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.
Comment:
[development-note] "The neural arch can be a replacement ossification of the basidorsal cartilage or can form directly in membrane bone"; [homology-note] "(...) 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]" xsd:string {date_retrieved="2012-09-17", external_class="VHOG:0001670", ontology="VHOG", source="ISBN:978-0030223693 Liem KF, Bemis WE, Walker WF, Grande L, Functional Anatomy of the Vertebrates: An Evolutionary Perspective (2001) p.270", source="http://bgee.unil.ch/"}; [taxon-note] "tiny neural arches present in Hagfish (which lack a true vertebraal column)."
