Teaching Science ElectroCity Not Free | 3D Human Anatomy | Products Brain & Nervous System Respiratory System Reproductive & Urinary Digestive System Histology A stained histologic specimen, sandwiched between a glass microscope slide and coverslip, mounted on the stage of a light microscope. Histopathology, the microscopic study of diseased tissue, is an important tool in anatomical pathology, since accurate diagnosis of cancer and other diseases usually requires histopathological examination of samples. Trained physicians, frequently board-certified as pathologists, are the personnel who perform histopathological examination and provide diagnostic information based on their observations. The trained scientists who perform the preparation of histological sections are histotechnicians, histology technicians (HT), histology technologists (HTL), medical scientists, medical laboratory technicians, or biomedical scientists. Sample preparation Medical students (EMIS) getting samples from a human stomach for future histological studies. 2012 at Instituto Nacional de Cardiologia in Mexico Fixing Frozen section fixation Embedding

Cell theory Human cancer cells with nuclei (specifically the DNA) stained blue. The central and rightmost cell are in interphase, so the entire nuclei are labeled. The cell on the left is going through mitosis and its DNA has condensed. The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells.The cell is the most basic unit of life.All cells arise from pre-existing, living cells. Microscopes Anton van Leeuwenhoek's Microscope from the 17th century with a magnification of 270x. Robert Hooke's microscope The discovery of the cell was made possible through the invention of the microscope. However, the first real invention and use of a microscope was by Anton van Leeuwenhoek. These microscopes could focus on objects the size of a wavelength or larger, giving restrictions still to advancement in discoveries with objects smaller than a wavelength. Discovery of cells Anton van Leeuwenhoek is another scientist who saw these cells soon after Hooke did.

Cell biology Understanding cells in terms of their molecular components. Knowing the components of cells and how cells work is fundamental to all biological sciences. Appreciating the similarities and differences between cell types is particularly important to the fields of cell and molecular biology as well as to biomedical fields such as cancer research and developmental biology. These fundamental similarities and differences provide a unifying theme, sometimes allowing the principles learned from studying one cell type to be extrapolated and generalized to other cell types. Processes Movement of proteins Endothelial cells under the microscope. Each type of protein is usually sent to a particular part of the cell. Extracellular and cell surface proteins destined to be degraded can move back into intracellular compartments upon being incorporated into endocytosed vesicles, some of which fuse with lysosomes where the proteins are broken down to their individual amino acids.

About | SMILE Are you looking for new ways to teach kids about math and science? Do you want activities that meet you where you live, whether your “classroom” is an active volcano, the shark tank at the local aquarium, or your own kitchen table? You’ve come to the right place. Howtosmile.org is collecting the best educational materials on the web and creating learning activities, tools, and services – all designed especially for those who teach school-aged kids in non-classroom settings. We are a group of science museums dedicated to bringing science, technology, engineering, and math (STEM) out of the academic cloister and into the wider world. Our organizations are resource hubs for educational programs that involve people of all ages and backgrounds.
Cell (biology) The cell (from Latin cella, meaning "small room") is the basic structural, functional and biological unit of all known living organisms. Cells are the smallest unit of life that can replicate independently, and are often called the "building blocks of life". The study of cells is called cell biology. The cell was discovered by Robert Hooke in 1665. Anatomy There are two types of cells, eukaryotes, which contain a nucleus, and prokaryotes, which do not. Prokaryotic cells A prokaryotic cell has three architectural regions: On the outside, flagella and pili project from the cell's surface. Eukaryotic cells Structure of a typical animal cell Plants, animals, fungi, slime moulds, protozoa, and algae are all eukaryotic. Subcellular components Illustration depicting major structures inside a eukaryotic animal cell Membrane Cytoskeleton A fluorescent image of an endothelial cell. Genetic material Organelles There are several types of organelles in a cell. Eukaryotic
