Around its second to third week, the developing embryo consists of three layers: ectoderm, mesoderm, and endoderm. The first part of the ear to develop is the inner ear, [ 19 ] which begins to form from the ectoderm around the embryo's 22nd day, [ 18 ] derived from two thickenings called otic placodes on either side of the head.
Prior to implantation, the embryo remains in a protein shell, the zona pellucida, and undergoes a series of rapid mitotic cell divisions called cleavage.
