A description of the nervous system

Aug 09,  · The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body. The nervous system transmits signals between the brain and the rest of the body, including internal organs.

In addition to the traditional X-ray, a specialized X-ray called a fluoroscopy examines the body in motion, such as blood flowing through arteries, according to the NIH.

Positron emission tomography PET is a procedure that descriptions cell or tissue metabolism and brain activity to detect tumors or diseased tissue or tumors, the NIH noted. A spinal tap places a needle into the spinal canal to drain a small amount of cerebral spinal fluid that is tested for infection or other abnormalities, according to the NIH.

Diseases of the nervous system "Of all the diseases of the nervous system, the most common difficulty that people have is pain, Activism aids anger essay love politics much of that is nerve-related," nervous to Dr. The Clinic also noted that the nervous system can also be affected by vascular disorders such as: Treatments vary from anti-inflammatory medications and pain medications such as opiates, to implanted nerve stimulators and wearable devices, Gozani said.

In fact, most body parts are far more complicated than that, while some seem to have no business being inside there at all.

What is the Nervous System?

Bundles of axons, called nerves, are found throughout the body. Axons and dendrites allow neurons to communicate, even across long distances. Different types of neurons control or perform different activities. For instance, motor neurons transmit messages from the brain to the muscles to generate movement. Sensory neurons detect light, sound, odor, taste, pressure, and heat and send messages about those things to the brain.

The rate of breathing, blood pressure, and heart rate are also modulated by the nervous system.
