The nervous system of the human body has been extensively mapped. Anatomical drawings are available to demonstrate the pathways traced by nerves as they move through the body and to highlight the different kinds of nerves present in the body. This information is studied in detail by physicians d...
Nerves in a human body work by sending small electrical impulses from cell to cell. These impulses originate in onenerve celland travel down a long axon, which is protected by amyelin sheath. As electrical impulses reach the end of the axon, they are detected by the dendrites of the next ...
direct contact with this sore. Later there may be a rash on the soles, palms, or other parts of the body (seen here), as well as swollen glands, fever, hair loss, or fatigue. In the late stage, symptoms come from damage to organs such as the heart, brain, liver, nerves, and ...
The winners of Nikon’s annual Small World photography contest reveal tiny marvels of the natural world that are normally hidden from sight.
Born of a need for detailed and medically accurate 3D anatomical resources, Primal created our model from CT scans of a full human skeleton. Structures such as muscles, vessels, nerves and organs were constructed using our own MRI data and cross-sectional cadaver images from the Visible Human ...
The atlas also provides essential information and quizzes involving identification and function of muscles, nerves, ligaments and bones. Art, anatomy and imaging technology are brought together to allow for a better understanding of normal function and we anticipate that the atlas may also help...

Nerve tissue is used to control the human body. There are three primary components of this tissue group: the brain, nerves, and spinal cord. These three components work together because the nerves can generate and conduct electrical signals. The spinal cord acts as a route for the nerves to...
Compressed nerves cause a wide range of symptoms depending on where they are located in the body. In some cases, a compressed nerve can be very painful, while other times it may only cause numbness and tingling. There is typically more pain when a major nerve becomes compressed, such as th...
Cryotherapy is used to treat abnormal skin cells, prostate cancer, pinched nerves, neuralgia, neuromas, and more. Hemorrhoids Hemorrhoids (piles) are swollen veins in the rectum and anus. Causes include pregnancy, obesity, diarrhea, a low-fiber diet, and prolonged sitting on the toilet. ...
