- PHD
A neuron belonging to a class of 2 bilateral, cholinergic, peptidergic, male-specific, ciliated neurons generated by transdifferentiation from a male PHso1 glial cell in the late L4 larval stage of a male C. elegans animal.
- primary spermatocyte
A diploid immature germ cell which forms in the gonad when a spermatogonial stem cell buds off from the rachis to form a single cell that quickly enters metaphase I and divides to form secondary spermatocytes attached to a residual body.
- socket cell
An interfacial epithelial cell which forms a distal cap on a sheath cell to bind the sheath of a sensillum to the neighboring hypodermis, via adherens junctions. There is often a narrow opening through the socket from the exterior into the sheath channel, allowing ciliated dendrites to be exposed to the external environment. The socket cell functions similarly to a glial cell.
- syncytium precursor
cell that is mononuclear and has a strong potential to fuse with other cell(s) to form a multinucleated cell.
- spermatocyte
A cell which gives rise to spermatids by meiosis.
- command interneuron
a type of interneurons whose synaptic output represent a final common pathway to motor neurons. The synaptic activities of command interneurons lead directly to the control of locomotion.
- secondary spermatocyte
A haploid immature germ cell which forms in the gonad by the division of a diploid primary spermatocyte. It undergoes a second meiotic division to complete meiosis, at which time the daughter cells detach from the residual body to become spermatids.
- germline blastomere
Embryonic cell that has the developmental potential to generate a germ cell.
- spike
a binuclear syncytium, used during embryogenesis to make tail spike, then die.
