Where is the intertransversarii muscles located?

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 does intertransversarii mean?

What muscles are involved in neck rotation?

What is the neck muscle that attaches to C3 C6?

anterior scalene muscle
The anterior scalene muscle is the most anterior of the scalene muscles. It arises from the anterior tubercles of the transverse processes of vertebrae C3-C6, and inserts onto the scalene tubercle and the superior border of the first rib.

Where is the longissimus Cervicis?

Longissimus cervicis is the middle portion of the muscle, located between longissimus capitis and longissimus thoracis. Longissimus thoracis, which is the most caudal part and the most prominent component of the erector spinae muscle group. Longissimus thoracis is divided into a lumbar and thoracic portion.

What are 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 do the intertransversarii muscles do?

Where are the neck muscles located?

Your neck muscles are at the front, back and sides of your neck. From the back, they begin just beneath the base of your skull and extend down near the middle of your back, around your shoulder blades. From the front, these muscles begin at your jaw and extend to your collarbone at the top of your chest.

Where is the Spinalis muscle?

spinalis muscle, any of the deep muscles of the back near the vertebral column that, as part of the erector spinae (sacrospinalis) muscle group, assist in extension (e.g., bending backward), lateral flexion (bending to the side), and rotation of the spine.

What nerves are affected by C5 C6 C7?

From the lateral cord, C5, C6, and C7 supply the pectoralis major and minor muscles, via the lateral and medial pectoral nerves, as well as the coracobrachialis, brachialis and biceps brachii, via the musculocutaneous nerve. The musculocutaneous nerve provides sensation to the skin of the lateral forearm.
