The other main efferent pathways from the amygdala are the stria terminalis and anterior commissure. The central subdivision of the bed nucleus of the stria terminalis (BSTc) is sexually dimorphic. This pathway is called the ventral acoustic stria (VAS or, more commonly, the trapezoid body). The stria vascularis also contains pericytes, melanocytes, and endothelial cells. The basal cells separate stria vascularis from the underlying spiral ligament. Included in these metabolically active organs is the cochlear stria vascularis. Long term use of topical steroids may result in skin atrophy, stria, telangiectasia. The Great War Tour stretches over across the mountains between Lagazuoi and Sass de Stria. The underlying mechanism of ototoxicity may be impairment of ion transport in the stria vascularis. One of Chowning's most famous pieces is called "Stria" (1977). Diuretics are thought to alter the ionic gradient within the stria vascularis. Under magnification, gas bubbles and curved stria may be evident. The stria medullaris is a part of the epithalamus.
