MIT scientists find that motor neuron growth increased significantly over 5 days in response to biochemical (left) and mechanical (right) signals related to exercise. The green ball represents cluster ...

The hypoglossal nerve is one of the 12 cranial nerves arising from the brain. It's a paired nerve, and you have two — left and right. Together, the two hypoglossal nerves control the muscles of the ...

Regular activity not only strengthens muscles but can bolster our bones, blood vessels, and immune system. MIT engineers have now found that exercise can also have benefits at the level of individual ...

Occasional leg cramps are considered common and usually harmless, especially after physical exertion, dehydration, or prolonged sitting or standing.

Exercise can have benefits at the level of neurons, through chemical and mechanical effects, researchers find. The discovery could inform exercise-related therapies for repairing damaged and ...
