Anatomical terminology

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
    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.
