Origin: Occipital artery.
Course: Descend posteriorly to enter the sternocleidomastoid muscle.
Branches: None.
Supplied Structures: Sternocleidomastoid muscle.
Origin
The upper sternocleidomastoid branch of the occipital artery arises from the occipital artery.
Course
There are two sternocleidomastoid branches that arise from the occipital artery, the upper and lower sternocleidomastoid branches.
The upper sternocleidomastoid branch of the occipital artery arises where the occipital artery is crossed by the accessory nerve. The upper sternocleidomastoid branch descends posteriorly, passing the internal jugular vein superficially, to enter the sternocleidomastoid muscle along with the accessory nerve.
Branches
There are no named branches.
Supplied Structures
The sternocleidomastoid branches of the occipital artery help supply the sternocleidomastoid muscle.

Artery
When the artery is occluded blood is forced through the collateral vessels, drastically increasing fluid shear stress and triggering an inflammatory response which drives vessel remodeling.
