MAMMALIAN PHENOTYPE - ANNOTATIONS

The Mouse Adult Gross Anatomy Ontology and Mammalian Phenotype Ontology are downloaded weekly from the Mouse Genome Informatics databases at Jackson Laboratories (ftp://ftp.informatics.jax.org/pub/reports/index.html). For more information about these ontologies, see the MGI Publications Page at http://www.informatics.jax.org/mgihome/other/publications.shtml.
Term:abnormal posterior longitudinal ligament morphology

Accession:MP:0030783 term browser browse the term
Definition:any structural anomaly of the ligament that runs within the vertebral canal along the posterior aspect of the vertebral bodies; it is attached mainly to the intervertebral (IV) discs and less so to the posterior aspects of the vertebral bodies from C2 (axis) to the sacrum, often bridging fat and vessels between the ligament and the bony surface; it weakly resists hyperflexion of the vertebral column and helps prevent or redirect posterior herniation of the nucleus pulposus of an IV disc; the posterior longitudinal ligament is well provided with nociceptive (pain) nerve endings and is a much narrower, somewhat weaker band than the anterior longitudinal ligament
Synonyms:narrow_synonym: ossification of the posterior longitudinal ligament of the spine
