<unk>  is the proper name for the seventh cervical<unk> . The most distinctive characteristic of this<unk>  is the existence of a long and<unk>  spinous process which is papable from the skin surface, hence the name.
This spinous process is thick, nearly horizontal in direction, not bifurcated, but terminating in a tubercle to which the lower end of the ligamentum nuchae is attached.
The transverse processes are of considerable size, their posterior roots are large and<unk> , while the anterior are small and faintly marked;
the upper surface of each has usually a shallow sulcus for the eighth spinal nerve, and its extremity seldom presents more than a trace of bifurcation.
The foramen transversarium may be as large as that in the other cervical<unk> e, but is generally smaller on one or both sides;
occasionally it is double, sometimes it is absent.
On the left side it occasionally gives passage to the<unk> l artery;
more frequently the<unk> l vein traverses it on both sides;
but the usual arrangement is for both artery and vein to pass in front of the transverse process, and not through the foramen.
Sometimes the anterior root of the transverse process attains a large size and exists as a separate bone, which is known as a cervical rib.
