Posterior part of a vertebra that consists of a pair of pedicles and a pair of laminae, and supports seven processes: four articular processes, two transverse processes one spinous process[WP]. ZFA: A neural arch encloses the neural canal and typically meets its partner to form a neural spine. [ http://en.wikipedia.org/wiki/Vertebral_arch ]
Synonyms: dorsal arcocentrum arcus vertebrae (vertebralis) arcus vertebra arcus vertebrae

The neural arch can be a replacement ossification of the basidorsal cartilage or can form directly in membrane bone
Bony arch perched on the vertebral centrum; successive arches enclose the neural canal that surrounds and protects the spinal cord dorsally.[AAO]
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]
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)
(...) certain common components [of vertebral structure] are found in nearly all vertebrate. A representative vertebra has a vertebral arch or neural arch, which extends dorsally around the spinal cord.[well established][VHOG]
