This process is called long-term potentiation. Long-term potentiation operates at the synapse, using the neurotransmitter glutamate and the receptor known as the NMDA receptor.
Web2 days ago · In theory, force summation occurs when all body parts act simultaneously In practice, the strongest and lowest body parts around the centre of gravity (e.g. trunk and thighs) move first, followed by the weaker, lighter, and faster extremities.

WebThe integration of postsynaptic potentials that occur in the same place—but at slightly different times—is called temporal summation. For instance, let’s suppose that excitatory … 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.
