The rotatores muscles can be divided into

• Rotatores cervicis
• Rotatores Thoracis
• Rotatores lumborum

Furthermore, these can be broken down into long and short muscles³.

• Long muscles span 2 vertebrae³.
• Short muscles span 1 vertebrae³.

Rotatores Breves

T1-T12: SP of vertebrae 2 above (it skips a vertebrae)⁴

Innervation

Spinal nn. (Posterior Rami)⁴

Action

• BIL: Extends T/S⁴
• UNIL: C/L Rotation of T/S⁴
