Career Profile
On each side of your head is the auditory system, one of the most beautifully designed organs in the human body. The auditory system not only detects sound, but is closely tied to the vestibular system, which helps a person with balance, and knowing how his or her body is moving through space. Audiologists detect, diagnose, and develop treatment plans for people of all ages who have problems with hearing, balance, or spatial positioning. This important work impacts how well a person is able to… 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

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 first leading cause of death in the United States is heart disease, and the third leading cause is stroke. Cardiovascular technologists or technicians are key members of the healthcare teams that are on the front lines of treating heart and blood vessel diseases and conditions. They set up monitors and tests to help physicians diagnose heart or blood vessel problems. Then they work with physicians to treat an identified problem. For example, they might help break up a blockage in an artery… Read more

Who does a diabetic turn to if they have questions or do not understand how to manage their disease? They consult a certified diabetes educator. These diabetes experts work with people who have diabetes (or pre-diabetes) so they know how to manage their condition. This can include educating people about how to measure and control their blood sugar levels, giving specific diet and exercise recommendations, and providing emotional support. Certified diabetes educators present health… Read more
Career Profile
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

Some patients prefer to treat certain medical problems without the use of medications, surgery, or other traditional therapies. Chiropractors diagnose and treat problems involving the muscles, skeleton, and nervous system using alternative therapies, such as manipulation of the spine and joints, acupuncture, massage, bracing, and heat therapy. They also counsel patients on how to achieve good overall health through diet, exercise, stress management, and rest. They try to treat the patient as a… 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
Career Profile
When a patient gets sick, his or her doctor will take sample cells from the affected part of his or her body and send them to a lab for testing to figure out what is wrong. This is where the cytotechnologist steps in. The cytotechnologist will take the sample cells, make slides from them, and examine the slides under a microscope. Cytotechnologists are trained to detect abnormalities in cells that come from all body sites in order to to make a diagnosis of cancer or other diseases. These… Read more

Good oral hygiene protects not only teeth and gums, but the whole body, reducing the risk of infections, heart disease, clogged arteries, and stroke. Dental hygienists help prevent and correct dental problems by taking X-rays, examining teeth and gums, removing plaque, polishing teeth, injecting local anesthetics, and assisting with dental procedures. They also play a key role in educating patients about how and when to brush and floss. Read more
