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/.

Definition:Normal muscle fibers are polygonal-shaped in cross section, are multinucleated, and have minimal amounts of endomysial connective tissue. In contrast, angulated (also known as angular) muscle fibers have long and narrow vertices (corners) with sharp edges and a pointed tip.
Comment:Muscle fibers showing neurogenic atrophy are compressed by neighboring non-atrophic fibers and may show an angulated appearance on a transverse section. See Figure 3A in PMID:32529201.
Synonyms:exact_synonym: Angular muscle fibers;   Angular muscle fibres
