What are the attachments of the Intertransversarii?
What are the attachments of the Intertransversarii?
Anterior intertransversarii colli muscles
| Origin | Transverse processes of cervical vertebrae |
|---|---|
| Insertion | Transverse processes of adjacent vertebrae |
| Action | Assists in lateral flexion of the cervical spine; Stabilizes cervical spine |
| Innervation | Anterior rami of spinal nerves |
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 Intertransversarii?
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.
What are the intertransverse ligaments?
The intertransverse ligaments consist of fibrous tissue joining transverse processes of adjacent vertebrae. In the cervical region, intertransverse ligaments are scattered fibers that are largely replaced by intertransverse muscles. The intertransverse ligaments become thin and membranous in the lumbar region.
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.
How do you stretch in Intertransversarii?
Intertransversarii exercises Lift your right arm and left leg from the floor and hold that position for ten seconds. Then return to the starting position. Now lift your left arm and right leg from the floor and hold it for ten seconds. Continue alternating in this manner for two sets of ten.
What are Interspinal muscles?
Interspinales muscles are short, paired muscles that belong to the deepest layer of the intrinsic muscles of the back. They extend between adjacent spinous processes of the vertebral column. Interspinales muscles serve to aid other intrinsic muscles of the back to extend the spine.
Where is the longus colli?
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).
What is Supraspinous ligament?
The supraspinous ligament or supraspinal ligament is a strong fibrous cord that connects together the apices of the spinous processes from the seventh cervical vertebra to 3rd or 4th lumbar vertebrae.
What are the attachments of the Interspinales?
Interspinales muscles
- Attachments: Connects the spinous processes of contiguous vertebrae, one on each side of the interspinous ligament, present only in the cervical and lumbar regions.
- Innervation: Dorsal rami of spinal nerves.
- Muscle type: Postural (type 1), shortens when stressed.
What do the interspinales muscles 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).
