Basal body formation occurs most prominently in the equatorial region of the predivision cell. A new basal body begins to develop perpendicular to the mature basal body at its proximal anterior surfac...

Electron micrograph of corn stunt spiroplasma (CSS) in the wall of the filter chamber (part of the alimentary canal) and in the hemolymph (he) of a vector leafhopper D. gelbus. Note the mainly pleiomo...

Collagen fibrils and mineralization in the external layer of Fundulus heteroclitus scale. The external layer is the second of three layers closest to the dermis of an elasmoid. It is composed of thin ...

Two electron micrographs of smooth muscle cells in a small artery, surrounded by a light gray zone of interspaces composed of an elastic fiber and collagen-rich basement membrane. The elastica intern...

Quick-frozen deep-etched preparation of skeletal muscle tissue shows the muscle fiber and associated extracellular components. The basement membrane (labeled basal lamina) lies adjacent to the undulat...

The image shows an anchor cell (red) in the developing female reproductive system of C. elegans pushing through the basement membrane (green) that surrounds it. This type of invasion is also often see...

Scanning electron micrograph of Mountain Cedar pollen. This pollen causes Mountain Cedar allergy that cause itchy, runny nose, sneezing, nasal blockage, excess tearing and itchy eyes in people from ...

During division new basal bodies develop accessory fibers and begin to move apart to take up a position equidistant between the older complexes. The new kinetodesmal fiber seems to be associated with ...
