What is an action of the rotatores?

What is an action of the rotatores?

Action: extension of the thoracic vertebrae, proprioceptive transducers that monitor the position and movements of the vertebral column. Description: The Rotatores (Rotatores spinae) lie beneath the Multifidus and are found only in the thoracic region; they are eleven in number on either side.

Where is the Rotatores muscles?

Rotatores Muscles 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 the function of the multifidus muscle?

The multifidus muscle is an important stabilizer of the lumbar spine. It functions together with transversus abdominis and pelvic floor muscles for spine stability.

How many Rotatores muscles are there?

Anatomical terms of muscle 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.

What is the origin of the rotatores?

Rotatores muscles

Origin Rotatores breves: Transverse processes of vertebrae T2-T12 Rotatores longi: Transverse processes of thoracic vertebrae
Innervation Medial branches of posterior rami of spinal nerves
Blood supply Dorsal branches of posterior intercostal and lumbar arteries

What is the action of The rotatores in the back?

Rotatore Action. The entire intrinsic layer of the back, including the rotatores (and, as discussed above, the multifidus,) produces spinal extension, and assists with lateral flexion (side bending) and rotation (twisting).
