A and P Muscle Lab

Lab Quiz

A larger number of neurons sending signals at the same time is called... Spatial summation
The result of a spatial summation is... A quick and powerful contraction of several motor units
A few neurons sending a high rate of signals to the same group of muscle cells is called... Temporal summation
Temporal summations... are weaker then spatial but last longer. It involves less electrical activity then spatial.
As the frequency of a stimulus increases (more signals from a neuron)... A particular set of muscle fibers well become tired and eventually become tetanus (locked)
Motor Unit a single α-motor neuron and all of the corresponding muscle fibers it innervates;
Threshold Stimulus The weakest stimulus capable of producing an action potential in an excitable cell.
Temporal (or wave) summation Temporal Summation occurs when the time constant is sufficiently long and the frequency of rises in potential are high enough that a rise in potential begins before a previous one ends.
Spatial Summation Spatial summation is the algebraic summation of potentials from different areas of input, usually on the dendrites.
Tetanus a sustained muscular contraction resulting from a rapid series of nerve impulses

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
