In the cervical region the fibres of the interspinous and nuchal ligaments pass in an anteroc
ranial direction: they act against diminishing of the cervical lordosis. In the thoracic region,
longitudinal bundles of fibres connect the tops of the spinous processes; they act against an augmentation of the thoracal kyphosis. Between thoracal kyphosis and lumbal lordosis there is no
exact course of the fibres of the interspinous ligts. ("thorakolumbaler "Übergangsbereich"). In the
lumbar spine the fibres of the interspinous ligts., being very strong, pass in a posterocranial
direction. They have the function of limitation the range of flexion ventrally and of limiting backwards - shifting of the cranial vertebra in dorsal-flexion.
In the lumbosacral segment additional fibres, arising from the top of the 5th lumbar spinous
process, pass in a posterocaudal direction and interlace with the thoracolumbar fascia , whose fibres
form — below the 4 th lumbarvertebra — ascissor - latticed structure. The supraspinous ligt. lies
superficially to the thoracolumbar fascia. Its fibres pass several spinous processes. I t ends caudally
at the 4th lumbar spinous process.
