In human anatomy the Pars flaccida of tympanic membrane or Shrapnell’s membrane (also known as Rivinus’ ligament) is the small triangular flaccid portion of the tympanic membrane or eardrum. It lies above the malleolar folds attached directly to the petrous bone at the notch of Rivinus. On the inner surface of the tympanic membrane the chorda tympani crosses this area.It is named after Henry Jones Shrapnell.
