What are the intertransversarii muscles?
The intertransversarii muscles function to flex the spine laterally by approximating adjacent transverse processes. They also help to stabilize adjacent vertebrae during large spinal movements. The thoracic intertransversarii muscles are small and are usually only present in the lower thoracic region.
What is origin and insertion for intertransversarii?
Anterior intertransversarii colli originate from the anterior tubercles of transverse process of one cervical vertebra and insert onto the anterior tubercle of transverse process of the adjacent vertebra.
What does the Interspinalis muscle do?
The interspinales muscles are innervated by the medial branches of the posterior primary divisions of spinal nerves. The interspinales muscles function to extend the spine and may act as proprioceptive organs (Bogduk, 2005).
What Innervates the Interspinales and the intertransversarii?
Innervation. Like the other intrinsic muscles of the back, interspinales muscles are innervated by the posterior rami of the respective spinal nerves.
What does intertransversarii mean?
Intertransversarii are small muscles of the back found between contiguous transverse processes of the cervical, lumbar, and some thoracic, vertebrae. They comprise the deepest layer of the deep (autochtone) back muscles, along with interspinales and levatores costarum.
Where is the longus colli?
neck
The left and right longus colli muscles (see Fig. 4-6) are located along the anterior aspect of the cervical vertebral bodies. Each of these muscles consists of three parts: vertical, inferior oblique, and superior oblique. Together the three parts of this muscle flex the neck (Cagnie et al., 2010).
Where is the intertransversarii?
What is the origin of the quadratus Lumborum?
The Quadratus Lumborum (QL) is the deepest back muscle and originates from the iliac crest and inserts on the transverse process of lumbar one through five and the lower part of the twelfth rib. The QL muscle is flattened and has a quadrangular shape.
Where is the Iliocostalis Lumborum?
Iliocostalis is a dorsal muscle situated deep to the fleshy section of serratus anterior. Iliocostalis lumborum is the lower (lumbar) portion of that muscle. Injury to iliocostalis lumborum may be indicated by pain concentrated in the lower back or pain in the buttocks.

What Innervates the longus colli?
The longus colli muscle is a prevertebral muscle of the neck that is innervated by the anterior rami of C2-C6 from the cervical plexus. Longus colli is a weak flexor the cervical spine and when contracting unilaterally it tilts and rotates the cervical spine to the ipsilateral side.
What is the longus colli?
Description. Musculus longus colli or Musculus longus cervicis is one of the four deep cervical flexor muscles (AKA anterior cervical muscles) together with Longus Capitis, Rectus Capitis Anterior and Rectus Capitis Lateralis. It consists of three portions: Superior Oblique. Inferior Oblique.
