Description

Image of the scopula, the stalk forming region at the aboral end of the cell body of Opercularia coarctata. A group of basal bodies each gives rise to a modified cilium that gives rise to a cylinder of striated fibrous 'straws' that occupy the lumen of the non-contractile stalk. This image shows a basal body of the trochal region, the end of the empty nascent food vacuole tube that is surrounded by lamellar microtubules that arise from the cytopharynx, the macronucleus, myonemes, and a perioral kinetid.

Technical Details

TEM taken on 6/10/69 by R. Allen with Philips 300 operating at 60kV. Neg. 11,800X. Bar = 1.0µm. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections prepared at approximately 75nm thickness.
