How Do You Spell STRIA VASCULARIS?

1. The Stria Vascularis is a specialized region in the cochlea of the inner ear that plays a crucial role in the physiology of hearing. It is a thin, highly vascularized strip of tissue located along the lateral wall of the scala media, one of the three fluid-filled compartments in the cochlea.

   The primary function of the Stria Vascularis is to maintain the ionic composition of the endolymph, the fluid that fills the scala media. It accomplishes this by actively secreting potassium ions into the endolymph and absorbing sodium ions from it. This unique process creates a high concentration of potassium ions in the endolymph, which is necessary for the proper function of hair cells in the organ of Corti, responsible for converting sound vibrations into electrical signals.

   In addition to its role in maintaining the endolymph, the Stria Vascularis also provides the energy needed for the sensory cells in the cochlea to function effectively. It contains a dense network of blood vessels that supply it with oxygen and nutrients to sustain its metabolic demands.

   Clinically, dysfunction of the Stria Vascularis can lead to conditions such as endolymphatic hydrops or Meniere's disease, characterized by fluctuating hearing loss, tinnitus, and vertigo.

   In summary, the Stria Vascularis is a specialized strip of tissue in the cochlea that helps regulate the ionic composition of the endolymph and provides the necessary energy for the auditory system to function correctly.

2. Vascular stripe, a portion of the upper part of the ligamentum spirale cochleae containing numerous small blood-vessels.

Common Misspellings for STRIA VASCULARIS

The word "Stria Vascularis" has a Latin word origin.

"Stria" comes from the Latin word "stria", meaning "furrow" or "groove". It is derived from the Proto-Indo-European root "striko-", which means "to stroke" or "to rub".

"Vascularis" is also derived from the Latin word "vasculum", which means "vessel" or "small container".

Therefore, "Stria Vascularis" can be translated as "vascular groove" or "vascular furrow". In anatomy, the term refers to the highly vascularized region in the cochlea of the inner ear.
