Excitibilty
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.
Irritability in muscle tissue refers to its ability to respond to stimuli by generating an action potential. This leads to muscle contraction, allowing for movement. Irritability is a key characteristic of muscle tissue that enables it to function in response to various signals from the nervous system.
Muscle stretch receptors are sensory receptors located in muscles that detect changes in muscle length. When a muscle is stretched during physical activity, these receptors send signals to the brain, which helps the body sense and respond to the changes in muscle length. This information is important for maintaining balance, coordination, and muscle control during movement.
smooth muscles have the ability to sustain the prolong contraction with a little use of energy.this latching of energy in smooth muscles is called latch phenomena,smooth muscles have ability to reduce strength of stimulus once they have fully contracted
The first phase after a stimulus in a muscle contraction is excitation-contraction coupling. This involves the transmission of the action potential along the sarcolemma and the release of calcium ions from the sarcoplasmic reticulum.

neuromuscular efficiency neuromuscular efficiency
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
Well, yes but bones have no nerve stimulus so respond to muscle movement.
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.
Muscle tissue has four main properties: Excitability (ability to respond to stimuli) Contractibility (ability to contract) Extensibility (ability to be stretched without tearing) Elasticity (ability to return to its normal shape).
