Intertransversarii Cervicis Posterior

musculi intertransversarii posteriores cervicis

The posterior cervical intertransversarii connect adjacent posterior tubercles and contribute to lateral cervical stabilisation and facet joint proprioception.

Nerve: Dorsal rami of cervical spinal nerves Blood Supply: Vertebral artery muscular branches Region: Neck
Anatomical Data

Origin, Insertion & Supply

OriginPosterior tubercle of each cervical transverse process
InsertionPosterior tubercle of the adjacent transverse process above
Nerve SupplyDorsal rami of cervical spinal nerves
Blood SupplyVertebral artery muscular branches
Biomechanics

Function & Actions

ActionsIpsilateral cervical lateral flexion; Postural stabilisation and proprioception of cervical facet joints
Clinical Relevance

Clinical Notes

Dysfunction contributes to cervicogenic dizziness. Their preservation in minimally invasive posterior cervical approaches reduces post-operative neck stiffness.

Palpation

Not palpable directly.
