Costocervical trunk

The costocervical trunk (ribs and neck strain) is an artery ( artery), which rises slightly to the side of the internal thoracic artery (internal thoracic artery) from the subclavian artery ( subclavian artery). The vessel master supplied with its branches the intervertebral spaces I and II and the deep neck muscles.

Branches

The costocervical trunk is relatively short in humans, and then divides into the deep cervical artery (deep cervical artery) and the artery intercostal suprema (highest intercostal artery) on.

The deep cervical artery draws between the transverse processes of the 7th cervical vertebra (C7) and the first thoracic vertebra (Th1) to the deep neck muscles, which it supplies with oxygen-rich blood.

The artery intercostal suprema pulls downward toward the neck of the first rib and divides there into two more branches at: posterior intercostal artery prima ( first rear intercostal artery) and posterior intercostal artery secunda (second posterior intercostal artery). They supply the corresponding intercostal spaces. Both arteries form within the intercostal spaces anastomoses with the anterior intercostal Rami I et II (anterior intercostal branches I and II), branch off from the internal thoracic artery ( internal mammary artery).
