Question
Neuronal AP 1H Muscle AP Contraction force 1. Look at event "A" What does this time between the action potential in the skeletal muscle to the actual twitch 2. What is going on here? aiium movts out OF St to pnd to ronin to 3. Could the neuron "fire" again and stimulate the skeletal muscle again? That is to say, have both the neuron and skeletal muscle fiber exited out of absolute refractory period so they could be excited again? Now look at "B"- this is showing you repeated action potentials of a neuron resulting in repeated action potentials within the skeletal musclefibers. Notice that the AP's are coming in such quick succession the muscle fibers are not allowed to completely relax. 4. If we assume all motor units have been recruited, what type of summation is occurring here? Now look at "C" this is showing you MANY repeated action potentials of a neuron resulting in repeated action potentials within the skeletal muscle fibers. Notice that the AP's are coming in such quick succession the muscle fibers are not allowed to relax AT ALL . What type of summation is occurring here? 6. What is the plateau part of the contraction force graph called? Can a muscle "hold" this phase indefinitely? Why? What would happen to the force of contraction if both recruitment and temporal summation occurred? 7.Explanation / Answer
1. Latent period
Explanation: Latent period is the time during which the muscle does not contract.
Contraction in muscle as a result of one action potential is termed a twitch. Latent period represents the time between the application of stimulus and the beginning of the contraction cycle of the muscle.
