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.

G cell

Ventral ganglion neuroblasts present at hatching, located near the excretory pore.

distal tip cell

somatic cell that situates at the tip of a gonad arm.

hermaphrodite distal tip cell

somatic gonad cell that situates at the distal tip of the hermaphrodite gonad.

Y cell

Rectal cell at hatching, becomes PDA in hermaphrodite, postembryonic blast cell in male

spicule neuron
