Web1. If there is only one action potential in the nerve that excites the muscle, then the muscle will contract only once. This is called a twitch. It is the minimum contraction for the whole muscle. 2. Notice that the duration of the contraction, the twitch, is much longer than the duration of the action potential. 3. WebWave (temporal) summation occurs if consecutive stimuli are applied during the relaxation period of each preceding muscle contraction (refer to Figure 1c). In this case, each …

Temporal vs Spatial Summation - A Brief Overview

Web19 Oct 2009 · Summation is the finite sum of multiple, fixed values. Integration is the limit of a summation as the number of elements approches infinity while a part of their respective value approaches zero. WebWith that understanding, let’s look at the 2 types of summation: 1. Temporal summation. 2. Spatial summation. I’m going to do a drawing to illustrate both. With temporal summation, what we have is a pre-synaptic neuron, so let’s just draw an axon, and I’m going to simplify it by making just 1 axon terminal, and that makes a synapse with ...
