The minimum stimulus needed to cause a contraction is called the threshold stimulus. This is the minimal level of stimulation required to activate muscle fibers and initiate a contraction response.

What is needed besides calcium for contraction to occur?
In addition to calcium, muscle contraction requires adenosine triphosphate (ATP) to provide energy for the process. ATP is needed to fuel the movement of myosin heads along actin filaments during the contraction.
Why is calcium needed for muscle contraction?
Calcium is essential for muscle contraction because it binds to a protein called troponin, which triggers a series of reactions that allow the actin and myosin filaments in muscle cells to interact and produce force. Without sufficient calcium, the muscle cells cannot contract effectively.
A quantity of merchandise or materials over the minimum needed reduce the risk of running short is called?
The quantity of merchandise or materials over the minimum needed to reduce the risk of running short is called a safety stock. It acts as a buffer to ensure that there are enough materials or products available to meet demand in case of unexpected fluctuations or delays in the supply chain. Maintaining a safety stock helps to prevent stockouts and disruptions in production or customer service.
What is needed to accomplish a strong contraction and are stimulated at a rapid rate?
To accomplish a strong contraction that is stimulated at a rapid rate, the muscle fibers need sufficient ATP for energy production, calcium ions for muscle contraction, and acetylcholine for nerve stimulation. Additionally, a well-coordinated activation of motor units is necessary to achieve a strong and rapid contraction.
Do negative feedback mechanisms decrease or end the original stimulus?
Negative feedback mechanisms work to decrease or counteract the original stimulus, rather than completely ending it. The goal is to bring the system back to its set point or normal level by regulating the stimulus within a certain range.
What is the minimal stimulus needed to elicit a muscle contraction is called?
Threshold Stimulation
The minimal strength of stimulation needed to elicit a muscle contraction is called the threshold stimulus?
true
What is a graded muscle response?
It is the variation of stimulation needed in skeletal muscle contraction in order to have controlled movement.
A muscle fiber will not respond to a stimulus until that stimulus reaches what?
A muscle fiber will not respond to a stimulus until that stimulus reaches the threshold level needed to trigger an action potential. This threshold level is the minimum amount of stimulus required to elicit a response from the muscle fiber.
What is the minimal strengh of stimulation needed to elicit a muscle fiber contraction called?
Threshold
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
The minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
What is perceptual threshold?
Perceptual threshold refers to the minimum level of stimulus needed for a person to detect a particular stimulus. It is the point at which the stimulus becomes strong enough to be recognized by an individual's senses.
What is the minimum income needed to support a household called?
the standard of living
What is the Point at which a person can detect a stimulus 50 percent of time it is presented?
The point at which a person can detect a stimulus 50% of the time it is presented is known as the absolute threshold. This threshold represents the minimum intensity of a stimulus needed to detect it half of the time. It is often used in psychology to study perception and sensory processing.
Minimum level of stimulation required to trigger a neural impulse?
The minimum level of stimulation required to trigger a neural impulse is known as the "threshold." This threshold is the minimum amount of neurotransmitter release or electrical stimulation needed to generate an action potential in a neuron. Below this threshold, the neuron will not fire an action potential.
What is the minimum amount of overload needed to achieve physical fitness called?
yeah
What is the minimum amount of unstable atoms needed to produce an uncontrolled chain reaction is called?
Critical mass is the minimum amount of unstable atoms needed to sustain a chain reaction in a nuclear reaction.
