THE DILATABLE RING CANALS OF THE OVARIAN CYSTOCYTES OF HABROBRACON JUGLANDIS

The canals connecting the ovarian cystocytes of Habrobracon juglandis are enclosed by a ring made up of eight leaves. Each leaf is composed of a monolayer of between and 70 short parallel microtubules which may be derived from the mid-body. The sliding of certain leaves past one another allows the ring to dilate as the cystocyte grows.
