CELL TYPE LINEAGE LOCATION NEUROTRANSMITTER ASSOCIATED GLIA

M1

Pharyngeal motor neuron
MS.paapaaa

Pharynx posterior bulb

Possibly Ach. (Duerr J. et al, 1994)

Express neuropeptide-like protein NLP-3 (Nathoo A. et al 2001).
None

DESCRIPTION

The cell body of M1 is located subdorsally between the muscle and right marginal cell. A single process runs anteriorly in this position to the nerve ring where it then joins the dorsal nerve cord. Upon reaching the level of pm1, the process splits into two to send a vesicle-filled process to each of the subventral nerve cords, synapsing on pm1 and pm2 before reaching the cords. These then run posteriorly for a short length and form synapses on pm2 and pm3 (Albertson D. J. and Thomson J. N., 1976).

Functions: Unknown or redundant (Avery L, and Thomas J. H., 1997).

Receptor expression: Expresses glutamate receptor subunits, GLR-2 (Brockie P.J. et al 2001). Suggested to express a subunit of the glutamate-gated chloride channel, AVR-14 (Aptel N. et al, 2001).
