What are the Rotatores muscles?
The rotatores muscles are a group of 22 small, four-sided muscles found between the thoracic vertebrae on both sides of the spinal column. (I.e. there are 11 pairs of these muscles.) Each rotatores muscle originates from the traverse process of a thoracic vertebra.
What causes tight erector spinae?
The most common causes for these symptoms are inflammation, muscle strain, and muscle tear. Additionally, these muscles become tight if you live a sedentary lifestyle and your spinae erector muscles do the work to make up for weak abs, lats, and glutes.
What is the action of the rotatores?
|Origin||Rotatores breves: Transverse processes of vertebrae T2-T12 Rotatores longi: Transverse processes of thoracic vertebrae|
|Actions||Bilateral contraction: Extension of thoracic spine Unilateral contraction: Rotation of thoracic spine (contralateral)|
What are the 3 erector spinae muscles?
The term lumbar extensor is used colloquially to refer to the erector spinae muscle group, which is comprised of the iliocostalis lumborum, longissimus thoracis, and spinalis thoracis.
Where are the Rotatores muscles located?
Just below the multifidus lies the rotatores. Like the multifidus, the rotatores are small muscles located on either side of the spine. They are shaped like a quadrilateral and attach on the transverse process of the vertebrae.
What is spinae erector?
The erector spinae muscles are a group of long muscles that originate near the sacrum and extend vertically up the length of the back. The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine.
How many rotatores muscles are there?
The rotatores muscles (rotatores spinae muscles) lie beneath the multifidus and are present in all spinal regions but are most prominent in the thoracic region; they are eleven in number on either side.
