A tissue is a part of the body in which cells of the same type work together to perform the same function. Examples of human tissues include epithelial tissue ~ the thin sheets of tissue that line parts of the body such as the intestines and the lungs. Nervous tissue is formed from nerve cells and different types of nervous tissue form the nervous system, the brain, spinal cord and nerves.
Muscular tissue contains specialised muscle cells that can respond to signals from nerves and bring about movement in the body.
The study of how cells work together to form tissues is called histology. Histologists look at cross sections of tissues to see how the individual cells are arranged. They usually use a powerful light microscope to do this as electron microscopes are reserved for studying individual cells and the inside of cells. It is important for trainee doctors to recognise normal histology, and part of a doctor's training involves work at the microscope as well as dissection and anatomy lessons.
