• excretory cell
    • H-shaped cell associated with the excretory system, largest cell in C. elegans.
  • Excretory duct
    • The extracellular sinus formed by the excretory duct and pore cells.
  • excretory pore
    • The outlet of the excretory sinus to the exterior environment through the cuticle, on the ventral side of the head, just behind the nerve ring.
  • excretory system
  • excretory canal
    • Four processes (canals) of the excretory canal cell each contain a central collecting lumen which feeds to a central lumenal canal in the cell body; the central canal forms a specialized membrane to release fluids into the excretory duct. These five canals form a continuous H-shaped channel which extends almost the full length of the body, generally in contact with the lateral hypodermis and the pseudocoelom.
  • obsolete excretory
  • excretory socket cell
    • Excretory socket cell, links duct to hypodermis
  • excretory gland cell
    • gland cell of the secretory-excretory system, sends processes to ring, opens into excretory duct.

  • AIM
    • Neuron class of two interneurons with cell bodies in the ventral ganglion behind the excretory duct.
  • AVK
    • Neuron class of two interneurons with cell bodies situated in the ventral ganglion behind the excretory duct.
  • ventral ganglion
    • ganglion lies beside the nerve ring in the head, just anterior of the retrovesicular ganglion. It contains about 20 interneuron and motorneuron cell bodies that all send their neuronal processes into the ring. The cell bodies are divided into two groups by the intrusion of the excretory duct and canal. The cells are bounded by a basal lamina which physically separates them from the lateral ganglion even though they are adjacent to one another.
  • retrovesicular ganglion
    • Ganglion that lies at the anterior limit of the ventral nerve cord, near the ventral ganglion and nerve ring in the head posterior to the excretory pore. It is open and continuous with the region containing the motoneurons of the ventral cord. In the early L1 this ganglion holds 12 neuron cell bodies plus one neuroblast (Sulston and Horvitz, 1977; White et al., 1986). In the adult animal, the ganglion holds 20 neuron cell bodies.
