WebMay 18, 2007 · The first is the mean threshold m k, which is the stimulus at which a motor unit has a 50% probability of firing and determines the horizontal location of the excitability curves that are shown in Figs 2(c) or 2(d). In setting a prior for m we require one that gives economical values for the number of units, N. WebAs the action potential travels down the axon, positive ions continue to flood the cell. Eventually, this influx reaches the very end of the neuron – the axon terminal. When this happens, the positive ions trigger voltage-gated calcium channels to open and let calcium ions …

WebCommunication occurs between nerves and muscles through neurotransmitters. Neuron action potentials cause the release of neurotransmitters from the synaptic terminal into the synaptic cleft, where they can then diffuse across the synaptic cleft and bind to a receptor molecule on the motor end plate. WebA single axon can have multiple branches, allowing it to make synapses on various postsynaptic cells. Similarly, a single neuron can receive thousands of synaptic inputs …
