Artery: Descending branch of occipital artery |
|
Superficial dissection of the right side of the neck, showing the carotid and subclavian arteries. |
Latin |
ramus descendens arteriae occipitalis |

occipital artery |
The descending branch of occipital artery, the largest branch of the occipital, descends on the back of the neck, and divides into a superficial and deep portion.
- The superficial portion runs beneath the Splenius, giving off branches which pierce that muscle to supply the Trapezius and anastomose with the ascending branch of the transverse cervical.
- The deep portion runs down between the Semispinales capitis and colli, and anastomoses with the vertebral and with the a. profunda cervicalis, a branch of the costocervical trunk.
The anastomosis between these vessels assists in establishing the collateral circulation after ligature of the common carotid or subclavian artery.
