The endolymphatic sacs in embryos of Amphisbaena darwini

Abstract

Endolymphatic sacs of amphibians and reptiles are usually located inside the cranial cavity, posterior to the brain and dorsal to the foramen magnum (Wever, 1978, 1985). They are connected with the sacculus of the inner ear by means of endolymphatic ducts that pierce the internal bony wall of the otic capsules.
