Does all body cells exhibit irritability to some extent?
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.
Characteristics of irritability in a muscle tissue?
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.
How do muscle stretch receptors contribute to the body's ability to sense and respond to changes in muscle length during physical activity?
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.
What i s latch bridge mechanism in smooth muscle?
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
What is the first phase after a stimulus in a muscle contraction?
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.
Which muscle characteristic describes the ability of muscle to respond to a stimulus?
Excitability
What is the ability of a muscle to respond to nerve stimulus called?
neuromuscular efficiency neuromuscular efficiency
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.
Is irritability a function of muscle tissue?
Yes. They respond to stimulus.
If a muscle cell receives a second stimulus while it is contracting will it respond to the second stimulus?
no because it doesnt want to
The most distinguishing characteristic of muscle tissue is?
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.
The ability of muscle to receive and respond to stimuli?
excitability
Do bones and muscles work together for movement?
Well, yes but bones have no nerve stimulus so respond to muscle movement.
Does all body cells exhibit irritability to some extent?
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.
How does the threshold stimulus influence muscle 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.
What are the four main special functional abilities of muscle that are the basis for muscle 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).
Stimulus at which the muscle first contracts perceptibly?
Threshold stimulus
