Cross section of a cilium showing the 9 + 2 axoneme. Two dynein arms, inner and outer, of heterogeneous appearance arise from the complete microtubule of each doublet. Spokes extend from the doublets ...

The highest concentration of parasomal sacs is found in the oral region associated with the three ciliary membranelles, called in Paramecium, the ventral amd dorsal peniculi and the quadrulus. This mi...

A high resolution view of cross-sectioned rows of basal bodies at the cortex of Nassula. Only a few basal bodies may have attached cilia as seen by the few cilia present in the upper right row. Basal ...

Cross section of a Coleps cilium showing the axoneme consisting of 9 doublet and 2 central microtubules. Doublets have a complete A subfiber and an attached B subfiber. Two dynein arms, outer and inne...

The monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise...

Time series light microscopy images illustrating a wound healing assay. A monolayer of MDCK (Madin-Darby Canine Kidney) epithelial cells is scratched to create a 'wound' about 300 micrometers in width...

The final morphogenesis of the cardiac outflow tract (OFT) depends on coordinated cell-cell interactions among the heart tip, migrating heart-anchoring cells (HANCs) and the dorsally growing cardiac o...

The final morphogenesis of the cardiac outflow tract (OFT) depends on coordinated cell-cell interactions among the heart tip, migrating heart-anchoring cells (HANCs) and the dorsally growing cardiac o...

A 3D reconstruction of the cardiac outflow tract (OFT)(horizontal rotation) from a stage-16 wild-type embryo stained for Ladybird early (Lbe; blue), Tinman (Tin; red), and the DE-Cadherin Shotgun (Shg...

Figure 320 & 321 from Chapter 13 (Cilia and Flagella) of 'The Cell' by Don W. Fawcett M.D. The disposition of the dynein arms along the length of the doublets is studied to best advantage in dissociat...
