Innervation of the defence gland in P. schultei by N. anterior SOG as revealed by anterograde tracing with cobalt solution. a Anterior part of the defence gland contacted by two nerve branches of the filled N. anterior SOG. Arrowhead indicates an additional nerve branch innervating adjacent muscles but not the gland. b Section from the middle part of the defence gland. Scale bars: (a) 250 mm; (b) 100 μm
