Should a sports injury occur, athletic trainers help to evaluate the injury, determine the treatment needed, and design a fitness regime to rehabilitate the athlete so he or she is ready to go out and compete again.

Shakespeare described humans as a "piece of work," and others have called the body "the most beautiful machine," but like any machine, sometimes body parts need repairs or servicing when the body cannot take care of the problems itself. That's where biomedical engineers come in. They use engineering to solve problems in medicine, such as creating replacement body parts, drug-delivery systems, medical instruments, and test equipment. Their work helps restore health and function, and improves the… Read more

The human body can be viewed as a machine made up of complex processes. Scientists are working on figuring out how these processes work and on sequencing and correlating the sections of the genome that correspond to the individual processes. (The genome is an organism's complete set of genetic material.) In the course of doing so, they generate large amounts of data. So large, in fact, that to make sense of it, the data must be organized into databases and labeled. This is where bioinformatics… Read more

I have black hair, you have blonde hair. I have blue eyes, you have brown eyes. These, and other characteristics, describe what we look like, how tall we are, and even what our personality is, and they are all controlled by our chromosomes. Chromosomes are packages within each of our cells that hold our genes. Our chromosomes also determine if we might inherit any genetic diseases or if birth defects are present. Extracting, testing, and examining the chromosomes from cells is the job of the… Read more

Each time your heart beats, or you breathe, think, dream, smell, see, move, laugh, read, remember, write, or feel something, you are using your nervous system. The nervous system includes your brain, spinal cord, and a huge network of nerves that make electrical connections all over your body. Neurologists are the medical doctors who diagnose and treat problems with the nervous system. They work to restore health to an essential system in the body. Read more

If you are injured in an accident, suffer a stroke, heart attack, or loss of a limb, or are born with conditions that make it difficult to move your body, then you will often be cared for by a physical therapist. Physical therapists review a patient's medical history, test and measure his or her physical condition (things like range of motion, strength, flexibility, balance, coordination, muscle function), and then develop a treatment plan to meet some physical goals. They coach, motivate, and… Read more

Why people take certain actions can often feel like a mystery. Psychologists help solve these mysteries by investigating the physical, cognitive, emotional, or social aspects of human behavior and the human mind. Some psychologists also apply these findings in order to design better products or to help people change their behaviors. Read more

Pain is something that no one enjoys or wants to remember, especially during surgery. Certified registered nurse anesthetists, who share virtually identical responsibilities with anesthesiologist assistants, are key members of anesthesia healthcare teams. Working independently, or under the supervision of an anesthesiologist (a medical doctor), they prepare patients for anesthesia, administer anesthesia, monitor patients closely during surgery, and monitor patients' progress after surgery. They… Read more

Do you like a good mystery? Well, an epidemiologist's job is all about solving mysteries—medical mysteries—but instead of figuring out "who done it" like a police detective would, they figure out "what caused it." They find relationships between a medical condition and things like human behavior, environmental toxins, genes, medical treatments, other diseases, and geographical location. For example, they ask questions like what causes multiple sclerosis? How can we prevent brain… Read more
