalmic veins (medial part of palpebrum)
Lymph vessels of the palpebrae
Lymph from the lateral 2/3rds of the upper nad lower palpebrum drains into the preauricular lymph nodes, which lymph from the medial 1/3rd is drained to the submandibular nodes
forniceal conjunctival arterial supply
Branches from peripheral palpebral arcade
forniceal conjunctival venous supply
Small tributaries that drain into anterior ciliary veins
