ST - In regards to excitable cell (i.e. neurons) the minimum mV need to trigger a AP (action potential) and is around -40mV (although this may vary depending on the cell).
In additional to this; excitable cells (i.e. neurons) shows an all-or-nothing property, such that if the stimulus threshold is not met the action potential will not be created.
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.
Any stimulus below the neuron's threshold potential will not result in a response, as it is not strong enough to generate an action potential. Neurons require a minimum level of stimulus intensity to reach the threshold potential and fire an action potential.
The smallest intensity of a stimulus that you can detect 50 percent of the time is called the absolute threshold. This threshold varies depending on the sensory system and the specific stimulus being measured.
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
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.
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.

it is known as the threshold stimulus usually seen in tonic contraction

Threshold
Yes, a stimulus needs to reach a certain threshold level of strength in order to generate a nerve impulse. This threshold is required to depolarize the cell membrane and initiate the action potential. If the stimulus is not strong enough to reach this threshold, no nerve impulse will be generated.
absolute threshold is the lowest level that a person will feel sensation differential threshold is the minimal difference that a person can detect between two similar stimuli For example a change in volume in certain frequencies would be crossing the absolute threshold, how much that change would need to be for someone to detect it would be dealing with the difference threshold.
The threshold stimulus is the stimulus required to create an action potential. So any stimulus under this level will not cause muscle contraction, while a stimulus above this level will cause the muscle to contract. The higher the stimulus the more muscle fibers are recruited, and thus the higher the response.
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.
