- G1
Postembryonic blast cell, excretory socket in embryo
- blastocoel
The fluid-filled compartment inside the developing embryo at the onset of gastrulation, surrounded by the early blastomeres, into which some cells begin to migrate at gastrulation to create a multi-layered embryo. This internal space later is converted into the pseudocoelom as the embryo develops.
- HSNL
Herm. specific motor neurons (die in male embryo), innervate vulval muscles, serotonergic
- HSNR
Herm. specific motor neurons (die in male embryo), innervate vulval muscles, serotonergic
- URA
Neuron class of four ring motoneuron, non-ciliated endings in head, associated with OLQ in embryo.
