It provides a smooth surface for joint movement, protecting the ends of long bones from wear at points of contact.Aristolochia: A plant genus of the family ARISTOLOCHIACEAE. Species of this genus have been used in traditional medicine but they contain aristolochic acid which is associated with nephropathy.

It is a common contaminant of clinical specimens, presumably from the skin of patients or attendants.Visual Acuity: Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain.
