It proceeds the thoracolumbar fascia to the top (cranial).

The fascia itself is made of two parts: A superficial layer (lat.

: Fascia nuchae superficialis) and a deeper layer that is located among the Trapezius muscle and that sheaths the deeper cervical musculature from dorsal side.

Expanding laterally, the fascia also covers the dorsal musculature.

[1] In the middle of the deeper layer a bulge is resided – the nuchal ligament.
