DPhaSUPFIG 6: Ventral g1 gland ducts and processes.
A. Illustrations showing positions of dorsal and ventral g1 gland cell bodies and processes. The gland processes travel anteriorly within the three pharyngeal nerve cords. The pharyngeal nerve cords contain neuronal and non-neuronal cell types in close apposition without intervening basement membranes. Arrow indicates approximate position of TEM sections in B&C.
B. Transverse TEM section of L2 larva showing ventral g1 gland processes and ducts within the left and right subventral nerve cords. (Image source: N2 L2 28-14 [D. Riddle] 836.)
C. Transverse TEM section of dauer showing ventral g1 gland processes within the left and right subventral nerve cords. Gland process diameters are shrunken in the dauer compared to L2. (Image source: N2 starved dauer 50-2-1 [D. Riddle] 350M.)
Abbreviations: nc-d, dorsal nerve cord; nc-svl, left subventral nerve cord; nc-svr, right subventral nerve cord.
