Transverse process - Processus transversus

Description

The transverse processes, two in number, project one at either side from the point where the lamina joins the pedicle, between the cranial and caudal articular processes.

In cervical vertebrae, their is some particularities:

  • The transverse processes are perforated toward their base by the transverse foramen for passage of vertebral vessels and nerve.
  • There is cranioventral branch on the transverse process from C3 to C7, called the ventral tubercle. This ventral tubercle is enlarged on C6 (ventral plate)
  • There is also a caudoventral branch of transverse process from C3 to C7 called the dorsal tubercle.
