Neutrophil blood cell. Light micrograph of a neutrophil leucocyte (white blood cell) surrounded by erythrocytes (red blood cells). The neutrophil (centre) has a characteristic lobed nucleus (blue). This usually consists of five lobes connected by fine strands of nuclear material. In the neutrophils of females, the cell's condensed X chromosome, or Barr body, is occasionally visible as a drumstick-shaped appendage. This is known as the drumstick chromosome and is seen here at the centre of the cell. Neutrophils are the most common white blood cell and they engulf and digest invading microorganisms. Phase contrast technique. Magnification: x1000 at 35mm size.
