Last reviewed: 23.04.2024
The intermuscular muscles of the neck, chest and waist (mm., Interspinales cervicis, thoracis and lumborum) connect the spinous processes of the vertebrae with each other, beginning from the second cervical and below. They are better developed in the cervical and lumbar spine, which are characterized by the greatest mobility. In the thoracic part of the spine, the interstitial muscles are weakly expressed (may be absent).
Function: involved in extension of the corresponding parts of the spine.
Innervation: posterior branches of the spinal nerves.
Blood supply: deep cervical artery, posterior intercostal and lumbar arteries.
