Define threshold stimulus anatomy
WebThere is a wide range of motor units within many skeletal muscles, which gives the nervous system a wide range of control over the muscle. The small motor units in the muscle will have smaller, lower-threshold motor neurons that are more excitable, firing first to their skeletal muscle fibers, which also tend to be the smallest. WebThis means that the interior of the cell is negatively charged relative to the outside. See videos: Neuron resting potential description, Neuron resting potential mechanism. Hyperpolarization is when the membrane potential becomes more negative at a particular spot …
