High threshold motor unit definition
Webmotor neuron. This branch (telodendron) forms a neuromuscular junction (NMJ) with the muscle cell membrane (sarcolemma), Impulses arriving on the nerve fiber are transmitted to the sarcolemma and ultimately cause the contraction of the muscle fiber. A muscle fiber is a multinucleated cell whose sarcoplasm WebJan 1, 2004 · Fundamentally, the motor unit is a transducer that converts neural signals received by the motor neuron into mechanical outputs by the muscle unit. Within this framework, the motor unit consists of a controller (the motor neuron) that adjusts the output level of the motor (the muscle unit).
