Description[edit | edit source]
Iliocostalis Thoracic is also know as iliocostalis dorsi.It is the thoracic segment of the iliocostal muscle.[1]
Origin[edit | edit source]
It is originated from the superior aspect of the angle of the lower six ribs( 6-12 ribs). It is medial to iliocostalis lumborum's insertion.[2]
Insertion[edit | edit source]
It is inserted at the angles of the upper six ribs(1-6 ribs) and the transverse process of C7 vertebra.[2]
Nerve[edit | edit source]
It is innervated by the lateral branches of the posterior primary divisions (dorsal rami) of the thoracic spinal nerves.[2]
Artery[edit | edit source]
The blood supply is provided by the dorsal rami of the posterior intercostal arteries.[1]
Function[edit | edit source]
The muscle extends and laterally flexes the Thoracic spine.[2]
When acting bilaterally, it participates in the extension of the thoracic spine in synergy with the iliocostalis cervicis, iliocostalis lumborum, longissimus cervicis, spinalis thoracis, semispinalis cervicis, and semispinalis thoracis muscles. When acting unilaterally, it is a lateral flexor of the thoracic spine.[1]
