Your muscles move when nerve signals from the brain tell them to get to work. Electromyography (EMG), a diagnostic test, measures how well your muscles respond to those signals. Movement is a complex ...

Neurophysiology is a discipline within the health sciences that deals with the measurement and assessment of nervous system function, rather than the anatomy of the nervous system. This field helps to ...

A nerve conduction velocity test measures the speed of electrical impulses passing through the nerves of the body. In this article, learn about how a nerve conduction velocity or NCV test is used, ...

Researchers have achieved patch-clamp studies of an elusive part of mammalian myelinated nerves called the Nodes of Ranvier. At the nodes, they found unexpected potassium channels that give the ...

Researchers have discovered that glial cells - one of the main components of the brain -not only control the speed of nerve conduction, but also influence the precision of signal transduction in the ...

MEMBRANES are a ubiquitous cell component responsible for controlling many vital cellular functions, including selective permeability, ion accumulation and conduction of nerve impulses. It is widely ...

Dr. Justin Grant, DO, a fellowship-trained sports medicine provider at Colorado Advanced Orthopedics (CAO), is certified in nerve conduction study (NCS) and needle electromyography (EMG). NCS ...

The nerve cell is made up of a cell body and a long, projecting nerve fiber called the axon that is responsible for the transmission of electrical impulses from the cell body to receiving neurons, ...

How does our nervous system operate so quickly and efficiently? The answer lies in a membranous structure called myelin. Aa Aa Aa All our activities — eating, walking, talking — are controlled by our ...
