salivary gland body primordium [FBbt_00005512]

Primordium that will form the secretory body of the embryonic/larval salivary gland. This primordium is first apparent as two epidermal placodes on the medial surface of the labial buds during stage 11. These placodes invaginate during embryonic stage 11 to form simple tubes on each side of the embryo that are positioned approximately along the dorso-ventral axis. Once internalized, the primordia migrate posteriorly during embryonic stage 12. They fuse to the developing salivary gland common duct by stage 13 and shortly after begin to show signs of secretory activity.
