In the ampullae of the starfish Astropecten irregularis extensions stretch from the main soma of the muscle cells down the seams of the ampullae into bulbs of tissue in the tube feet. Their terminations range from 0.2 to 4.0 μm in diameter. Here axons in tracts from the radial cord form synapses upon the extensions of the muscle cells. In sections examined with the electron microscope the extensions are distinguished from nerves by their central core of myofilaments, surrounded by clear… Expand
