Scanning electron micrograph of the lumenal surface of the toad bladder shows the boundaries of four polygonal squamous epithelial cells surrounding a mitochondrial-rich cell bearing short globular mi...

Filaments extend from microvilli of the epithelial cells in the intestine of the bat, Moytis lucifugus in these two high magnification electron micrographs. These filaments, which are 2.5-5nm thick, ...

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...

Transmission electron micrograph showing collagen fibrils exhibiting focal swelling and loss of periodic cross banding in the trabecular meshwork of a person with glaucoma. The trabecular meshwork is ...

Transmission electron micrograph showing collagen fibrils in longitudinal view from a patient with glaucoma. The a-e banding is visualized by uranyl acetate staining of charged amino acid residues in ...

Collagen fibrils in the basal plate of Fundulus heteroclitus scales. The basal plate is made of thick collagen fibrils about 100 nm in diameter, which are organized into a plywood-like structure. Note...

This section of Conchophthirus is at the edge of the cortex showing the striated fibers and microtubules that attach to ciliated basal bodies. In particular, enlarged glancing longitudinal views of bo...

Figure 301 from Chapter 12 (Centrioles) of 'The Cell' by Don W. Fawcett M.D. Centrioles are usually positioned so that their long axes form a right angle. Their perpendicular orientation is maintained...

This section of Conchophthirus is at the edge of the cortex showing the striated fibers and microtubules that attach to ciliated basal bodies. In particular, enlarged glancing longitudinal views of bo...

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 ...
