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 pharyngeal pouch morphology

Accession:MP:0006031 term browser browse the term
Definition:any structural anomaly of the balloonlike diverticulae of the embryonic pharyngeal endoderm that line the inside of the branchial arches; these paired endodermal evaginations develop in a craniocaudal sequence between the branchial arches, e.g. pouch 1 lies between arches 1 and 2; in mammals, there are four well-developed pairs of pouches (the fifth and sixth pair is vestigial or absent); the pouch endoderm reaches the branchial groove ectoderm to form the double-layer branchial membranes that separate them
Synonyms:exact_synonym: abnormal branchial pouch morphology;   abnormal endodermal pouch morphology
