Small intervertebral muscles that stabilize adjacent vertebrae and help maintain posture are called?
daser333 [38]

Multifidus

What is multifidus?

The transversospinal group of deep back muscles includes the semispinalis, rotatores, multifidus, and other short, triangular muscles. They are shorter than semispinalis but longer than rotatores, and they are the thickest muscles in the transversospinal group. On either side of the vertebral column, from the cervical to the lumbar spine, there is a multifidus. Cervical multifidus, thoracic multifidus, and lumbar multifidus are the three regional subgroups of the group.

The spinal column is extended by the multifidus muscles. They contribute to the lateral flexion of the spine as well as some rotation of the vertebral bodies away from the side of contraction.

Multifidus: a muscle in the fifth and deepest layer of the back that helps to erect and rotate the spine by filling in the groove on either side of the spinous processes of the vertebrae from the sacrum to the skull.
