A blood smear, peripheral blood smear or blood film is a thin layer of blood smeared on a glass microscope slide and ... the monolayer is viewed under a microscope ...
Elliptocytes, also known as ovalocytes or cigar cells, are abnormally shaped red blood cells that appear oval or elongated, from slightly egg-shaped to rod or pencil forms. They have normal central pallor with the hemoglobin appearing concentrated at the ends of the elongated cells when viewed through a light microscope.
Scanning electron microscope image of pollen (false colors) Microscopic examination in a biochemical laboratory. Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye (objects that are not within the resolution range of the normal eye).

Histologic specimen being placed on the stage of an optical microscope. Human lung tissue stained with hematoxylin and eosin as seen under a microscope.. Histology, [help 1] also known as microscopic anatomy or microanatomy, [1] is the branch of biology that studies the microscopic anatomy of biological tissues.
Rouleaux of red blood cells under the microscope is an artifact which occurs when the blood sample at the edge of the coverslip [15] starts to dry out; where a large number of red blood cells clump together; or when the blood starts to clot when contacted with the glass. These artifacts are observed in only small, selected areas on the slide ...
Transmission electron microscope image of a capillary with a red blood cell within the pancreas. The capillary lining consists of long, thin endothelial cells, connected by tight junctions . The vessels on the arterial side of the microcirculation are called the arterioles , which are well innervated, are surrounded by smooth muscle cells, and ...
Through the work of Karl von Vierordt, Louis-Charles Malassez, Karl Bürker and others blood cell concentration could by the late 19th century be accurately measured using a blood cell counting chamber, the hemocytometer, and an optical microscope. [3] [4] Until the 1950s the hemocytometer was the standard method to count blood cells. [5]
In vivo (within the blood vessel), the codocyte is a bell-shaped cell. It assumes a "target" configuration only when processed to obtain a blood film. In the film these cells appear thinner than normal, primarily due to their pallor (by which thickness is judged on microscopy).
