One of the mysteries of the English language finally explained.
A nerve cell forming part of a pathway along which impulses pass from the brain or spinal cord to a muscle or gland.
- ‘Muscles are wired to the brain by nerve cells called motor neurons, which are like wires biochemically soldered to the outside of a muscle fibre.’
- ‘After years of trial and error, scientists have coaxed human embryonic stem cells to become spinal motor neurons, critical nervous system pathways that relay messages from the brain to the rest of the body.’
- ‘Muscles are stimulated by signals from nerve cells called motor neurons.’
- ‘By turning these stem cells into motor neurons they will have a unique opportunity to discover what cause these cells to degenerate.’
- ‘Paralysis is typically due to damage to the spinal cord or to the motor neurons that control muscles.’
- ‘As motor neurons are destroyed, muscles weaken and lose their ability to move.’
- ‘Segmental hypotonias are associated with disorders of the motor neuron, peripheral nerve, neuromuscular junction and skeletal muscle.’
- ‘Muscles move in response to impulses from nearby motor neurons.’
- ‘The loss of these motor neurons causes the muscles under their control to weaken and waste away, leading to paralysis.’
- ‘University of Wisconsin-Madison researchers have turned human embryonic stem cells into spinal motor neurons.’
- ‘The polio virus damages 95% of brain stem and spinal cord motor neurons, killing on average at least half of them.’
- ‘Respiratory muscle weakness may result from involvement of the descending respiratory pathways, lower respiratory motor neurons, and anterior roots.’
- ‘The illness destroys motor neurons in the brain and spinal cord, gradually robbing victims of their ability to move - and ultimately to swallow or breathe.’
- ‘Kandel focused on a simple circuit where a sensory neuron conveying information about touch connects directly to a motor neuron that activates a muscle.’
- ‘Transforming embryonic stem cells into motor neurons had eluded researchers for decades, until now.’
- ‘They injected these regenerated motor neurons into the spinal cord of a chick, and the neurons grew out and connected up to the rib muscles.’
