HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.
Term:Abnormal pyramidal tract morphology

Accession:HP:0002062 term browser browse the term
Definition:Any structural abnormality of the pyramidal tract, whose chief element, the corticospinal tract, is the only direct connection between the brain and the spinal cord. In addition to the corticospinal tract, the pyramidal system includes the corticobulbar, corticomesencephalic, and corticopontine tracts.
Comment:The pyramidal tracts comprise both the corticospinal and corticobulbar tracts.
Synonyms:exact_synonym: Abnormality of the pyramidal tracts;   Morphological abnormality of the pyramidal tract
 related_synonym: Pyramidal tract disease
 alt_id: HP:0012445
 xref: UMLS:C4020859;   UMLS:C4021761
