neural arch

Go to external page http://purl.obolibrary.org/obo/UBERON_0003861

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 ]

development notes
  • The neural arch can be a replacement ossification of the basidorsal cartilage or can form directly in membrane bone
external definition

  • Bony arch perched on the vertebral centrum; successive arches enclose the neural canal that surrounds and protects the spinal cord dorsally.[AAO]
