Pterygospinous ligament

The pterygospinous ligament, called the pterygospinous ligament, is located in the anteromedial part and looks like a small cushion. Posteriorly, it connects in front with the cervical ligament, lies superficially in relation to neighboring organs, under the muscular and between the aponeuroses. Located behind the lumbar-thoracic spine, across both transverse processes of the cervical vertebrae. It articulates in the lumbar spine with the transverse spinous, interspinous and intertransverse joints. The pterygospinous ligament is supplied by the sympathetic and parasympathetic divisions of the autonomic nervous system. Its functions are to deflect the body sideways with fixed lower limbs. It also provides stability to the torso when turning the head and turning the body.
