Motor neurons are nerve cells that control our muscles by sending signals from the brain and spinal cord out to the body. In ...

1. The motor neuron pools targeting the synergistic or antagonistic muscles are distributed in the closer spinal cord segments. For example, the motor neuron pools targeting the extensor carpi ulnaris ...

Whenever a motor unit is active, the motor neuron releases acetylcholine into the neuromuscular junction and all of the muscle fibers controlled by that motor neuron contract. Muscle twitches occur ...

When cross-sections of lateral gastrocnemius muscle fibers, outlined by staining with anti-dystrophin antibody, were measured for fiber area at the same level of the muscle in mutant and wild type ...

Unipolar neurons: These neurons have a single long axon that is responsible for sending electrical signals.The axon in unipolar neurons is myelinated, which allows for rapid signal transmission.

Motor neuron disease (MND) is a devastating condition that causes progressive muscle weakness by damaging the motor neurons, ...

Cedars-Sinai has created a lifelike model of the mysterious and fatal disease that could help identify a cause of the illness as well as effective treatments.

These diseases lead to the degeneration and eventual death of motor neurons, resulting in muscle weakness, wasting, and difficulties with speech, swallowing, and breathing. The most well-known ...

Wrist-based accelerometry may be a feasible method for continuous monitoring for individuals with motor neuron disease, according to data published in eBioMedicine.“Actigraphy, which leverages ...

Muscle fiber types affect cognitive abilities differently Fast-twitch muscle fibers, which are activated during high-intensity exercise, produce different myokines and growth factors than slow ...

Multifocal motor neuropathy (MMN) is a rare disease that causes slowly worsening muscle weakness, mainly in your hands, arms, and legs. It affects your body's motor nerves, which control your muscles.

Mitochondrial abnormalities, or problems in cells' powerhouses, contribute to nerve cell death linked to motor control in MS, ...
