Fig. 8. Micrographs of LTKLI cells in M. sexta. (A) Whole mount of brain
of fifth instar larva. (B) Other focus and higher magnification shows varicose
branches of LTKLI neurons in larval brain. Note fibres in commissures. (C)
Unfused abdominal ganglion with LTKLI fibres in neuropils and entering from
anterior nerve root (arrow). Cell bodies are in other focal plane. (D)
Terminal abdominal ganglion with LTKLI cell bodies (arrows) and fibres in
neuropil. (E) Surface view of LTKLI endocrine cells of the midgut (e.g. at
arrows). The cells appear irregularly distributed partly because the intestine
became contracted at fixation. (F,G) Immunoreactive endocrine cells seen in
longitudinal view. Gut lumen is at bottom of panels. Scale bars: 100 µm
(A); 50 µm (B-D); 100 µm (E); 25 µm (F,G).
