Ramus sternocleidomastoideus inferior arteriae occipitalis
Read moreQuick Facts
Origin: Occipital artery.
Course: Descend posteriorly to enter the sternocleidomastoid muscle.
Branches: None.
Supplied Structures: Sternocleidomastoid muscle.
Origin
The lower 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 lower sternocleidomastoid branch arises near the origin of the occipital artery from the posterior aspect of the external carotid artery. The lower sternocleidomastoid branch descends posteriorly, traversing the hypoglossal nerve and internal jugular vein and enters the sternocleidomastoid muscle.
Branches
There are no named branches. The lower sternocleidomastoid branch of the occipital artery forms an anastomosis with the sternocleidomastoid branch of superior thyroid artery.
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.
