e. recruitment (multiple motor unit summation) - MMUR is a process observed at the level of an entire muscle; it is the main means of increasing tension production, by stimulating a greater proportion of the individual motor units to contract simultaneously.

Motor unit summation or spatial summation is the recruitment of additional motor units within a muscle to develop more force. Motor unit summation occurs until sufficient force is developed within ...

Explain the difference between temporal/wave summation and motor unit summation Wave summation increases the frequency of contractions to produce greater force while motor unit summation uses increased motor unit recruitment.

en.wikipedia.org/wiki/Summation_(neurophysiology)

Summation, which includes both spatial and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).

Motor unit summation is the build-up of the myoelectrical signals of the active motor unit during continuous, sustained muscle contraction. Sustained contraction causes the motor unit to fire continuously, creating myoelectrical signal fusion that produces larger forces than a single contraction.

Wave summation releases more calcium and increases the force of contraction by increasing the firing rate of motor neurons (The second contraction takes place before the first is completely at ...

Multiple Motor Unit Summation in the Body • We need to recruit fewer motor units to move a light object compared to a heavy object. ** Start the animation by clicking on the weight bar that says "80", then place the slider bar on few.

Muscle contraction is also influenced by motor unit summation. The motor unit consists of a neuron and every muscle fiber connected to it. A nerve impulse moving through the axon of a neuron causes every muscle cell attached to the motor unit to contract. In motor unit summation, stronger contractions are achieved by stimulating large motor ...

multiple impulses from several neurons at the same time) and temporal (i.e., several impulses from one neuron over time) summation of all inputs at a given moment. In addition, the summation of excitatory and inhibitory influences will modulate the outcome. Synapses that are located closer to

Temporal summation can be illustrated by firing action potentials in a presynaptic neuron and monitoring the resultant EPSPs. For example, in Figs. 16.14A and 16.14B, a single action potential in sensory neuron 1 produces a 1-mV EPSP in the motor neuron.Two action potentials in quick succession produce two EPSPs, but note that the second EPSP occurs during the falling phase of the first, and ...
