DESCRIPTION

One of 3 bilateral pairs of male-specific neurons (SPCL/R, SPDL/R, SPVL/R) that innervate the the left and right male copulatory spicules. SPCL/R are thought have both sensory (proprioceptive) and motor function. The dendrite of SPCL/R attaches to the dorsal spicule protractor muscles (dspL/R) via hemidesmosomes and the axon has outputs onto the dorsal and ventral protractor (vspL/R) muscles (Sulston et al., 1980).

See Glial Table for view of spicule organization.

Function: During mating, induces full insertion of the spicules into the vulva by promoting prolonged contraction of dspL/R and vspL/R muscles (Liu and Sternberg, 1995; Garcia et al., 2001; see "Mating Movie" in MALE HANDBOOK-INTRODUCTION to view spicule function in mating behavior).

Receptor expression: Unknown
