WebNov 7, 2024 · The otic placode, a thickening ectodermal layer of an embryo, is the first visible indication of inner ear development. Once the otic vesicle arises from the otic placode, neuroblasts delaminate from the otic vesicle and coalesce to form the statoacoustic ganglion (SAG). The SAG supplies the sensory innervations to the inner ear.

WebAbstract Statoacoustic ganglion (SAG) neurons send their peripheral processes to navigate into the inner ear sensory organs where they will ultimately become post-synaptic to mature hair cells.
