Type: Motor neuron in the hermaphrodite
Motor neuron and interneuron in the male
Connectivity:
- In MoW: PDB
- In WormWiring: PDBh
- In Nemanode: PDB
In Wormbase: PDB
Lineage: P12.apa
Location: Preanal ganglion
Description: Born postembryonically. Sends process towards tail which turns around and joins dorsal cord in hermaphrodites. PDB process exhibits elaborate branching in the male (Jarrell et al., 2012; WormWiring). PDB has identical connectivity to male-specific neuron PDC.
Neurotransmitter/ Neuropeptide:
- Acetylcholine
(Pereira et al., 2015)


Innexin expression:
- Makes gap junctions to multiple partners but major gap junctions are to EF1, EF2, PDC, AVL, PHB, DA08
(Jarrell et al., 2012; WormWiring)

Receptor expression:
- UNC-8, a DEG/ENaC family member homologous to subunits of a candidate mechanically gated ion channel
(Tavernarakis et al., 1997)
Function:
- Innervates posterior dorsal body wall muscles. Likely controls mating posture in males along with male-specific PVV and PDC neurons.
(Koo et al., 2011)
Connectivity:
- At CGC:
