Coloured scanning electron micrograph (SEM) of Clostridium botulinum bacteria (rod-shaped),
Cell infected with HIV. Coloured scanning electron micrograph (SEM) of HIV particles (yellow) budding from the membrane of a host cell (blue). HIV (human immunodeficiency virus) attacks CD4+ T-lymphocytes (specialised white blood cells), which are crucial in the body's immune system. It enters the cell and makes many copies of itself, which then destroy the cell as they emerge through its membrane. #anatomy #microscope #microscopic #medicine #medical #human
Bdelloidea are microscopic aquatic animals that are related to roundworms, found in freshwater and moist soil. Interestingly, a male has never been observed within the species; females reproduce exclusively by parthenogenesis (without fertilization).
☤ MD ☞ ☆☆☆ Colored scanning electron micrograph (SEM) of squamous cell carcinoma (cancer) cells from a human mouth. The many blebs (lumps) and microvilli (small projections) on the cells' surfaces are typical of cancer cells.
Our sense of balance is derived from a tiny stone in each ear, called an otolith (from Greek, literally "ear-stone"). The stones are built up in the inner ear from deposits of calcium carbonate crystals, seen here on the surface of an otolith.
infinity-imagined: Scanning electron micrographs of diatoms, microscopic algae that form the base of the food chain and produce of Earth’s oxygen. The beautiful base of the pyramid of biology, feeding our air, land and life.
