Type: Polymodal (motor neuron, interneuron)
In MoW: DVB
Male Wiring Project: DVB
In Wormbase: DVB
Lineage: K.p
Location: Dorsorectal ganglion
Description: An excitatory GABAergic motor neuron/interneuron located in dorso-rectal ganglion. Innervates enteric muscles. Born postembryonically from K rectal epithelial cell; at late L1 stage K rectal epithelial side (on the left side of rectum) divides to generate DVB (K.p) and K.a which acts as the new rectal epithelial cell.
Neurotransmitter/ Neuropeptide:
- GABA
(Eastman et al., 1999)
Innexin expression:
- INX-3
- INX-7
- INX-10
- INX-13
- UNC-7
- UNC-9
(Altun et al., 2009)
Receptor expression:
Function:
- Defecation. AVL and DVB are excitatory GABAergic motor neurons for the enteric muscles (Avery and Thomas, 1997; McIntire et al., 1993). Together with AVL, activates expulsion muscle contraction (E.p or EMC)
