The auditory organ, called the basilar papilla, shows a weak radial gradient (highest on the neural side) in prosensory cells near the base on embryonic day 7.
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. WebOct 19, 2016 · The Statoacoustic Ganglion (SAG) connects the inner ear to the brain and transmits hearing and balance information. SAG neurons are generated by a stepwise program that starts in the otic vesicle, the precursor of the inner ear.
WebMutant embryos display behaviors associated with vestibular deficits and showed reduced number of anterior statoacoustic ganglion neurons that innervate the utricle, the vestibular organ in zebrafish. Moreover, a shox2-reporter fish showed labeling of developing statoacoustic ganglion neurons in the anterior macula of the otic vesicle. WebThe statoacoustic ganglion was adjacent to the inner ear normally and it was larger in Salmo salar than in Salmo trutta. Although we expected that the ganglionic neurons would …
