Anatomical terms of muscle |
Thetransversospinalesare a group ofmusclesof thehuman back.Their combined action is rotation and extension of thevertebral column.These muscles are small and have a poor mechanical advantage for contributing to motion. They include: the threesemispinalis muscles,themultifidus muscle,and therotatores muscles.
Location
[edit]The threesemispinalis muscles,span 4-6vertebral segments:
- semispinalis thoracis
- semispinalis cervicis
- semispinalis capitis
Themultifidus muscle,and spans 2-4 vertebral segments
Therotatores muscles,lie beneath the multifidus, and spans 1-2 vertebral segments
- rotatores cervicis
- rotatores thoracis
- rotatores lumborum
