external definition

A neural arch encloses the neural canal and typically meets its partner to form a neural spine. The neural arch can be a replacement ossification of the basidorsal cartilage or can form directly in membrane bone.[TAO], Bony arch perched on the vertebral centrum; successive arches enclose the neural canal that surrounds and protects the spinal cord dorsally.[AAO], the dorsal bony and/or cartilaginous part of a vertebra, consisting of a pair of pedicles, a pair of laminae, and seven processes (four articular processes, two transverse processes, and one spinous process)
