Fine structure of a proprioceptor in the body wall of the marine nematode Deontostoma californicum Steiner and Albin, 1933 (Enoplida: Leptosomatidae).

The structure of a proprioceptor in the lateral hypodermal chords of Deontostoma californicum has been studied by light and electron microscopy. It is comprised of a sensory cell provided with a cilium situated in a terminal invagination. An accompanying dendrite forms a synaptic junction at the distal end of the sensory cell. This is the first fine structural description of this proprioceptor in the Enoplida.
