Definition: | A cranial placode which, once specified, invaginates to form an otic cup, which eventually separates from the surface ectoderm to form the otic vesicle or otocyst, a rounded structure without appar- ent polarity. As the otic placode invaginates into a cup neuroblasts delaminate from the anterior ventral aspect of the otic epithelium to give rise to neurons of the vestibulocochlear (statoacoustic) ganglion of cranial nerve VIII[NBK] |
