Excitability
Muscle excitability is the ability to respond to a stimulus, such as a nerve signal or hormone, by generating an electrical impulse that leads to muscle contraction. This trait allows muscles to react to signals from the nervous or endocrine systems to produce movement.
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.
Yes. They respond to stimulus.
no because it doesnt want to
Excitability = the ability to receive and respond to a stimulus Contractility = the ability to shorten Extensibility = the ability to be stretched Elasticity = the ability to resume normal length after contraction or having been stretched.
excitability
It is called muscle fatigue.
Well, yes but bones have no nerve stimulus so respond to muscle movement.
Threshold Stimulation
Muscle cells are irritable and respond to stimuli. Muscle twitch is defined as contraction and relaxation in the muscle cell. The stimulus needs to be above a certain threshold for the muscle fibres to react. The more the stimulus, the greater the strength of the contraction.
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.
