Sagittal closeup section at C6–C7 showing
a screw that transgresses and partially fractures the inferior
articular process of C6. Both ganglia are accommodated in deep
furrows at the anterior surface of the articular masses. This
recessing of the ganglia allows the vertebral artery to take a
straight course towards the transverse foramen of C6. The plate
snugly fits on the inferior articular process of C6 whereas but at
C7 there is a considerable gap between the plate and the articular
mass. The tip of the screw is in direct contact with the C7
ganglion. Note that the motor root is located at the lower pole of
the dorsal root ganglion. At C7 the vertebral artery swings
anteriorly and laterally because it normally is runs outside the
transverse foramina of C7. |
