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.
