Ch. 1.4 Bio Tools and Technology

1.4 Bio Tools and Tech

Light Microscope: used to magnify specimens; limited magnification









Scanning Electron Microscope: Deflection of electrons used to magnify specimens; provides high magnification and a three-dimensional image












Transmission Electron Microscope: Electrons passing through a specimen used to magnify specimen; provides high magnification and a two-dimensional image










X-rays Imaging: X-rays passing through tissues used to show dense materials (bones, teeth)





Magnetic Resonance Imaging: Magnetic field used to show all tissues, including soft tissues such as tendons and ligaments 





Functional Magnetic Resonance Imaging: Magnetic field that can be used to shown activity in particular brain regions while a subject is performing a task 





Computer Modeling: Use of computers to simulate complex systems when actual experiments are not possible 












Molecular Genetics: Study and manipulation of DNA at the molecular level
