|
Major artery on each side of head and neck. Supplies oxygenated blood to the brain and eyes. |
Internal carotid artery |
Arises from the common carotid arteries. |
|
|
What are the arterial branches of the C6 ophthalmic segment? |
The ophthalmic artery The superior hypophyseal artery |
O.... artery. S.... H.... artery. |
|
|
Structure: Arises from the cerebral part of the internal carotid artery, through the optic canal, alongside the optic nerve to enter orbit. Ends by dividing into 2 terminal branches, supertrochlear and dorsal nasal arteries. |
Ophthalmic artery |
It branches off the C6 segment. |
|
|
Function: Provide arterial supply to orbital structures (eye, optic nerve, extraocular muscles and eyelids) and adjacent structures (nose, forehead) |
Ophthalmic artery |
Branches off segment C6. |
|
|
What branches from the ophthalmic artery? |
Central retinal artery Lacrimal, short and long ciliary, supra-orbital, anterior ethmoidal, medial palpebral arteries. Muscular and recurrent meningeal branches. |
All the things. Too many to hint... Fine. Central retinal artery is one. Good luck! |
|
|
Structure: Arises from the ophthalmic artery Travels along the superior border of the lateral rectus muscle towards the lacrimal gland. Accompanied by the lacrimal nerve and lacrimal vein. |
Lacrimal artery |
If that last sentence on the front doesn’t give it away, I really don’t know what will. |
|
|
Function: Provides arterial supply to lacrimal gland, the eyelid and the conjunctiva. |
Lacrimal artery |
L... |
|
|
Termination: Along it’s path, it gives off lateral palpebral arteries and an anastomotic branch with the middle meningeal arteries. |
Lacrimal artery |

|
|
Structure: Arises from the ophthalmic artery Travels with the supraorbital nerve along the superomedial aspect of orbit. Exits the orbit via the supraorbital notch. Then travels superiorly along the forehead. |
Supraorbital artery |
Supra! |
|
|
Function: Provide arterial supply to the superior rectus, lavatory palpebral superioris muscle, upper lid and skin of forehead. |
Supraorbital artery |
Su... |
|
|
Structure: Arises from the ophthalmic artery Travels through the anterior/posterior ethmoidal foramen (along the medial wall of orbit) Enters the orbit via the anterior cranial fossa. |
Ethmoidal arteries |
Posterior and anterior ... |
|
|
Function: Provide arterial supply to the dura mater, posterior and anterior ethmoidal air cells, frontal sinus, nasal septum and lateral nasal wall. |
Ethmoidal arteries |
Anterior and posterior e.... |

On its path, it gives off lateral palpebral arteries and an anastomotic branch with the middle meningeal arteries. |

|
What is the structure of the central retinal artery? |
Arises from ophthalmic artery. Travels with the dural sheath of the optic tract, inferior to the optic nerve. Close to the eye, the central retinal artery pierces the optic nerve and gives branches along the internal of the retina. |
Beneath the cable, then internal branches. |
|
|
Which artery provides arterial supply to the optic nerve and the retina layer? |
Central retinal artery. |
Central |
|
|
What are the terminal branches of the central retinal artery known as? |
The temporal and nasal branches. |
Temple and nose. |
|
|
What are the three groups of ciliary arteries? |
Long posterior ciliary artery Short posterior ciliary artery Anterior ciliary artery. |
Long and short at the back, and one at the front. |
|
|
What is the structure of the long posterior ciliary artery? |
Arises from ophthalmic artery, posterior to the eye. Close to the optic nerve the arteries pierce the sclera and travel anteriorly towards the iris and the ciliary processes. |
Back of eye. Keeps close to main nerve. Pierces the white, goes towards the pretty bit then the silly processes. |
|
|
What is the function of the long posterior ciliary artery? |
Provides arterial supply to the iris. At the ciliary processes it bifurcates and forms a series of anastomoses which form: - Major arterial circle of the iris - Minor circle of the iris proximal to the pupil. |
Iris. Two parts. |
|
|
Where does the long posterior ciliary artery terminate? |
Along its path it gives off branches to the sclera. |
The white part. |
|
|
What is the structure of the short posterior ciliary arteries? |
Arises from ophthalmic artery. Travels anteriorly from the ophthalmic artery to the back of the eyeball. There, they pierce the sclera. |
Supplies the back of the house. |
|
|
What is the function of the short posterior ciliary arteries? |
Supply the sclera, ciliary processes and optic disc. |
White, sillies, disc. |
|
|
As it terminates, the short posterior ciliary arteries extends arterial branches into...? |
The choroid layer. |
Tigration is seen because of the... |
|
|
What is the structure of the anterior ciliary arteries? |
Arises from muscular branches of the ophthalmic artery. Travels anteriorly within the orbit along the rectus muscles. Two with the RS, RI and RM and one with the RL. Pierces the sclera at the end of the muscles. |
Muscles and white of eye |
|
|
What is the function of the anterior ciliary arteries? |
Provide an arterial supply to the rectus muscles, the sclera, the conjunctiva and iris. |
Muscles, white, conj and pretty part of eye. |
