circular trunk visceral muscle primordium [FBbt_00017015]

Primordium of the circular visceral muscle of the trunk. Becomes distinct from the rest of the trunk mesoderm by stage 11 when two distinct layers of trunk mesoderm are apparent, the inner of which is the circular visceral muscle primordium. By stage 12, these cells form a palisade consisting of a dorsal row and a ventral row of tightly packed cells. These cells adhere to the anterior and posterior midgut rudiments as they extend. During dorsal closure they spread out to encircle the midgut.
