This electron micrograph shows the basal lamina along the midgut epithelium of the flea. Unlike the vertebrate basal lamina, which appears as a homogenous layer, the basal lamina in insects often app...

This electron micrograph shows the basal lamina as a thin gray moustache following parallel along the basal membrane of epithelial cells from human corneal epithelium. In this tissue, the basal lamin...

Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

This electron micrograph shows the endothelium and the underlying Descemet's membrane of the human cornea. Descemet's membrane is an unusually thick and structurally specialized example of basal lami...

Sarcolemma of skeletal muscle prepared by a quick-freeze deep-etch method also shows the basement membrane (lamina externa, labeled here as the basal lamina) associated with the muscle fiber. This me...

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...

Schwann cells in peripheral nerves secrete a layer similar to the basal lamina called the lamina externa, boundary layer, or basement membrane. In this micrograph, the lamina externa surrounds the Sc...

The images in this group show electron micrographs of epidermal and mesophyll cells in thin sections of maize leaves infected with Maize mosaic virus (MMV, Rhabdoviridae). MMV virions are bullet-shape...

These two micrographs show the outer cell surface of the epithelial cell border in intestine (upper) and stomach (lower) tissue. This surface, called the glycocalyx, is composed of negatively charged...
