Motor Unit Remodeling Aging
Motor Unit Remodeling Aging
Motor unit remodeling aging refers to age-related reorganization of motor units consisting of a motor neuron and its innervated muscle fibers. Aging leads to loss of motor neurons, followed by compensatory reinnervation of orphaned muscle fibers by surviving neurons. This process results in fewer but larger motor units. While initially adaptive, motor unit remodeling reduces fine motor control and increases fatigability. Remodeling also alters muscle fiber composition, favoring slower, less powerful contractions. Motor unit remodeling aging contributes to reduced strength, coordination, and functional capacity. Understanding this process highlights how neural adaptation influences muscle aging and movement control.
