Description[edit | edit source]
Spinalis Thoracis belongs to the medial column of the erector spinae (Sacrospinalis) group of muscles.
It is the most prominent and well-organised portion of the spinalis muscle with spinalis capitis and spinalis cervicis superiorly.[1] With its muscle fibres running superiorly.
Origin[edit | edit source]
Spinous processes of T11-L2.[1][2]
Insertion[edit | edit source]
Spinous processes of T2-T8.[2]
Nerve[edit | edit source]
Lateral branch of the posterior rami of spinal nerves[2]
Artery[edit | edit source]
Posterior branch of posterior intercostal artery, deep cervical artery and muscular branches of vertebral artery.[2]
Function[edit | edit source]
Spinalis thoracis works with the other spinalis and the other erector spinae muscles: longissimus and iliocostalis to produce thoracic extension as well as lateral flexion and rotation of the spine[1].
