GapjunctFIG 3: Gap junctions seen in thin sections by TEM.
A. High magnification view of adult dorsal nerve cord; white arrowhead shows chemical synapse; black arrowhead shows GJ between muscle arms. BWM, bodywall muscle; hyp, hypodermis. (Image source: [Beth Chen; Hall lab archive] N2U Z152.) Scale bar is 0.5 micron.
B. Wild type adult amphid nerve; black arrowheads show small GJ between two amphid dendrites (den). (Image source: [Hall] N513A J3 F579.) Scale bar is 0.5 micron.
C. Adult pharynx in unc104-2 animal showing AJ (white arrows) and GJ (black arrowhead). Both junctions occur between a pharyngeal muscle (pm) and a marginal cell (MC). (Image source: [Hall] U3 M498.) Scale bar is 0.5 micron.
D. Adult excretory canal showing two GJs connecting the excretory canal process to hypodermis (hyp)(black arrowheads). (Image source: [Matthew Buechner; Hall lab archive]). Scale bar is 0.5 micron.
