Yes, norepinephrine can facilitate the reaching of threshold more quickly in neurons. By increasing the excitability of neurons, norepinephrine enhances the likelihood of action potentials being generated, which can lead to faster transmission of signals. This effect is particularly notable in areas of the brain involved in attention and arousal, where norepinephrine plays a crucial role in modulating neuronal activity.

What is threshold principle?
The threshold principle is a concept in various fields, including economics and environmental science, that refers to the idea that a certain level or threshold must be crossed before a significant effect or response occurs. For example, in environmental contexts, it suggests that pollutants may not cause harm until they exceed a specific concentration. This principle can help in decision-making by identifying critical points where intervention is necessary to prevent adverse outcomes. Overall, it emphasizes the importance of understanding the limits within which systems operate effectively.
Does the desert cause an effect on the bread became stale?
the word 'because' gives you the clue....it tells you the effect is made because...of an event!!
What is the most common cause of death in the desert?
Dehydration and/or starvationAnother Answer:The most common cause of death in deserts is by drowning. More people drown in the desert every year than by any other cause. Flash floods can quickly develop after sudden thunderstorms and can rapidly fill arroyos and streams to overflowing. People have little to no warning and can be quickly swept away and drowned by these sudden floods. Other folks are drowned when they attempt to walk or drive across a flooded roadway.
WHAT IS SHALLOW BREATHING INDICATIVE OF?
Shallow breathing can be indicative of pneumonia, asthma, or a lack of oxygen. If the body does not receive sufficient air, it will quickly shut down and cause death.
What hormones would cause your heart to beat faster?
norepinephrine

The minimum stimulus needed to cause a contraction is called the?
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 the minimal level of stimulus to cause a muscle contraction?
it is known as the threshold stimulus usually seen in tonic contraction
Can Concerta cause impotence?
absolutely. it increases norepinephrine, which has all sorts of negative effects down there.
Drivers become subject to the liability insurance law when accident damages amount to how much?
Drivers become subject to the liability insurance law when accident damages amount to a state-specific threshold, commonly set at around $500. This means that drivers must carry liability insurance coverage to pay for damages they cause in an accident, once the threshold is reached.
Is norepinephrine cause bronchial relaxation?
No, norepinephrine typically causes bronchial constriction rather than relaxation. It is a neurotransmitter and hormone that activates adrenergic receptors in the body, leading to increased heart rate, blood pressure, and bronchodilation.
What is the minimal impulse that can initiate a muscle contraction?
Threshold stimulusThe minimal level of stimulation required to cause a fiber to contract is called the THRESHOLD STILULUS.
What can cause mold to spread quickly?
1. moisture 2. moderate temperatures (ie. +4ºC to room temperature) 3. air circulation (only once mold has reached sufficient mass)
The two neurotransmitters that affect smooth muscle cells are acetylcholine and?
norepinephrine. Acetylcholine mainly causes smooth muscle contraction, while norepinephrine can either cause contraction or relaxation depending on the type of receptor it binds to on the smooth muscle cell.
Why would a person be taking norepinephrine?
Norepinephrine causes peripheral blood vessels to narrow while making coronary arteries dilate. It also increases the strength of heart beats. It can be used in cases of dangerously low blood pressure, such as during a myocardial infarction. Of course, excessive amounts of norepinephrine can cause hypertension and other problems, so it should only be taken while appropriately supervised.
Does norepinephrine cause a decrease in stroke volume?
Norepinephrine primarily acts as a vasoconstrictor and can increase heart contractility, which typically leads to an increase in cardiac output. However, in certain situations, such as when there is excessive vasoconstriction or under conditions of high vascular resistance, it may indirectly contribute to a decrease in stroke volume by reducing venous return. Overall, the effect of norepinephrine on stroke volume can vary depending on the physiological context.
