  • cloacal ganglion
    • A pair of neuronal ganglia in the adult male tail, lying on either side of the proctodeum, but not found in the hermaphrodite.
  • gubernaculum
    • A sclerotized cuticular structure at the base of the male tail fan which houses the retracted spicules and guides the eversion of the spicules through the anus.
  • cloaca
    • a feature of the male tail, caudal to the proctodeum, where the vas deferens and the intestine open out jointly near the tail tip to discharge their contents.
  • hook
    • A small lump on the gubernaculum of the male tail. This structure lies on the ventral surface just anterior and central to the base of the spicule openings and contains a sensory structure called the hook sensillum.
  • PHCL
    • Neuron, striated rootlet in male, possibly sensory in tail spike
  • PHCR
    • Neuron, striated rootlet in male, possibly sensory in tail spike
  • dorso-rectal ganglion
    • the ganglion that lies above and behind the rectum in the tail, in close continuity with the anal hypodermal ridge. It contains 3 neuron cell bodies (DVA, DVB and DVC) that send their neuronal processes into the ventral nerve cord via dorso-rectal commissures that encircle the anus. The ganglion contains no local neuropil in the hermaphrodite. In the adult male tail, this ganglion gains additional neurons and some local neuropil.
  • cuticle
    • a rigid external coating which is secreted by the hypodermis, seam and some transitional epithelial cells which covers the outer body, the major openings into the body cavity from the exterior, and two large sensory bristles, the male spicules. The cuticle of the spicules, the hook, and of some portions of the spicule channels is especially rigid and is probably sclerotized. Similar sclerotic features are occasionally noted in the ventral surface of the male tail fan.

  • ray
    • male sensory organ; nine bilateral pairs of finger-like rays (numbered 1 to 9, Left/Right) radiate from the tail and are embedded in a cuticlar fan.
  • lumbar ganglion
    • The left and right lumbar ganglia lie behind the pre-anal ganglion in the tail, in lateral positions. Each contains 12 neuron cell bodies that send most of their neuronal processes into the ventral nerve cord via lumbar commissures and the pre-anal ganglion. There is no local neuropil in these ganglia in the hermaphrodite, instead they form most synapses in the pre-anal ganglion. Most lumbar neurons have sensory functions. In the adult male tail, these two ganglia gain many additional neurons and have some local neuropil. The lumbar neurons lie in close association with the lateral hypodermis, and most are posterior to the anus.
