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.

Feliz [49]

The given diagram is food chain. Food chain is a sequence of populations or organisms of an ecosystem through which the food and its contained energy passes with each member becoming the food of a later membre of the sequence. The number of trophic levels in a food chain is 3-6 and in each trophic level a lot of biomass is consumed in liberating energy.

In the above food chain plants( producers) radiant light energy into chemical form. Rodents are primary consumer, owl is a secondary consumers or primary carnivores and wolf is a tertiary consumer or secondary carnivores.

Triggering of the muscle action potential occurs after
vekshin1

Triggering of the muscle action potential occurs after Ach binds to chemically gated channels in the motor end plate membrane. Acetylcholine (Ach) is a neurotransmitter produced by nerve cells.

An action potential is an electrical signal that travels along the cell membrane as a wave.

This action potential (muscle action potential) drives the contraction of muscle fibers.

When the action potential reaches the neuromuscular junction (i.e., the motor end-plate), acetylcholine (Ach) is released into the synaptic cleft.

Subsequently, Ach can bind and open specific channels localized on the surface of the muscle cells, thereby depolarizing them and triggering muscle contraction.
