One of the brachial cranial nerves. The glossopharyngeal nerve (N.IX) receives sensory information from the and contains both sensory and motor fibres innervating the muscles in the first gill arch (third pharyngeal arch).

Lateral schematic of glossopharyngeal sensory ganglion adapted from Higashijima et al., 2000.

Lateral view of a 60hpf Tg(isl1:GFP) larvae labelled with anti-GFP. This confocal micrograph has been inverted and the different cranial motor nerves false coloured to creat a schematic diagram. The glossopharyngeal sensory ganglion is coloured in yellow.
