intertransversarii muscles (anatomy)

Last reviewed 01/2018

The intertransversarii are one group of deep intrinsic back muscles. They are most developed in the cervical region. They originate from the transverse process of a given vertebra. They pass superiorly to insert into the transverse process of the vertebra that is immediately superior.

They are innervated by the posterior primary rami of the spinal nerves.

The action of the intertransversarii is to weakly flex the spinal column in a lateral direction.
