WebPharyngeal arch. The pharyngeal arches, also known as visceral arches, are structures seen in the embryonic development of vertebrates that are recognisable precursors for many structures. In fish, the arches are known as the branchial arches, or gill arches. In the human embryo, the arches are first seen during the fourth week of development. WebFeb 18, 2005 · The heart rates of embryos within eggs were monitored as the young fish were exposed to sounds in the range of 100 to 1200 Hz at lev- els of 80 to 150 dB (re 1 µPa at 1 m) on each day of incubation. We found that, from 3 d after fertilisa- tion, the heart rates of the embryos significantly increased when exposed to sound.
