In order for your body to work properly, your nervous system needs to be working properly. Your nervous system is responsible for helping your brain communicate with your body and helping your body ...

RA can hurt your peripheral nerves, which are part of the peripheral nervous system. That’s the communication system that helps your central nervous system (brain and spinal cord) send and receive ...

The peripheral nervous system comprises all neural structures beyond the brain and spinal cord, including sensory, motor and autonomic fibres that connect the central nervous system to receptors and ...

Obesity affects far more than metabolism and fat storage. It alters immune activity, nerve structure, and tissue organization across multiple organ systems, increasing the risk of diseases including ...

Your peripheral nervous system (PNS) is crucial to navigating daily life. It lets you walk, controls your eye movements, and rings your brain’s alarms when you step on a Lego brick. Yet researchers ...

We’re celebrating 180 years of Scientific American. Explore our legacy of discovery and look ahead to the future. Billions of nerve cells send signals coursing through our bodies, serving as conduits ...

Peripheral neuropathy symptoms often begin with pain or tingling in the hands and feet. Peripheral neuropathy is not common in children. Early diagnosis gives a better chance of reversing nerve damage ...

Peripheral nerve impairments in older adults were tied to a higher risk of subsequent dementia, a study of longitudinal data showed. Combined sensory and motor impairments in the lower leg doubled the ...

Peripheral neuropathy is rarely fatal. However, it can cause serious complications if left untreated. These complications may affect a person’s independence, overall health, and life expectancy.

Atherosclerotic plaques form when lipoproteins and immune cells accumulate on the inner surfaces of arteries. Immune cells in these plaques — such as macrophages, which are part of the innate immune ...

Millions of neurons branch throughout our bodies, keeping them in close communication with our brains. This peripheral network begins to take shape long before birth, as the cells of a growing embryo ...
