A portion of an isolated cilium exposing two rows of outer dynein arms arising from subfiber A of each doublet. The heavy chains of the dynein complex are linked to the microtubule by stems that can be seen in this micrograph. Thin protrusions link the dynein heavy chains to the adjacent doublet. Much of this cilium is still covered by the ciliary membrane. TEM taken on 6/7/88 by C. Schroeder with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0.1µm.A print of the negative was scanned and processed in Photoshop. This image is best used for qualitative analysis. A high resolution image (CIL:12035) is available for quantitative analysis. Additional information available at (http://www5.pbrc.hawaii.edu/allen/).
