saveliy_v [14]

When an external stimulus crosses the threshold, a muscle fibre will respond.

<h3>The level of the threshold</h3>
  • For the identification of the electrical activity carried out by the active muscles, the threshold level is a crucial consideration.
  • A portion of the electrical activity carried out by the target muscles may be excluded if the chosen threshold level is higher than the overall activity.
<h3>What is the stimulus threshold for muscle contraction?</h3>
  • A certain stimulus magnitude is necessary for muscle contraction.
  • The threshold stimulus is the smallest amount of force needed for a stimulus to cause a muscle to contract in response.
  • If the stimulus intensity is less than this threshold value, there is no response.

In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used
Veseljchak [2.6K]

Answer:

The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.

SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.
