Introduction
Arteries: are vessels that carry blood away
from the heart.
The carotid arteries are blood vessels that
supply blood to the head, neck and brain.
One carotid artery is position on each side
of the neck.
The right common carotid artery
branches from the brachiocephalic
artery and extends up the right side
of the neck
The left common carotid artery
branches from the aorta and extends
up the left side of the neck.
The common carotid artery is found
as duple, with one on each side of
the anterior neck. Each common
carotid artery is divided into an
external and internal carotid artery.
These arteries transfer blood to the
structures inside and outside the
skull.
The external carotid artery brings blood to
structures outside the skull.
internal carotid artery - Supplies oxygenated
blood to the brain and eyes.
We are going to focusing at the internal
carotid artery especially the ophthalmic
artery (OA)
ophthalmic artery (OA)
Structure
The OA emerges from the internal
carotid .
it’s enters the orbit within the dural
sheath of the optic nerve -passes
through the optic canal (below and
lateral to the nerve)
. Branches of the OA supply all the
structures in the orbit as well as
some structures in the nose and face
Central retinal artery
The central retinal artery is the first, and one of the
smaller branches of the OA and runs in the dura
mater inferior to the optic nerve.
the central retinal artery turns superiorly and
runs along the optic nerve continuing along
the center of the optic nerve entering the eye to
supply the inner retinal layers.
These blood vessels can be examined
during a dilated eye exam.
