The formation of the neuromuscular junction (NMJ) is directed by reciprocal interactions between motor neurons and muscle fibers. Neuregulin (NRG) and Agrin from motor nerve terminals are both ...

Scattered throughout skeletal muscle, the muscle spindles are composed of connective tissue capsules containing bundles of specialized muscle fibers called intrafusal fibers. Wrapped around the middle ...

During restricted periods of development (embryonic day (E) 14.5-E15.5 in mice 1), peripheral innervation of a subset of type I myotubes by group Ia sensory (but not motor 9) axons provides ...

We all learned in high school biology that mitochondria are the powerhouse of the cell. But powering up those cellular engines requires a molecular spark. Now, scientists at the Salk Institute have ...

Muscles and nerve fibers allow a person to move their body and enable the internal organs to function. There are more than 600 muscles in the human body. People also have different types of muscle. A ...

Researchers confirm and explore the role of estrogen-related receptors in regulating energy production in muscle cells during exercise. The findings indicate that developing a drug to boost ...
