Brain Atlas - Introduction The central nervous system (CNS) consists of the brain and the spinal cord, immersed in the cerebrospinal fluid (CSF). Weighing about 3 pounds (1.4 kilograms), the brain consists of three main structures: the cerebrum, the cerebellum and the brainstem. Cerebrum - divided into two hemispheres (left and right), each consists of four lobes (frontal, parietal, occipital and temporal). The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. – closely packed neuron cell bodies form the grey matter of the brain. Cerebellum – responsible for psychomotor function, the cerebellum co-ordinates sensory input from the inner ear and the muscles to provide accurate control of position and movement. Brainstem – found at the base of the brain, it forms the link between the cerebral cortex, white matter and the spinal cord. Other important areas in the brain include the basal ganglia, thalamus, hypothalamus, ventricles, limbic system, and the reticular activating system. Neurons
Student Nurse - A&P Anatomy and Sectional Terminology It sounds silly, but you learn as many new words in an A&P course as you do a beginning foreign language course. Really --there's been research to prove it! - Kevin Patton Links here are for general A & P resources. Twins Every summer, on the first weekend in August, thousands of twins converge on Twinsburg, Ohio, a small town southeast of Cleveland named by identical twin brothers nearly two centuries ago. They come, two by two, for the Twins Days Festival, a three-day marathon of picnics, talent shows, and look-alike contests that has grown into one of the world's largest gatherings of twins. Dave and Don Wolf of Fenton, Michigan, have been coming to the festival for years. "Must be a twins thing," Don says. This afternoon at the festival the brothers have stopped by a research tent sponsored by the FBI, the University of Notre Dame, and West Virginia University. "Although identical twins may look the same to you and me, a digital imaging system can spot minute differences in freckles, skin pores, or the curve of their eyebrows," says Patrick Flynn, a computer scientist from Notre Dame. Because their beards cover half of their faces, the Wolf brothers pose a particular challenge. "I don't hate it.
Master Muscle List Home Page Complete Genomics May Be Worth The Gamble I have been following Complete Genomics (GNOM) for a while now. I've even put it in my list of five favorite stocks. I really like its products; I really like its services, and I really like its CEO, Cliff Reid. By all accounts this is a great little company ready to take off like a rocket. Complete Genomics is an early stage biotech company engaged in human DNA sequencing using proprietary machines, process, and analytics. Sequenom (SQNM) and Amarin (AMRN) are two examples of a developmental stage biotechs that missed their quarterly targets but didn't see their stock price take a dive next day.

Anatomy and Physiology animations Listed below are a collection of physiology animations and anatomy animations. These animations are intended to support text or lecture and it is important that they are not seen as stand-alone reference material. Notes: If you or your students discover any factual errors in the animations please let me know: andrew@visualization.org.uk Some of the animations can only be accessed from the university network - please contact Liz Hodgson in the LDU if you would like them on WebCT so that students can access them externally. Visual detail in Flash animations can often be magnified (click on the animation with the right mouse button and use the zoom control) Here are some animations of organs/organ systems: Cranial nerves (No text version) Cranial nerves (Customised version)) Anatomical directions and sections. Central and Peripheral Nervous System Vertebrae: meninges etc. Brain: meninges cerebrospinal fluid etc. Primary motor and somatosensory Cortices (Homunculus) Skin turgor Stomach, liver etc.
Molecular pathology - Human Molecular Genetics - NCBI Bookshelf Anatomy and Physiology Learning Modules - CEHD - U of M Quiz Bowl and Timed Test were retired at the end of summer 2013. Quiz Bowl had always been buggy, as many people had pointed out, and it had become difficult to maintain. It also used technology that doesn’t work on a lot of newer computers or tablets. Timed test depended on a browser add-on that both Microsoft and Apple have encouraged users to remove for security concerns. For these reasons, we took these two quizzes down at the end of the month.

"Junk DNA" Allowed Us to Survive as a Species Highly infectious viral diseases -including the Plague, yellow fever, measles, smallpox and he Spanish Flu, which killed 50 million people at the end of the First World War, moving from one cell to the next, transforming each new host into a factory that makes even more virus. In this way, one infected cell soon becomes billion -that die when the host dies. Endogenous retroviruses, however, once they infect the DNA of a species they become part of that species: they reside within each of us, carrying a record that goes back millions of years. These viral fragments are fossils that reside within each of us, carrying a record that goes back millions of years. That is until Thierry Heidmann who runs the laboratory at the Institut Gustave Roussy, on the southern edge of Paris, brought one to life. After resurrecting the virus, the team placed it in human cells and found that their creation did indeed insert itself into the DNA of those cells. Posted by Casey Kazan.
