Description

The P-face of the ciliary membrane at the base of the cilium has 9 triple rows of IMPs in register with the 9 doublets of the internal axoneme. It is thought that these IMPs may be sites of calcium influx into the base of the cilium for regulating ciliary activity. Also, trichocyst docking sites. TEM taken on 1/6/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0.25µm. There is a high resolution version of this image in the library (CIL:39317) which is available for quantitative analysis.
