Costocervical Trunk

Friday, November 20, 2015

The costocervical trunk is a paired, oxygen-rich blood vessel located in the shoulder, one in the left side, the other in the right side. It arises from the upper surface of the subclavian artery and has a short course, dividing into two important branches: the deep cervical artery and the highest intercostal artery. Function: the costocervical trunk supplies the neck and the intercostal rib muscles.
