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.

Definition:presence of small extra bone segments, usually of irregular shape and variable size, arising in fontanelles and/or adjacent to or along the cranial sutures, and formed from additional and separate centers of ossification of the cranium; in humans, Wormian bones are most frequently located in the lambdoid or coronal suture, and have been seen in the fontanelles, particularly the posterior fontanelle
Synonyms:exact_synonym: extra bones within cranial sutures;   intra sutural bones;   intrasutural bones;   islands of bone within cranial sutures or fontanelles
 broad_synonym: accessory skull bones;   supernumerary skull bones
