The nuchal ligament extends from the external occipital protuberance on the skull and median nuchal line to the spinous process of the seventh cervical vertebra in the lower part of the neck. [1] From the anterior border of the nuchal ligament, a fibrous lamina is given off.
The nuchal fascia is a fascia covering the autochthonous musculature of the neck as a part of the cervical fascia.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 s
Horizontal extent - From ligamentum nuchae when traced forward, the fascia splits and encloses trapezius, reunites and form roof of posterior triangle of neck; again splits and encloses sternocleidomastoid, reunites and forms the roof of anterior triangle. Vertical extent -

nuchal ligament (or ligamentum nuchae) and spinous processes of vertebrae C7 through T3 upper borders of 2nd through 5th ribs: intercostal arteries: 2nd through 5th intercostal nerves: elevates ribs(II to V), aiding in inspiration: 2 1 hemidiaphragm, lumbar/costal/sternal part Torso, Chest, Left/right
The long spinous process of C7 is thick and nearly horizontal in direction. It is not bifurcated, and ends in a tubercle that the ligamentum nuchae attaches to. This process is not always the most prominent of the spinous processes, being found only about 70% of the time, C6 or T1 can sometimes be the most prominent.

The nuchal lines are four curved lines on the external surface of the occipital bone: The upper, often faintly marked, is named the highest nuchal line, but is sometimes referred to as the Mempin line or linea suprema, and it attaches to the epicranial aponeurosis. Below the highest nuchal line is the superior nuchal line.
