In vertebrates, motor neurons (also called motoneurons) are efferent neurons that originate in the spinal cord and synapse with muscle fibers to facilitate muscle contraction and with muscle ...

The muscle unit comprises the muscle fibers innervated by a single motor neuron and corresponds to the peripheral element of the motor unit. The combinations of motor unit recruitment and rate coding ...

These units include a phrenic motor neuron located in the cervical spinal cord and the group of diaphragm muscle fibers it innervates as the essential elements of neural control. Thus, as a phrenic ...

They happen when the muscle’s motor neuron—or messaging system responsible for moving a particular group of muscle fibers—randomly fires. The tips of motor neurons can be sensitive ...

Motor neurons project from the central nervous system to innervate muscle cells to either directly or indirectly control their activity. Contact between a motor neuron and muscle cell is usually ...

The scientists explained that motor units are composed of a single motor neuron and the muscle fibers that it can excite. Various motor units, activated in different combinations and sequences ...

Objective Progressive muscular atrophy (PMA) is a clinical diagnosis characterised by progressive lower motor neuron (LMN) symptoms/signs with ... on myalgia and slight lymphatic infiltration on a ...

2 Hyperexcitability leads to fasciculations and muscle cramps, and potentially enhances motor neuron death, via glutamate-induced excitotoxicity and increased oxidative stress and metabolic demand. In ...
