Transmission electron micrograph of a cross section through the nucleolus from a Chinese hamster spermatogonium revealing a complex distribution of regions of varying granular textures.

Electron micrograph showing fingerprint like ridges called microplicae on the surface of fish skin epidermis from the neon tetra. These ridges offer mechanical reinforcement against trauma and help ho...

Pseudopods jut out from this polymorphonuclear leucocyte of the guinea pig to enable amoeboid motility. Organelles are initially excluded as the pseudopod first forms, but they flow in as the pseudopo...

A thin section through a macrophage from interstitial tissue of the testes of the opossum. These cells are characterized by extensive folding of the cell surface, some of which appear to have captured...
