What is the function of the muscle fibers?
muscle fibers contract the muscles when stimulated.
Which kind of muscle fibers contract rapidly?
fast twitch
What is it called when white muscle fibers that contract quickly?
striated
Does glycerinated skeletal muscle fibers need calcium in order to contract?
false
Name four factors that influence contractile force and two that influence velocity and duration of contraction?
The four factors that influence contractile force are the number of muscle fibers stimulated, the relative size of the fibers, the frequency of stimulation and the degree of muscle stretch. Factors that influence the velocity and duration of contraction are the muscle fiber type, load and recruitment.
What usually triggers muscle fibers to contract or relax?
The contraction is triggered by the release of calcium within the muscle which is triggered by an electrical signal from a nerve.
What kind of muscle makes your heart?
You call it as cardiac muscles. The muscle fibers contract rhythmically. The muscle fibers are attached to each other end to end. This facilitates the conduction of the impulse. The muscle fiber can be stimulated to give you contraction of the the same.
What is the function of the muscle fibers?
muscle fibers contract the muscles when stimulated.
What is muscle protein?
it is tiny muscle fibers that contract and expand the muscle
What is muscle tone and what caused it?
Muscle tone is the level of firmness or slight contraction in a resting muscle. Nerve fibers are active while the muscles are contracting as messages are unconsciously being fired to maintain this partially contracted state. Here the few muscle fibers contract at any given time.
What happens when these muscles contract?
When muscles contract, the brain sends signals through the nervous system to the motor neuron that supplies several muscle fibers. There are different versions of contraction, which includes voluntary and involuntary.
What is the maximum rate of contraction in normal cardiac muscle fibers?

What is recruitment anatomy?
Increasing the number of muscle fibers involved in the contraction.
What is recruitment in anatomy?
Increasing the number of muscle fibers involved in the contraction.
What type of contraction in which the muscle fibers do not shorten are called?
If the muscle can not shorten because the muscle is trying to move a load that is greater than the force, then the contraction is isometric.
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.
Explain a muscle spasm in terms of recruitment of muscle fibers?
A muscle spasm is the spontaneous recruitment of muscle fibers. The resulting contraction is usually painful, but it typically resolves very quickly.
