A muscle fiber will not respond to a stimulus until that stimulus reaches what?
it will not respond until it reaches the threshold level
Which muscle characteristic describes the ability of muscle to respond to a stimulus?
Excitability
Is irritability a function of muscle tissue?
Yes. They respond to stimulus.
Which muscle trait is the ability to respond to a stimulus such as a nerve or hormone?
Excitibilty
What is the ability of a muscle to respond to nerve stimulus called?
neuromuscular efficiency neuromuscular efficiency
How does the frequency of stimulation affect the amount of force generated by the muscle?
Increasing the stimulus to an isolated muscle increases the strength of a contraction. A muscle begins to contract when the stimulus is given; however, if the muscle does not finish contracting before the next stimulus hits, then the force of the contraction will increase to finish the contraction. This is known as wave summation.
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.
Do bones and muscles work together for movement?
Well, yes but bones have no nerve stimulus so respond to muscle movement.
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 happens at the level of the neuron starting with stimulus and ending with a response?
The stimulus is detected by the sensory receptor. The sensory receptor stimulates a sensory neuron. The sensory neuron transmits to the interneuron in the spinal cord. The interneuron stimulates a motor neuron. The motor neuron communicates to the muscle. The muscle(effector) then produces the response allowing the body to respond to the stimulus.
Stimulus at which the muscle first contracts perceptibly?
Threshold stimulus
Is Concentric in exercise shortening of muscle or not?
Looking form the out side the two bones to which the Muscle is attached moves closer when the muscle is contracting concentrically while they do not when muscle is contracting eccentrically
