Accession:MP:0006021 term browser browse the term
Definition:any structural anomaly of the membrane which separates the cochlear duct from the vestibular canal, i.e. the endolymph of the scala media from the perilymph of the scala vestibuli; the Reissner membrane consists of squamous epithelial cells with microvilli toward the ductus, a basement membrane, and a thin layer of connective tissue toward the scala
Synonyms:exact_synonym: abnormal Reissner's membrane morphology;   abnormal membrana vestibularis ductus cochlearis morphology;   abnormal paries vestibularis ductus cochlearis morphology;   abnormal vestibular membrane morphology;   abnormal vestibular wall of cochlear duct morphology
